Nuclear Testing

North Korea Urged to Sign CTBT


North Korean leader Kim Jong Un’s statement announcing the closing of the Punggye-ri nuclear test site has led to calls for Pyongyang to sign and ratify the 1996 Comprehensive Test Ban Treaty (CTBT). Federica Mogherini, the EU foreign policy chief, noted in a statement that Kim’s announcement was a positive “long-sought-after” step toward several disarmament commitments and the ratification of the CTBT. Lassina Zerbo, the Comprehensive Test Ban Treaty Organization (CTBTO) executive secretary, called for North Korea to consider signing and ratifying the CTBT, noting that a legally binding treaty is the only way to “solidify the moratorium on nuclear testing.” The CTBTO “stands ready to assist,” he said in an statement April 21, and some experts have proposed having the body engage in confidence-building site visits to Punggye-ri. —SHERVIN TAHERAN

More than two decades after the opening for signature of the Comprehensive Test Ban Treaty (CTBT), the treaty has near universal support and has established a global norm against nuclear test explosions. The nuclear testing taboo impedes the development of new and more advanced nuclear warhead designs, which helps prevent dangerous nuclear competition, and maintain international security.

Although the CTBT has created a norm against testing and a robust technical organization responsible for the operation and maintenance of a highly sensitive global nuclear test monitoring system, the treaty has not entered into force due to the failure of eight key states, including the United States and China, to ratify.

The CTBT is and will continue to be an essential pillar in the global nuclear nonproliferation and disarmament enterprise. Moving closer to the goal of the CTBT’s formal entry into force is the task of every CTBT state party, every nuclear Nonproliferation Treaty (NPT) state-party, every state that supports the new Treaty on the Prohibition of Nuclear Weapons, and any other state that considers itself a “responsible” nuclear actor.

But in order to realize the full potential of the treaty and to close the door on testing, friends of the CTBT will need to rejuvenate and update their efforts to achieve its entry into force and reinforce the taboo against nuclear testing.

For the first five decades of the nuclear age, nuclear weapon test explosions were the most visible symbol of the dangers of nuclear weapons, nuclear arms racing, and the omnipresent danger of nuclear war—or as President John F. Kennedy described it, the nuclear “Sword of Damocles” that hangs over every man, women and child on the planet.

The 1996 Comprehensive Test Ban Treaty has brought the era of frequent nuclear testing to an end and has established a strong norm against any kind of nuclear test explosion. The treaty has near-universal support with 183 signatories, including the five original nuclear testing states.

The Comprehensive Test Ban Treaty Organization (CTBTO), with headquarters in Vienna, is operating on a 24/7 basis to collect and analyze data in real time from a global network of nuclear test monitoring stations. The CTBTO’s International Monitoring System, which is nearly complete and is operating on a 24/7 basis, serves as a strong deterrent against any state that might consider conducting a clandestine nuclear test explosion.

However, the door to nuclear testing remains open as the treaty has not entered into force due to the treaty’s onerous Article XIV provisions, which require that 44 specific states sign and ratify. Currently there are eight “hold out” states—China, the Democratic People’s Republic of Korea (DPRK), Egypt, India, Iran, Israel, Pakistan, and the United States—which have failed to ratify.1

The non-testing norm cannot be taken for granted and, over time, it must be actively renewed and reinforced. In order to realize the full potential of the treaty, to close the door on further nuclear testing, and to reinforce the nonproliferation regime, states must need to rejuvenate their efforts to achieve the entry into force of the CTBT.

Unfortunately, the United States, which was leading proponent for the CTBT during the 1990s is now lagging behind. Without explanation or a high-level review or consultation with allies, the Donald Trump administration announced in February 2018 that it will not seek Senate approval for U.S. ratification of the CTBT.

In response, other hold-out states, particularly China, need to lead the way by signing and/or ratifying the treaty, and all signatory states should reaffirm their support for a permanent, verifiable end to nuclear test explosions by achieving entry into force of the CTBT, including by means of a joint heads of state declaration in the run-up to the 2020 NPT Review Conference.

Supporters of the global norm against nuclear testing and CTBT entry into force should also explore how North Korea’s pledge to close its only known nuclear test site at Punggye-ri beginning April 21 and suspend nuclear testing for the foreseeable future can be solidified into a legally-binding, more verifiable commitment by securing Pyongyang’s signature and ratification of the CTBT through the ongoing diplomatic negotiations with South Korea and the United States on the denuclearization and the establishment of a lasting peace regime on the Korean peninsula.

Regional adherence to the CTBT in the Middle East—and the creation of a regional nuclear weapons test free zone—should also be pursued as a new approach toward building the foundation for a WMD-free zone in the region, which is a long-standing but unfulfilled goal of every state party to the NPT.

The Role of the Comprehensive Test Ban in Nonproliferation and Disarmament

Since 1945, nuclear testing has been used to develop new, more advanced nuclear-warhead designs and to demonstrate nuclear-weapon capabilities. Nuclear testing has propelled the global nuclear-arms competition and undermined global peace and security. In aggregate, at least eight states (United States, Soviet Union, United Kingdom, France, China, India, Pakistan, and North Korea) have conducted more than 2,0562 nuclear test explosions, with U.S. tests accounting for nearly half that total.

For nearly as long, a global, verifiable ban on nuclear test explosions has been a goal for international nuclear risk reduction, nonproliferation, and disarmament. Without the ability to conduct nuclear explosive tests, a country cannot confidently develop more advanced types of nuclear warheads.

A global nuclear test ban was first formally proposed in 1954 by Indian Prime Minister Jawaharlal Nehru as a step toward ending the nuclear arms race and preventing proliferation—and to prevent the significant health and environmental damage produced by atmospheric nuclear-test explosions.

In the negotiations for the 1968 Treaty on the Non-proliferation of Nuclear Weapons (NPT), the CTBT was widely recognized as a critical part of the nuclear-weapon states’ obligation to meet their NPT Article VI commitment to “effective measures relating to cessation of the nuclear arms race at an early date and to nuclear disarmament.”3 The preamble of the NPT specifically cites the goal of “the discontinuance of all test explosions of nuclear weapons for all time and to continue negotiations to this end.”4

Not until the end of the Cold War would the conditions to secure the CTBT finally became more favorable. An important catalyst was the pressure of a popular protest movement in Kazakhstan, which successfully pressed the Soviet government in Moscow to close the Semipalatinsk test site and announce a unilateral nuclear test moratorium in October 1991. Late the following year, the U.S. Congress approved legislation mandating a nine-month U.S. moratorium with conditions on the resumption of nuclear testing. The next year, President Bill Clinton decided to extend the U.S. test moratorium and pursue negotiations on a CTBT at the Conference on Disarmament.

The push for the comprehensive test ban became a key variable in the negotiations between the “nuclear-haves” and the “nuclear-have-not states” at the pivotal 1995 NPT Review and Extension Conference. Support from the NPT’s five recognized nuclear-weapon states for the CTBT gave non-nuclear-weapon states leverage at the NPT conference and contributed to the decision to extend the treaty and adopt a strong “program of action” for disarmament, including the conclusion of CTBT negotiations by the end of 1996.5

Following two years of intense multilateral negotiations, the United Nations General Assembly overcame an attempt by India to block the treaty when it adopted a resolution endorsing the CTBT on September 10, 1996, by a vote of 158-3. Two weeks later, on September 24, the treaty was opened for signature. U.S. president Bill Clinton became the first signatory.

As the Executive Secretary of the Comprehensive Test Ban Treaty Organization, Lassina Zerbo, and Russian Deputy Foreign Minister, Sergei Ryabkov, wrote in an April 2017 essay, Article I of the CTBT prohibits “’any nuclear weapon test explosion or any other nuclear explosion’ anywhere on Earth, whatever the yield.”6 This provision of the treaty is recognized by all of the major negotiating parties to mean that supercritical hydronuclear tests (which produce a self-sustaining fission chain reaction) are banned, but subcritical hydrodynamic experiments (which do not produce a self-sustaining fission chain reaction) are permitted.7

In 1997, the Comprehensive Test Ban Treaty Organization was formally established to work with state parties to build and operate a robust International Monitoring System (IMS) and International Data Center (IDC). Today, the IMS is nearly 90 percent complete, the IDC is fully functional, and the CTBTO is a mature, highly professional, and fully operational organization that is collecting and analyzing information on a continuous round-the-clock basis for the purpose of detecting and deterring clandestine nuclear-test explosions and to provide the technical basis for international responses to noncompliance.

Once the treaty formally enters into force, the verification system will also include the option for short-notice on-site inspections to investigate suspicious events. Information from states’ national intelligence networks, which are more sensitive in some geographic regions, can be taken into account.

In anticipation of the fact that the treaty’s onerous Article XIV entry into force provisions would delay entry into force, Canadian negotiators insisted on a provision in Article XIV that allows for conferences of states-parties to meet every two years to develop strategies and seek ways to accelerate the process toward securing the necessary 44 ratifications. Beginning with the first such conference in 1999, there have been ten such meetings, which have, unfortunately become pro forma affairs that primarily allow states which have signed and/or ratified to reiterate their support, exhort hold-out states to take action, and to develop a modest joint diplomatic outreach plan.

The Nuclear Testing Taboo

Since the CTBT opened for signature it has established a powerful standard of “responsible” behavior. Nations that conduct nuclear tests are outside the international mainstream and will bear the consequences of global isolation. Only one country—North Korea—has conducted nuclear test explosions in this century.

Even India, which strongly opposed the CTBT during and after the conclusion of the negotiations in 1996, has declared a moratorium on nuclear testing following its May 1998 series of nuclear tests.8 Pakistan, which responded with its own nuclear tests weeks later, has also since observed a testing moratorium and declared it would not be the first state in the region to resume nuclear testing.9

International support for the CTBT has been reaffirmed over the years through multiple UN General Assembly resolutions and UN Security Council (UNSC) resolutions. UNSC Resolution 1887 (2009) calls upon all states “to refrain from conducting a nuclear test explosion and to sign and ratify the Comprehensive Nuclear Test-Ban Treaty, thereby bringing the treaty into force at an early date.”10

On the occasion of the twentieth anniversary of the opening for signature of the CTBT in Sept. 2016, the UNSC adopted the first-ever, CTBT-specific resolution (UNSCR 2310), which reaffirms the global norm against nuclear-weapon-test explosions, calls on the eight remaining states that must ratify for entry force to do so, and urges all states to provide their full financial and technical support to the CTBTO. The resolution was formally co-sponsored by forty-two states, including Israel.11

The new UNSC test-ban resolution also formally recognizes the important September 15, 2016, statement12 from the permanent five members of the council expressing the view that any nuclear test explosion would “defeat the object or purpose of the treaty.” The statement gives public expression to the existing legal obligation of all CTBT signatories not to test a nuclear weapon, even before the treaty enters into force.13

The Treaty on the Prohibition of Nuclear Weapons (TPNW) negotiated, which was opened for signature in 2017, further reinforces the CTBT and the non-testing norm. Under the TPNW, states parties may not “test” nuclear weapons or any other nuclear explosive devices.

Nonproliferation and Disarmament Benefits

A global ban on nuclear explosions has been a central element of the nuclear nonproliferation and disarmament enterprise because an effective, comprehensive, verifiable test ban directly constrains the ability of all parties to develop more-advanced nuclear weapons.

As noted in the preamble of the 1996 treaty: “the cessation of all nuclear weapon test explosions and all other nuclear explosions, by constraining the development and qualitative improvement of nuclear weapons and ending the development of advanced new types of nuclear weapons, constitutes an effective measure of nuclear disarmament and non-proliferation in all its aspects.”14

Technically, a state might have some degree of confidence that a simple, relatively cumbersome fission device would work without testing, as the United States did with the Hiroshima bomb in 1945. Today, a country with no or little nuclear-weapons design and nuclear test explosion experience might be able to acquire an ambiguous nuclear deterrent without nuclear-explosive testing, but under the CTBT it could not use a nuclear test to demonstrate that capability, as India did with its first nuclear-test explosion in 1974.

However, the test ban constrains nuclear weapons development by states with little or no nuclear testing experience by blocking the progression from simple fission designs to “boosted” fission designs to two-stage thermonuclear designs with better yield-to-weight ratios.

How far along the developmental ladder a proliferator could go without nuclear explosive testing is not exactly clear, but states intent on acquiring and deploying modern, two-stage thermonuclear weapons compact and light enough to deliver on long-range ballistic missiles would certainly not have confidence in their performance without multiple, multi-kiloton nuclear-test explosions, which would very likely be detected by the CTBTO’s International Monitoring System and national technical means of intelligence.

Despite substantial science and technological advances over the past two decades that can aid in maintaining and extending the service life of existing nuclear warheads, the CTBT also creates a technical barrier for states with a substantial history of nuclear testing who may in the future see new nuclear warhead designs, such as China, France, Russia, the United Kingdom, and the United States.

According to the exhaustive 2012 study by the U.S. National Academy of Sciences on CTBT technical issues, these states “… are unlikely to be able to deploy new types of strategic nuclear weapons that fall outside the design range of their nuclear-explosion test experience without several multi-kiloton tests. Such multi-kiloton tests would likely be detectable (even with evasion measures) by appropriately resourced … national technical means and a completed IMS network.”15

Tailored Strategies to Bring the Eight Hold-Out States Into the Treaty

Movement toward ratification of the CTBT by the remaining hold-out states would strengthen international and regional security, and each of the remaining eight states have good reason to do so. But in order to make progress, advocates of the CTBT in government and in civil society will need to update and tailor their outreach and diplomacy if there is to be a shift in outdated attitudes of the governments of these eight “hard cases.” CTBT states parties will also need to rejuvenate the bi-annual gatherings of foreign ministerial meetings on the CTBT and signatory states at “Article XIV Conferences on Facilitating Entry Into Force” so they are more impactful.

North Korea: The Democratic People’s Republic of Korea (DPRK)’s nuclear program represents the most direct and immediate threat to the global nuclear-test ban enterprise. Pyongyang’s policies with respect to further nuclear testing and the CTBT are inextricably tied to the resolution of long-running security and political disputes with the United States and South Korea, and to resumptions of sustained negotiations on denuclearization and a peace regime on the Korean peninsula.

(Photo: National Nuclear Security Administration)As President Trump and South Korean President Moon Jae-in engage in talks with their DPRK counterpart, it is vital that they seek to solidify Pyongyang’s pledge to halt ballistic missile and nuclear testing and close their nuclear test site, and also to bring an end to further North Korean fissile material production.

For now, North Korea possesses enough plutonium for fewer than a dozen bombs, but if left unchecked, it will amass a larger and more potent arsenal. Additional successful nuclear weapon test explosions will improve confidence in the DPRK’s warhead designs and facilitate the mass production of a compact warhead design that can be delivered on its short- or medium-range ballistic missiles. Further tests long-range ballistic missiles, coupled with additional nuclear testing, would likely expand Pyongyang’s nuclear retaliatory potential.

Although the DPRK’s leaders may no longer be willing to negotiate away their nuclear weapon’s program altogether, the regime in Pyongyang still appears to be willing to freeze and possibly abandon portions of his nuclear program in exchange for improved relations with the United States, a reduction of tension on the Korean peninsula, and the possibility of much-needed foreign economic trade and food and energy aid.

On April 21, the DPRK’s supreme leader Kim Jong-un announced that North Korea had developed smaller and lighter nuclear, high-yield nuclear weapons and their means of deliver and could therefore “… discontinue nuclear test and inter-continental ballistic rocket test-fire from April 21, 2018. The northern nuclear test ground of the DPRK will be dismantled to transparently guarantee the discontinuance of the nuclear test.”

He also said that “…the discontinuance of the nuclear test is an important process for the worldwide disarmament, and the DPRK will join the international desire and efforts for the total halt to the nuclear test.”

Now, as the United States and South Korea and other states in the region pursue diplomacy and pressure to achieve denuclearization, they should seek solidify Kim Jong-un’s no testing pledge by securing North Korean signature and ratification of the CTBT, along with confidence building visits by CTBTO technical teams.

Some have suggested the Punggye-ri test site may not be available for additional nuclear tests because of cavity and tunnel collapses caused by previous nuclear blasts. But, in reality the site could still be used for further tests. Clearly, the DPRK’s pledge to close down its main nuclear weapons test site and join the international effort to halt all nuclear testing is a very significant pledge toward denuclearization that clearly puts the DPRK’s accession to the CTBT within reach.

The DPRK’s April 20 announcement to halt nuclear and ballistic missile tests was welcomed by key leaders, including the European Union’s High Representative Federica Mogherini who, in an April 21 statement, called it a “positive, long sought-after step on the path that has now to lead to the country’s complete, verifiable and irreversible denuclearization, the full respect for its international obligations and all relevant UNSC resolutions, and the ratification of the CTBT.”

In a statement to the 2018 preparatory committee meeting for the 2020 NPT Review Conference, the CTBTO’s Executive Secretary Lassina Zerbo also welcomed the DPRK announcement and added that the “CTBT can provide the security and certainty needed by solidifying the commitment to turn away from nuclear testing.”

Kim Jong-un’s remarks on nuclear testing are consistent with the logic expressed years earlier in a statement about nuclear testing and the CTBT that was delivered by a senior DPRK official at a conference in Moscow in 2012:

“Once the CTBT becomes effective … then there is no doubt that it would make a great contribution to the world peace and stability. [However,] unless the U.S. hostile policy and its nuclear threats are completely withdrawn and a solid and permanent peace regime is in place on the Korean peninsula, the DPRK is left with no other choices but to steadily strengthen its self-defensive nuclear deterrent to the standard it deems necessary.”16

As the United States and the international community explores options to achieve the denuclearization of the Korean peninsula, another option, pending the entry into force of the CTBT, would be for North Korea to begin technical cooperation with the CTBTO so that, in the event there is seismic event in North Korean territory, CTBT teams could use their remote monitoring tools, and potentially on-site confidence building visits, to ensure that Pyongyang continues to respect its nuclear test moratorium commitment.

India and Pakistan: Since their destabilizing tit-for-tat nuclear detonations in 1998, India and Pakistan have stubbornly refused to reconsider the CTBT even though neither country has an interest in or technical justification for renewing nuclear testing.

India and Pakistan could advance the cause of nuclear disarmament and substantially ease regional tensions by converting their unilateral test moratoria into legally binding commitments through the CTBT. Pakistan has said it supports the principles and goals of the CTBT and would welcome a legally binding test ban with India, but leaders in Islamabad have failed to take the first step by signing the CTBT.17

In particular, India’s ongoing campaign for recognition as one of the world’s “responsible nuclear-armed states,” its effort to win support for membership in the Nuclear Suppliers Group (NSG), and obtain a permanent seat on the UN Security Council would get a strong boost if leaders in New Delhi would commit to sign and ratify the CTBT.

The NSG’s 2008 decision to exempt India from the full-scope safeguards standard for civil nuclear trade was taken with the understanding that India would continue to observe a complete nuclear-test moratorium.18 The renewal of nuclear testing by India would re-open that decision and jeopardize its hard-won access to the international civil nuclear technology and uranium market—an “intolerable” price to pay, according to former Indian Foreign Secretary Kanwal Sibal, who noted in 2009: “We will suffer international isolation. It will be a huge setback to our bid for permanent membership of the United Nations Security Council.”19

This makes it all the more logical for New Delhi’s leaders to join the nuclear-test ban mainstream and reinforce global efforts to detect and deter testing by ratifying the CTBT.

For their part, UN member states that are serious about their commitment to the CTBT and nuclear-risk reduction should insist that India and Pakistan sign and ratify the CTBT before they are considered for NSG membership and insist that India should sign and ratify the treaty before its possible permanent membership on the Security Council is considered.

The Middle East: Ratification of the CTBT by Israel, Egypt, Iran—all of which must ratify to trigger CTBT entry into force—and Saudi Arabia would reduce nuclear weapon-related security concerns in the region. It would also help create the conditions necessary to achieve their common, stated goal of a Middle East zone free of nuclear and other weapons of mass destruction.20

“As a stepping-stone towards this long-term objective, a ‘nuclear-test-free zone’ could be created in the Middle East, by way of CTBT ratifications by the remaining states of the region,” High Representative Federica Mogherini suggested in June 2016 at special ministerial meeting in Vienna to mark the twentieth anniversary of the treaty.21

Israel was among the first nations to sign the CTBT in 1996 and has been actively involved in the development of the treaty’s monitoring system and on-site inspection mechanisms. Israel’s Permanent Representative to the International Atomic Energy Agency and CTBTO Merav Zafary-Odiz said in 2016 that: “a regional moratorium [on nuclear testing] could enhance security, and potentially lead to a future ratification of the CTBT. Israel has announced its commitment to a moratorium, it would be useful for others to do the same.”

Unfortunately, Israel has hesitated to take the next steps toward its own ratification of the CTBT—a move that would bring that nation closer to the nuclear nonproliferation mainstream and lend encouragement to other states in the region to follow suit.

Iran has signed the CTBT but has not yet ratified. In September 1999, at the first Conference on Facilitating the Entry-Into-Force of the CTBT, Iranian Foreign Minister Mohammad Javad Zarif, then Iran’s deputy foreign minister, spoke in support of the CTBT and later endorsed a UN conference statement calling for cooperation aimed at bringing the treaty into effect.

Iran is understandably focused on the implementation of the 2015 Joint Comprehensive Plan of Action (JCPOA) and eventual approval of the Additional Protocol to its nuclear safeguards agreement—and the future of the JCPOA itself has been put into doubt as a result of the Donald Trump administration’s critical approach to the agreement.

Regardless of the status of the JCPOA, if over time Iran fails to ratify the CTBT and fully cooperate with the operation of IMS monitoring stations in the years ahead, it will add to concerns about the purpose of its sensitive nuclear-fuel activities.

If the JCPOA survives the Trump era, Iran could help assuage concerns about the purposes of its nuclear program as key JCPOA limits on its uranium enrichment program expire over the course of the next ten-to-fifteen years by making clear its support for and intention to ratify the CTBT in a timely manner.

China’s Potential Leadership Role: China decided two decades ago to join the CTBT regime and become one of the treaty’s early signatories. China’s leaders and officials have consistently expressed their support for the CTBT, but it is clear that China has made a quiet decision to stop short of ratification until the United States completes its ratification process.

To most observers outside of China, there does not appear to be any serious political impediments to Chinese ratification at this time, aside from the inaction of the United States on the CTBT. Beijing’s failure to ratify has likely also given cover for India not to consider ratification more seriously and has undermined the credibility of Beijing’s overtures to Pyongyang to refrain from further nuclear test explosions.

Recently, however, Beijing has been more energetic in its support for the CTBT. With encouragement from CTBTO Executive Secretary Dr. Lassina Zerbo, China has in the past year certified its first five International Monitoring System (IMS) stations, of the twelve it is treaty-bound to certify in order to realize the completion of the global nuclear test detection system.

The first Chinese IMS station, radionuclide station RN21, was certified in December 2016. The most recent four stations include two primary seismic stations, and two other radionuclide stations, all certified between the months of September to December of 2017. These most recent certifications will “fill in an important geographical coverage gap in terms of event detection in the region,” according to a CTBTO press statement.

During a certification ceremony in January 2018 in China, Zerbo commended China for setting a “positive example” for other Member States in regard to its technical engagement, and Vice Director of Equipment Development at the Chinese Department of the Central Military Commission Lt. General Zhang Yulin noted that the certification of the five stations in one year was “of landmark significance.”

In a statement released following a meeting with Zerbo, Chinese Foreign Minister Wang Yi said that the CTBT is “an important pillar of international nuclear disarmament,” and has an “irreplaceable” role. He also noted that China is “willing to deepen” it’s cooperation with the CTBTO and further “promote the construction and certification of follow-up stations,” which will provide further concentrated monitoring of potential nuclear test activity in the region, particularly North Korean activity.22

The United States: The policy of the United States—which has conducted more nuclear weapon test explosions than all other states combined and has the world’s most potent nuclear arsenal—toward the CTBT is perhaps the most important of all the remaining Annex 2 states. Much has changed since the Senate last examined the CTBT in 1999 and rejected the treaty by a 51-48 margin after a brief and highly partisan debate that centered on questions about the then-unproven program to maintain the existing nuclear warheads in the U.S. stockpile without nuclear explosive tests (a.k.a. the Stockpile Stewardship Program) and the then-unfinished global test-ban monitoring system.23

The substantive case for U.S. ratification of the CTBT is stronger than ever. Today, the global monitoring system can detect any militarily significant nuclear test explosion and U.S. stockpile stewardship programs to maintain its nuclear arsenal without nuclear test explosions has proven to be more effective than originally anticipated.24 The United States no longer has a technical or military need for nuclear explosive testing and it is clearly in U.S. national security interests to prevent other states from testing, which would create new nuclear tensions and enable advances in other states’ nuclear weapons arsenals.

Unfortunately, the U.S. Senate is deeply divided and dysfunctional and has not systematically debated the issues related to the CTBT for nearly two decades. Few senators are familiar with the technical issues surrounding the CTBT or its potential benefits.

Worse still, the Trump administration’s 2017 Nuclear Posture Review (NPR) asserts that “the United States does not support the ratification of the CTBT,” even though there is no technical need to resume nuclear testing.25

The review, which generally defines U.S. policy regarding the role of nuclear weapons in security strategy, says “the United States will continue to support the Comprehensive Nuclear Test Ban Treaty Preparatory Committee” and “the related International Monitoring System and the International Data Center.”

The NPR calls upon other states not to conduct nuclear testing and states that “[t]he United States will not resume nuclear explosive testing unless necessary to ensure the safety and effectiveness of the U.S. arsenal ….”26

The Trump administration’s test ban policy implies that it wants to reap the benefits of the CTBT, including obtaining data from the monitoring system, without fulfilling earlier pledges to reconsider ratification of the treaty. Unfortunately, this policy is not likely going to change during the Trump administration and will not change without stronger international pressure from U.S. allies and civil society. With a renewed push for U.S. leadership on CTBT ratification and movement on the treaty by other hold-out states, it is possible that a new administration and a new Senate will take another look at the CTBT, which is clearly in the U.S. and international security interests.

When the United States does eventually ratify the treaty, it can put additional pressure on other holdout states to follow suit. Until then, it is vital that other states continue to reinforce the global taboo against nuclear testing to reduce the risk of renewed nuclear testing and a dangerous cycle of global nuclear-arms competition.

Bottom Line

Moving closer to the goal of the CTBT’s formal entry into force is the task of every NPT state party, every CTBT state-party, every state that supports the new Treaty on the Prohibition of Nuclear Weapons, and any other state that considers itself a “responsible” nuclear actor, because the CTBT is and will continue to be an essential pillar of the global nuclear nonproliferation and disarmament architecture.

Doing so will, however, take political energy, more diplomatic creativity, and a more serious and sustained commitment from national and international leaders in government and in civil society, beginning now.

Vajpayee said that India’s series of five underground tests, conducted on May 11 and 13, 1998, “do not signal a dilution of India’s commitment to the pursuit of global nuclear disarmament. Accordingly, after concluding this limited testing program, India announced a voluntary moratorium on further underground nuclear test explosions.” He went on to say that: “We conveyed our willingness to move towards a de jure formalization of this obligation. In announcing a moratorium, India has already accepted the basic obligation of the CTBT… .

Description: 

More than two decades after the opening for signature of the Comprehensive Test Ban Treaty (CTBT), the treaty has near universal support and has established a global norm against nuclear test explosions. The nuclear testing taboo impedes the development of new and more advanced nuclear warhead designs, which helps prevent dangerous nuclear competition, and maintain international security.

China Adds Monitoring Stations


China has completed certification in the past year of its first five International Monitoring System (IMS) stations of the 12 it is obligated to certify toward the completion of the global nuclear test detection system managed by the Comprehensive Test Ban Treaty Organization (CTBTO). China is among the eight countries, including the United States, that need to ratify the Comprehensive Test Ban Treaty (CTBT) for the 1996 treaty to enter into force. Both countries have signed but not ratified the treaty.

The first Chinese IMS station, radionuclide station RN21, was certified in December 2016. Two primary seismic stations and two additional radionuclide stations were certified during the September-December 2017 period. These stations “fill in an important geographical coverage gap in terms of event detection in the region,” according to a CTBTO press statement. Chinese Foreign Minister Wang Yi said in a statement that the CTBT is “an important pillar of international nuclear disarmament” and that China is “willing to deepen” its cooperation with the CTBTO.

The monitoring system is about 90 percent complete, with more than 290 stations certified. Once complete, the IMS will have 321 monitoring points, consisting of hydroacoustic, infrasound, seismic, and radionuclide stations and 16 laboratories worldwide.—SHERVIN TAHERAN

China Adds Monitoring Stations

North Korea Tests New Long-Range Missile

January/February 2018
By Kelsey Davenport

North Korea tested a new ballistic missile capable of targeting the entire continental United States, a move that considerably extends Pyongyang’s missile flight range.

This December 12, 2017 photo from North Korea's official Korean Central News Agency shows North Korean leader Kim Jong Un in Pyongyang presenting awards to scientists for their successful work on the Hwasong-15 intercontinental-range ballistic missile. (Photo: AFP/Getty Images)The Nov. 29 test took place just before 3 a.m. in North Korea, and the missile flew on a lofted trajectory for 53 minutes before splashing down in the Sea of Japan about 1,000 kilometers from the launch site. The test, which violates UN Security Council resolutions, was firmly condemned by the international community and escalated concerns about a potential pre-emptive or preventative strike by the United States in response to Pyongyang’s nuclear and missile advances.

North Korea’s Korean Central News Agency (KCNA) heralded the test of the intercontinental ballistic missile (ICBM), designated the Hwasong-15, as a success and described the missile as “capable of carrying super-heavy nuclear warhead and attacking the whole mainland of the U.S.”

David Wright, co-director of the Global Security program at the Union of Concerned Scientists, estimated that the missile would have a range of 13,000 kilometers if flown on a standard trajectory, which would put the entire continental United States within its range. U.S. Defense Secretary Jim Mattis confirmed the range capability on Nov. 28 when he told reporters that the missile could hit “everywhere in the world.”

North Korea did test an ICBM, the Hwasong-14, twice in July, but the estimated range of that system is 10,500 kilometers. (See ACT, September 2017.) At that range, Washington, D.C., would likely have been just out of range, and experts assess that the weight of a nuclear warhead would further reduce that missile’s range.

Like the Hwasong-14, the Hwasong-15 is a two-stage, liquid-fueled system. The Hwasong-15, however, has a number of different characteristics, including a pair of rocket engines powering the first stage, unlike the single-engine Hwasong-14.

Michael Elleman, senior fellow at the International Institute for Security Studies, concluded in a Nov. 30 analysis for the website 38 North that the Hwasong-15 could “deliver a moderately-sized nuclear weapon to any city on the U.S. mainland.” Further, the missile is large and powerful enough to carry decoys or countermeasures that would complicate U.S. missile defense efforts, he said.

Elleman also noted improvements on the Hwasong-15 that would give the North Korean weapon additional accuracy. The missile could be fitted with a postboost control system that could be used to adjust the payload’s velocity and positioning, he said.

When asked about the test, U.S. President Donald Trump told reporters on Nov. 28 that the United States “will deal with it.”

The KCNA announcement said that the test accomplished the “historic cause of completing the state nuclear force” and that North Korea had attained its goal of “completing the rocket weaponry system development.”

A South Korean official told Arms Control Today on Dec. 19 not to read too much into the use of the word “complete.” The official said that North Korea is likely directing that comment at a domestic audience because leader Kim Jong Un set the goal of completing the nuclear arsenal in his Jan. 1, 2017, speech. The officials said that “completion” should not be interpreted as an end of tests.

Many experts and officials assess that North Korea will need to conduct additional tests to demonstrate the reliability of the ICBM. There are continuing doubts about whether North Korea has the technology to ensure that a warhead would survive re-entry into the atmosphere.

Mattis told reporters on Dec. 15 that the Hwasong-15 “has not yet shown to be a capable threat against us right now.” Yeo Suk-joo, South Korean deputy minister for defense policy, said on Dec. 1 that North Korea still needs to prove re-entry and warhead activation.

Elleman made a similar point, noting that more testing is necessary to validate the missile’s performance and verify the re-entry system to ensure that the warhead survives re-entry into the atmosphere. If North Korea is willing to accept “low confidence in the missile’s reliability,” Kim Jong Un could declare the Hwasong-15 combat ready after two or three additional tests, he said.

South Korea responded to the missile test by launching its own precision-strike missiles six minutes after the North Korean test. The South Korean response included army, navy, and air force systems, likely demonstrating that the country’s intelligence agencies detected preparations for the test.

South Korean President Moon Jae-in described the North Korean test as a “reckless provocation” and warned that Pyongyang’s actions may drive the United States to consider a pre-emptive strike against North Korea.

Moon’s concerns about a pre-emptive or preventative strike were reinforced by several U.S. policymakers. U.S. Ambassador to the UN Nikki Haley said that the test brought “the world closer to war” and although the United States does not seek a military conflict, “if war does come, it will be because of continued acts of aggression,” such as the ICBM test.

North Korea tested a new ballistic missile capable of targeting the entire continental United States, a move that considerably extends Pyongyang’s missile flight range.

Defense Bill Restricts CTBTO Funding

The most recent annual National Defense Authorization Act, signed into law on Dec. 12, includes language restricting U.S. financial contributions to the Comprehensive Test Ban Treaty Organization (CTBTO), except for funds related to the International Monitoring System, which detects nuclear test explosions. The CTBTO is the international organization that promotes the Comprehensive Test Ban Treaty in advance of its entry into force and builds up its verification regime.

The U.S. defense authorization bill allows for continued contributions to the monitoring system operated by the Comprehensive Test Ban Treaty Organization.  (CTBTO Preparatory Commission photo)The provision was originally inserted into the House version of the bill. Although not included in the Senate bill, the measure was incorporated into the conference bill, which passed the House on Nov. 14 and the Senate two days later.

The bill also includes an assertion that UN Security Council Resolution 2310, passed in September 2016, calling for the treaty’s early entry into force and the continuation of nuclear testing moratoria does not “obligate the United States nor does it impose an obligation” to refrain from actions that would run counter to the treaty. The amendment’s supporters argue that the United States should not be bound by or contribute financially to a treaty the Senate has not ratified. Opponents of the provision contend that it could signal a weakened U.S. commitment to the global moratoria on nuclear testing and undercut support for the treaty.—ALICIA SANDERS-ZAKRE

The North Korean Missile Crisis

The nuclear danger posed by North Korea is not new. But since the arrival of Donald Trump in the White House, a bad situation has become far worse. Now, as Trump readies for a trip to East Asia, the crisis enters a critical phase.

This July 28, 2017 picture released from North Korea's official Korean Central News Agency (KCNA) on July 29, 2017 shows North Korea's intercontinental ballistic missile (ICBM), Hwasong-14 being lauched at an undisclosed place in North Korea. Kim Jong-Un boasted of North Korea's ability to strike any target in the US after a second ICBM test that weapons experts said could even bring New York into range - in a potent challenge to US President Donald Trump. (Photo: STR/AFP/Getty Images)The risk of conflict through miscalculation by either side now may be as severe as during the tense days of October 1962, when the United States and the Soviet Union nearly went to war over the deployment of Soviet missiles in Cuba.

Now, as then, miscalculation could lead to war and escalation to the nuclear level. Millions of lives in South and North Korea and Japan are at risk. Each side must refrain from further threats and taunts and open a direct, private, and high-level diplomatic channel of communication.

Earlier this year, the Trump administration said its North Korea policy would involve “maximum pressure and engagement.” Since then, we have seen pressure, reckless rhetoric, and threats, not engagement.

North Korea responded with accelerated ballistic missile testing, including two intercontinental-range tests. That led China, North Korea’s major trading partner, to announced it was halting imports of coal, iron, and lead from North Korea.

On Sept. 3, North Korea conducted its sixth and largest nuclear test—a thermonuclear blast having a yield of 150 to 250 kilotons. In response, China and Russia voted for new sanctions at the UN Security Council. China’s central bank has also instructed other Chinese banks to stop providing financial services to North Korea.

In his inaugural address to the United Nations on Sept. 19, Trump worsened the situation. “We will have no choice but to totally destroy North Korea” if it threatens U.S. allies in the region, he said. Trump has ordered regular B1-B strategic bomber flights near North Korea, which Pyongyang sees as a prelude to war. He called North Korea’s authoritarian leader, Kim Jong Un, a “rocket man” on “a suicide mission.”

In his clumsy style, Trump appears to be trying to intimidate Kim. But the history of the nuclear age has shown that 
smaller states, even those without nuclear weapons, are not easily intimidated by U.S. nuclear threats. North Korea is 
no exception.

To show Pyongyang’s determination, Foreign Minister Ri Yong Ho warned that North Korea might conduct a hydrogen bomb test explosion over the Pacific. Ri claims that the United States has effectively declared war on his country and therefore North Korea reserves the right to shoot down any U.S. aircraft that fly over or near its territory.

In October 1962, President John F. Kennedy worked very hard to carefully coordinate all U.S. government messages and signals toward Moscow so U.S. intentions were clear. He exchanged direct, private messages with his Soviet counterpart, Nikita Khrushchev, to seek a way out of the crisis. Kennedy was careful not to rule out certain compromises that would later prove to be essential to resolving the crisis.

But Trump is no Kennedy. The lack of discipline and coordination shown by the Trump administration greatly increases the risk factor. “I think there’s a 10 percent chance the wheels really come off, and we have a full-on war on the Korean peninsula, which would include nuclear use,” warned former NATO Supreme Allied Commander James Stavridis on Sept. 28.

Nikki Haley, U.S. ambassador to the UN, and other U.S. officials have unwisely knocked down Chinese proposals to de-escalate tensions that would involve North Korea halting further nuclear and missile tests in exchange for the United States pausing certain military exercises that North Korea sees as particularly threatening.

If each side can refrain from further threats, it may still be possible for a direct U.S.-North Korean dialogue, without preconditions, that sets a new course toward a negotiated or brokered agreement that addresses the concerns of the international community and the security concerns of North Korea.

A commonsense first step would be an immediate halt to further North Korean nuclear and intermediate- or long-range ballistic missile tests and U.S. military exercises and maneuvers that could be interpreted to be practice runs for an attack.

Given that neither Kim nor Trump has ever been known to publicly back down, however, an outside diplomatic intervention may be in order. The UN secretary-general could convene an emergency, closed-door meeting with senior leaders from the members of the past six-party talks (China, Japan, North Korea, Russia, South Korea, and the United States) and initiate a serious dialogue designed to lower tensions and address issues of mutual concern. A trusted emissary from a third party, such as the Vatican, could pursue shuttle diplomacy. Alternatively, Trump could authorize a personal representative to meet with a senior representative of Kim to work out a plan to reduce tensions.

As Kennedy said 55 years ago following the Cuban missile crisis, “Above all, while defending our own vital interests, nuclear powers must avert those confrontations which bring an adversary to the choice of either a humiliating defeat or a nuclear war.”

Trump Administration Silent on CTBT


October 2017
By Shervin Taheran

At the UN Conference on Facilitating the Entry Into Force of the Comprehensive Test Ban Treaty (CTBT) held Sept. 20, the sole U.S. representative sat silently as senior officials from other nations expressed support for the landmark 1996 accord.

The Trump administration, working without an undersecretary of state for arms control and international security, did not match the high level of representation exhibited by other governments and international organizations. Speakers included foreign ministers and other senior officials, such as EU foreign policy chief Federica Mogherini, UN Secretary-General António Guterres, and Lassina Zerbo, executive secretary of the Comprehensive Test Ban Treaty Organization (CTBTO).

The U.S. silence is particularly notable because the Trump administration is conducting a Nuclear Posture Review, which may include the question of whether the country can adequately maintain its nuclear arsenal without test explosions. The last U.S. nuclear explosive test was Sept. 23, 1992, and many experts have concluded that testing is not necessary to maintain a reliable nuclear stockpile.

The Trump administration has yet to comment publicly about the CTBT, which the United States signed in 1996 but has not ratified. It has commended the CTBTO International Monitoring System and capabilities for detecting nuclear test explosions, notably in the April 7 joint communiqué on nonproliferation and disarmament by Secretary of State Rex Tillerson and other foreign ministers of the Group of Seven.

Although the Trump administration has requested full funding for the CTBTO, in line with previous years, some Republicans in Congress are aiming to “restrict” that funding. (See ACT, March 2017.)

The United States is one of eight countries, known as the “hold-out states,” that must ratify the treaty
before it can enter into force. The others are China, Egypt, India, Iran, Israel, North Korea, and Pakistan. Of the eight, India, North Korea, and Pakistan have not taken the first step of signing the treaty.

Many nations at the session, informally known as the Article XIV conference, after the article in the treaty that advocates its convening, commended last year’s first UN Security Council resolution to specifically support the CTBT. A total of 42 countries, including Israel, co-sponsored Resolution 2310, which came 20 years after the treaty was opened for signature. (See ACT, October 2016.)

Yet, a reference to the resolution was absent in the final declaration of the conference, causing Mogherini to note, “We welcome the positive developments since the 2015 Article XIV conference . . . the adoption of UN Security Council Resolution 2310, which reaffirms the vital importance and urgency of achieving prompt entry into force of the treaty and its universalization. The European Union would have preferred to see a direct reference to this resolution in the final declaration.”

The Treaty on the Prohibition of Nuclear Weapons opened for signature the same morning as the Article XIV conference (See "Fifty States Sign Nuclear Weapons Ban," this issue), where the new accord was frequently mentioned in remarks by officials from countries supporting the new treaty.

Noting concerns among some of the member-states and signatories that the prohibition treaty is in conflict with the CTBT, Alexander Marschik, political director of the Austrian Foreign Ministry, said that the prohibition treaty text “recognizes the vital importance of the CTBT and its verification regime as a core element of the nuclear disarmament and nonproliferation architecture.”

“Its formulations regarding testing were very carefully drafted to ensure they are fully compatible with the CTBT,” he added. “Moreover, there is reason for hope that the success of the new prohibition treaty negotiations will create a positive impulse for our common objective here: the entry into force of the CTBT and the cessation of nuclear testing.”

China and Egypt were the only two “hold-out” states to speak at the conference, and neither offered a clear path on if or when they would ratify the CTBT. China’s statement only alluded to, but did not name, North Korea, the only country now conducting nuclear explosive testing.

Russia also took the opportunity to call out only the United States among the eight “hold-out” states, saying the “U.S. position,” as well as the doubtful effectiveness of the Article XIV process, could “undermine the hope” that the CTBT would eventually enter into force. “We have the impression that some states are satisfied with the current circumstances.”

The Article XIV conference was led by newly elected co-presidents Belgium and Iraq, which took over from Kazakhstan and Japan. Belgium and Iraq will continue in that role for two years until the next Article XIV conference, unless the treaty comes into force thereby eliminating the need for the conference.—SHERVIN TAHERAN

The United States withholds comment while the new administration reviews nuclear weapons policies.

Listen to our European Partners: Sustain the Nuclear Deal with Iran

Before taking action to undermine or violate the nuclear deal with Iran, President Donald Trump and the U.S. Congress would be wise to heed the words of Washington’s European partners in the deal, namely that the agreement is working and renegotiation is futile. Ambassador David O’Sullivan of the European Union, Ambassador Peter Wittig of Germany, Ambassador Gerard Araud of France, and Ambassador Kim Darroch of the United Kingdom, joined forces to deliver these messages at the Atlantic Council Sept. 25 , just three weeks ahead of the Oct. 15 deadline for Trump to issue or withhold a...

Civil Society Leaders Call for Renewed Action to
Bring Nuclear Test Ban Treaty Into Force at UN Conference
 

Note Absence of U.S. Voice on Test Ban in Wake of North Korean Nuclear Test

For Immediate Release: Sept. 20, 2017

Media Contacts: Daryl G. Kimball, Executive Director, Arms Control Association (202-277-3478, [email protected]) and Kathy Crandall Robinson, Interim Director, Women’s Action for New Directions, 202-577-9875 ([email protected])

(New York)—At the tenth Conference on Facilitating Entry into Force of the Comprehensive Test Ban Treaty (CTBT)—also known informally as the Article XIV conference—held at the United Nations in New York, a diverse group of nongovernmental nuclear nonproliferation and disarmament leaders, as well as former government officials and diplomats are calling for renewed action to finally bring the 1996 CTBT into force.

The statement from more than 40 civil society leaders, delivered by Kathy Crandall Robinson from Women’s Action for New Directions, notes that “[i]nternational support for the CTBT has been reaffirmed over the years through multiple UN General Assembly resolutions and UN Security Council resolutions, including 2016’s Resolution 2310 and the new Treaty on the Prohibition of Nuclear Weapons, but our work is not yet done.” 

“In order to realize the full potential of the CTBT and to close the door on further nuclear testing, we need to secure the entry into force of the treaty,” the civil society statement urges, "[s]upporters of the CTBT need to undertake new and sustained diplomatic and outreach efforts to help underscore the political and security value of the treaty for each of the eight remaining CTBT 'hold-out' states and the international community." 

The full text of the statement is below or click here for the PDF.

Unfortunately, the United States, one of the key states that must ratify before it can enter into force, attended but failed to speak at the conference.

“In the wake of North Korea’s sixth and most powerful nuclear test, it is essential that Washington join with its allies and the international community in reiterating the United States’ support for a permanent, verifiable end to all nuclear weapons testing,” said Daryl Kimball, executive director of the Arms Control Association, which organized the civil society statement.

The United States, which was the first country to sign the treaty 21 years ago, is one of the eight “hold-out” states that must still ratify the treaty to trigger its formal entry into force. The other hold-outs include: China, North Korea, Egypt, India, Israel, India, and Pakistan. The CTBT has been signed by 183 states and ratified by 166.

The civil society leaders also called upon the UN General Assembly and UN Security Council members to more fully utilize the CTBTO by calling upon the Executive Secretary to report to these bodies and "supply information or provide other assistance relating to the treaty, including technical reports on the DPRK nuclear tests, the status of global nuclear test monitoring, and activities related to efforts to facilitate entry into force of the CTBT.”

Past Time to Finish What We Started 

Civil Society Statement to the 10th Article XIV Conference on
Facilitating Entry Into Force of the CTBT 

Sept. 20, 2017

A global, verifiable, legally binding comprehensive ban on all types of nuclear test explosions has been a goal for international nuclear-risk reduction, nonproliferation, and disarmament since the beginning of the nuclear age.

The Comprehensive Nuclear-Test-Ban Treaty (CTBT) is the result of years of campaigning by civil society organizations and ordinary people around the globe concerned about the adverse health and environmental effects of nuclear weapons testing and the dangers of the nuclear arms race. The CTBT is the result of the courageous leadership displayed by key political and diplomatic leaders.

Two decades after the opening for signature of the CTBT, the treaty has near universal support and has established a global norm against nuclear test explosions. Nations that conduct nuclear tests are now considered outside the international mainstream and bear the consequences of global isolation. Only one country—North Korea—has conducted nuclear test explosions in this century. 

By prohibiting all nuclear weapon test explosions, the CTBT creates an important barrier against the development of new and more advanced nuclear warhead designs, which, in turn, helps prevent dangerous nuclear competition and advance the twin goals of nonproliferation and disarmament.

The CTBT Organization (CTBTO), established by the international community to provide international oversight for verification of the CTBT, has developed increasingly sophisticated tools and techniques to effectively verify compliance with a “zero-yield” nuclear test ban. 

The CTBTO’s International Monitoring System, which is more than 90% complete and is operating on a continuous 24/7 basis, already serves to detect and deter nuclear test explosions, and provides additional data for other applications. The CTBTO, with technical support and financial contributions of key member states, has also refined the advanced tools and techniques necessary for on-site inspections, which can, once the treaty enters into force, be used to investigate suspect events.[1]

International support for the CTBT has been reaffirmed over the years through multiple UN General Assembly resolutions and UN Security Council (UNSC) resolutions. 

  • UNSC Resolution 2310, adopted in September 2016, reaffirmed the widespread global support for the CTBT, reinforced the norm against testing, expressed strong support for the work of the CTBTO, and recognized that the 183 state signatories of the CTBT are obliged not to take any action contrary to the object and purpose of the treaty, including by conducting nuclear test explosions.
  • The new Treaty on the Prohibition of Nuclear Weapons (TPNW) negotiated earlier this year, though not endorsed by all of the CTBT’s signatories, further reinforces the CTBT and the non-testing norm. Under the TPNW, states-parties may not “test” nuclear weapons or other nuclear explosive devices. 

But our work is not yet done. In order to realize the full potential of the CTBT and to close the door on further nuclear testing, we need to secure the entry into force of the treaty.

Supporters of the CTBT need to undertake new and sustained diplomatic and outreach efforts to help underscore the political and security value of the treaty for each of the eight remaining CTBT “hold-out” states and the international community.

It is essential that the incoming co-chairs of the Article XIV process Belgium and Iraq—in coordination with the previous co-chairs Japan and Kazakhstan, other key CTBT states-parties, and civil society—develop a pragmatic, effective, and dynamic action plan to advance prospects for ratification and entry into force. That plan must also be designed to ensure that the financial and technical support for the CTBTO remains steady and strong so as to maintain the capacity to verify compliance with the treaty pending its entry into force. 

Concrete action on ratification of the CTBT by the remaining hold-out states would strengthen international and regional security, advance the goals and objectives outlined by Article VI of the nuclear Nonproliferation Treaty (NPT), and advance the interests of the eight states listed in Annex 2 that must still ratify to trigger the treaty’s entry into force.

India and Pakistan: Since their destabilizing tit-for-tat nuclear detonations in 1998, India and Pakistan have refused to reconsider the CTBT even though neither country has an interest in, or technical justification for, renewing nuclear testing. India and Pakistan could advance the cause of nuclear disarmament and substantially ease regional tensions by converting their unilateral test moratoria into legally binding commitments through the CTBT. Pakistan has said it supports the principles and goals of the CTBT and would welcome a legally binding test ban with India, but leaders in Islamabad have failed to take the first step by signing the CTBT.

India’s bid for membership in the Nuclear Suppliers Group (NSG) and its effort to win support for a permanent seat on the UN Security Council would get a strong boost if leaders in New Delhi would signal their commitment to sign and ratify the CTBT. Pakistan could make a more convincing case that it is a “responsible” nuclear-armed state if it were to sign and ratify the CTBT. UN member states—particularly those in the Non-Aligned Movement (NAM) and in the NSG—that claim to be serious about their commitment to the CTBT and nuclear nonproliferation should insist that India and Pakistan sign the CTBT before they are considered for NSG membership.

The Middle East: Ratification of the CTBT by Israel, Egypt, and Iran—all of which must ratify to trigger CTBT entry into force—and Saudi Arabia would reduce nuclear weapon-related security concerns in the region. It would also help create the conditions necessary to achieve their common, stated goal of a Middle East zone free of nuclear and other weapons of mass destruction. “As a stepping-stone towards this long-term objective, a ‘nuclear-test-free zone’ could be created in the Middle East, by way of CTBT ratifications by the remaining states of the region,” EU foreign policy High Representative Federica Mogherini suggested in June 2016 at the special ministerial meeting in Vienna to mark the twentieth anniversary of the treaty.

Israel was among the first nations to sign the treaty in 1996 and has been actively involved in the development of the treaty’s monitoring system and on-site inspection mechanisms. In 2016, Israel’s Permanent Representative to the International Atomic Energy Agency and CTBTO Merav Zafary-Odiz said: “a regional moratorium [on nuclear testing] could enhance security, and potentially lead to a future ratification of the CTBT. Israel has announced its commitment to a moratorium, it would be useful for others to do the same.”  Unfortunately, Israel has hesitated to take the next steps toward its own ratification of the CTBT—a move that would bring that nation closer to the nuclear nonproliferation mainstream and lend encouragement to other states in the region to follow suit.

In September 1999, at the first Conference on Facilitating the Entry Into Force of the CTBT, Iranian Foreign Minister Mohammad Javad Zarif, then Iran’s deputy foreign minister, spoke in support of the CTBT and later endorsed a UN conference statement calling for cooperation aimed at bringing the treaty into effect. Iran is understandably focused on the implementation of the 2015 Joint Comprehensive Plan of Action (JCPOA) and eventual approval of the Additional Protocol to its nuclear safeguards agreement. But if Iran fails to ratify the CTBT and fully cooperate with the operation of its IMS monitoring stations in the years ahead, it will add to concerns about its commitment under the JCPOA not to undertake prohibited weaponization-related activities. Iran could help assuage such concerns by making clear its support for, and intention to ratify, the CTBT in a timely manner.

China and the United States: China decided two decades ago to join the CTBT regime and became one of the treaty’s early signatories. China’s leaders and officials have consistently expressed their support for the CTBT, but it is clear that China has made a quiet decision to stop short of ratification until the United States completes its ratification process. To most observers outside of China, there do not appear to be any serious political impediments to Chinese ratification at this time, aside from U.S. non-ratification. Beijing’s failure to ratify has likely given cover for India not to consider ratification more seriously and has undermined the credibility of Beijing’s overtures to Pyongyang to refrain from further nuclear test explosions.

Chinese leadership is important and overdue, but stronger U.S. leadership is also essential. Much has changed since the Senate last examined the CTBT in 1999 and rejected the treaty by a 51-48 vote after a brief and highly partisan debate that centered on questions about the then-unproven stockpile stewardship program and then-unfinished global test-ban monitoring system.

The United States no longer has a technical or military need for a nuclear explosive testing option and it is clearly in U.S. national security interests to prevent other states from testing, which would create new nuclear tensions and enable advances in other states’ nuclear weapons arsenals.

President Trump’s administration has expressed support for the global nuclear test moratorium and the CTBTO’s international monitoring system. At the same time, his administration is being pressured by some in Congress to repudiate the U.S. commitment not to conduct nuclear explosive tests and to develop new types of low-yield nuclear weapons with “tailored” effects that could require nuclear explosive testing to confirm their performance. 

Now is the time for U.S. partners to remind the White House that the pursuit of new types of “more usable” nuclear weapons is destabilizing and that the current global testing taboo cannot be taken for granted. All states at this conference must make it a priority to remind the current U.S. administration, at the highest levels, that Washington has a responsibility and opportunity to reconsider and pursue ratification of the CTBT.

North Korea: The Democratic People’s Republic of Korea (DPRK) is the only nation continuing to flout the global norm against nuclear testing. Their sixth nuclear weapon test was measured by the CTBTO as a magnitude 6.1 seismic event, which means the nuclear bomb produced an explosion in excess of 120 kilotons TNT equivalent, and perhaps much higher. This test, and any future nuclear tests, will undoubtedly help North Korea optimize its nuclear warhead designs for ballistic missile delivery. Although North Korea’s leaders may no longer be willing to negotiate away their nuclear weapons program altogether, they still appear to be willing to halt further nuclear testing in exchange for a reduction of tensions on the Korean peninsula. In a rare statement on the CTBT delivered in Moscow in 2012, a senior DPRK official said: “Once the CTBT becomes effective … then there is no doubt that it would make a great contribution to the world peace and stability. [However,] unless the U.S. hostile policy and its nuclear threats are completely withdrawn and a solid and permanent peace regime is in place on the Korean peninsula, the DPRK is left with no other choices but to steadily strengthen its self-defensive nuclear deterrent to the standard it deems necessary.”[2]

It is in the security interests of Washington, Beijing, and their allies and neighbors in Asia to seek to leverage the international sanctions against Pyongyang and immediately engage in negotiations to halt to further long-range ballistic missile testing and secure a permanent ban on further nuclear testing though its signature and ratification of the CTBT, which are key steps toward the denuclearization of the Korean peninsula.

Moving closer to the goal of the CTBT’s formal entry into force is the task of every CTBT state-party because the CTBT is and will continue to be an essential pillar in the global nuclear nonproliferation and disarmament enterprise. 

Doing so will, however, take political energy, and a more serious and sustained commitment

North Korea’s most recent nuclear test explosion is yet another reminder of why CTBT entry into force and the ongoing work of the Comprehensive Test Ban Treaty Organization is so vital to every state’s security interests: nuclear-armed and non-nuclear-weapon states; supporters as well as skeptics of the TPNW; and states inside and outside the NPT regime.

Finally, the devastating health and environmental effects of decades of nuclear testing around the world, which have adversely affected the lives of millions of people—particularly women and children and those in indigenous and underrepresented societies where a majority of the 2,056 nuclear test explosions have been conducted—serve as one reminder of what is at stake.

Our generation of governmental and nongovernmental leaders has a responsibility to those who have suffered the effects of nuclear testing and to future generations to do our part to finally bring the CTBT into force.
