U.S. Support for the CTBTO Enhances U.S. and Global Security

Volume 9, Issue 2, May 2017

At a time when it is more important than ever to reinforce the global norm against nuclear test explosions and to maintain global capabilities to detect nuclear weapons testing by other countries, the Donald Trump administration is proposing severe budget cutbacks at the State Department, including U.S. contributions to key international organizations.
 
According to the Fiscal Year (FY) 2018 budget outline released by the Trump administration in February, his administration “seeks to reduce or end direct funding for international organizations whose missions do not substantially advance U.S. foreign policy interests, are duplicative, or are not well-managed.” No further detail or explanation was provided.
 
The Trump administration is expected to release its full budget request the week of May 22.
 
These funding cuts could include a reduction in the U.S. contribution for the intergovernmental organization responsible for the global nuclear test monitoring system designed to detect and deter clandestine nuclear explosions, the Comprehensive Test Ban Treaty Organization (CTBTO).
 
Such funding cuts would run counter to the value placed on this contribution by Secretary of State Rex Tillerson, who joined with his G7 foreign ministerial counterparts to extoll the value of the CTBTO in their April 11 joint communique on nonproliferation and disarmament. They said in part:

We believe that all States should maintain all existing voluntary moratoria on nuclear weapon test explosions or any other nuclear explosion, and those States that have not instituted such moratoria should do so.
 
The verification regime being established by the Preparatory Commission for the Comprehensive Nuclear-Test-Ban Treaty Organization, in particular the International Monitoring System and International Data Centre, has proven its effectiveness by providing substantive and reliable data on the nuclear tests conducted by North Korea. We strongly encourage all interested States to complete the IMS as a matter of priority.

The statement also recalls UN Security Council Resolution 2310 (passed September 23, 2016) —which calls on all states to ratify the Comprehensive Test Ban Treaty (CTBT), refrain from nuclear testing, and provide support for the CTBTO. The resolution also notes the contribution of the CTBT to nuclear nonproliferation and disarmament.

Past U.S. Support and Results

This is in line with the United States’ longstanding support for the CTBT, which was formally established in 1997.
 
The CTBTO was established with the support of the United States and the other 182 signatories of the CTBT to build, operate, and maintain a robust IMS and International Data Center to detect and deter nuclear weapon test explosions, which are banned by the treaty.
 
Today the IMS is more than 90% complete and is collecting and analyzing information on a continuous 24/7 basis for the purpose of detecting and deterring clandestine nuclear test explosions and to provide the technical basis for international responses to noncompliance.
 
The CTBTO provides additional nuclear test detection capabilities beyond U.S. national means of intelligence and is a neutral source of information that can mobilize international action against any state that violates the global norm against nuclear testing.
 
The total annual budget of the CTBTO was about  $128 million for 2016. The United States provides 22.47% of the CTBTO’s funding. Over the years, the United States has also made voluntary, in-kind contributions including for the operation and maintenance costs of all IMS facilities in the United States and support to the software development for the International Data Center, which analyzes the global monitoring data for nuclear testing activity. These in-kind contributions are valued at more than $5 million USD in 2015 and $9 million in 2016.
 
Although United States signed the CTBT in 1996 and has not conducted a nuclear test explosion in 25 years, the United States is one of eight remaining states that must ratify the treaty in order to allow for its formal entry into force.

The Illogic of the Treaty’s Critics

Unfortunately, a small but influential group of Republican lawmakers are seeking to cut U.S. funding for the CTBTO and undermine international support for the CTBT and the global nuclear test moratorium.
 
Sen. Tom Cotton (R-Ark.) and Rep. Joe Wilson (R-S.C.) introduced legislation on Feb.7 to “restrict” funding for the Comprehensive Test Ban Treaty Organization (CTBTO).
 
The Cotton and Wilson bill  purports not to restrict U.S. funding specifically for the IMS, but in practice any significant reduction in U.S. technical and financial support for the CTBTO would:

  • adversely impact the organization’s ability to operate and maintain existing nuclear test monitoring stations. This is due to the fact that a wide range of organization’s personnel and assets directly or indirectly support the IMS. This includes staff time and technical support for the International Data Centre in Vienna, which processes information provided by IMS operations; and
  • prompt other states to restrict their funding for the CTBTO or possibly withhold data from CTBTO monitoring stations that are based in their territory, thus undermining the capabilities of the system to detect and deter clandestine nuclear testing.

The bill also seeks to undermine the U.S. obligation—as a signatory to the CTBT—not to conduct nuclear test explosions. It calls on Congress to declare that the September 2016 UN Security Council resolution does not “obligate…nor does it impose an obligation on the United States to refrain from actions that would run counter to the object and purpose” of the CTBT, which President Bill Clinton signed in 1996.
 
Contrary to what the Cotton/Wilson bill implies, Resolution 2310 (which was endorsed by 42 states including Israel) does not impose any new obligations on the United States. Rather, UNSC 2310:

  • encourages states to “provide the support required” to the CTBTO and the IMS, and urges states to refrain from nuclear testing and urges those states that have not ratified to do so; and
  • also takes note of the September 15 joint statement by the five permanent Security Council members that formally “recognized” that a nuclear explosion would “defeat the object and purpose of the CTBT.” 

So long as the United States remains a signatory of the CTBT, it is legally obliged not to take actions that would defeat its object and purpose. In other words, like all other 183 signatories, it shall not conduct a nuclear test explosion.
 
However, if Congress were to adopt the Cotton-Wilson bill asserting that the United States is not required to respect our obligations as a CTBT signatory not to test, it would signal to other states that that the United States is seeking to back out of its commitment to a global and verifiable nuclear test ban and is considering the resumption of nuclear weapons testing.
 
That’s not a smart move. With North Korea threatening to conduct a sixth nuclear test explosion, it is essential that the United States reinforce, not undermine, the global nuclear testing taboo
 
Backing off our historically strong commitment to ending nuclear testing at this time could trigger a dangerous chain reaction by other nuclear-armed states and would run afoul of key U.S. allies who strongly oppose nuclear testing and who support the CTBT. Continuing to fund the U.S. contribution to detect and deter nuclear weapons testing enhances national and international security.
