U.S.-Saudi Nuclear Cooperation Policy Still Far from Adequate (UPDATED)

UPDATE, Sept. 19 : A day after we published this post, Bloomberg revealed that Energy Secretary Rick Perry's letter to the Saudi's also stated that "The terms of the 123 Agreement [with Saudi Arabia] must also contain a commitment by the kingdom to forgo any enrichment and reprocessing for the term of the agreement." This is good news and the right policy, as we describe below. Such a commitment should have a long-term duration, be legally-binding, and apply to both U.S.-origin and non-U.S. origin fuel. Over the past two years, the Trump administration and Saudi Arabia have been engaged in...

New U.S. Intermediate-Range Missiles Aren’t Needed for Precision Strike in Europe

With the Aug. 2 withdrawal of the United States from the 1987 Intermediate-Range Nuclear Forces (INF) Treaty, which ended the deployment of intermediate-range missiles by NATO and the former Soviet Union in Europe, plans to develop a new generation of treaty-noncompliant missiles have led to fears that they will return to the continent. Defense Secretary Mark Esper referred that same day to the need for “proactive measures” to develop new intermediate-range capabilities in the European theater. The Department of Defense requested nearly $100 million in fiscal year 2020 to develop three new...

China’s Stance on Nuclear Arms Control and New START

The 2010 New Strategic Arms Reduction Treaty (New START) between the United States and Russia is set to expire in February 2021. Although the two nations could extend the treaty by up to five years (and there is bipartisan congressional support for such a step), the future of New START remains uncertain, in part because the Trump administration wants to include China in any future arms control deal. Integrating China further into international nuclear arms control efforts is a worthy goal, but extending New START should not hinge on China’s participation. Given China’s relatively minimalist...

NATO Secretary-General Stoltenberg's INF Response Is Inadequate

Russian pursuit of the 9M729 intermediate-range missile, which is banned under the 1987 Intermediate-Range Nuclear Forces (INF) Treaty, is unacceptable and merits a strong response. But NATO Secretary-General Stoltenberg’s formula, as expressed in a new op-ed published in the German-language Frankfurter Allgemeine , is inadequate. In his July 14 essay, the Secretary-General embraces the Trump administration’s decision to terminate the treaty August 2 without a realistic plan to help resolve the long-running compliance dispute. This move, combined with the possibility of new U.S. ground-...

The Impact: Iran Breaches Nuclear Deal

This blog post originally appeared on the U.S. Institute of Peace's " The Iran Primer ," July 8, 2019. Since July 1, Iran has engaged in two breaches of the 2015 nuclear deal. On July 1, it increased its stockpile of low-enriched uranium above the 300-kilogram limit. On July 8, it increased enrichment from the limit of 3.67 percent to 4.5 percent. Iran had previously complied with the agreement, even after President Trump abandoned it in May 2018. What do Iran’s decisions mean for the future of the JCPOA (Joint Comprehensive Plan of Action) ? Iran’s decision to breach the 300-kilogram limit...

U.S. Questions Russian CTBT Compliance

A top U.S. intelligence official publicly accused Russia in May of not complying with the 1996 Comprehensive Test Ban Treaty (CTBT), raising concerns that the Trump administration may be considering withdrawing from another multilateral arms control agreement. The allegation is a significant shift from recent U.S. government and intelligence community assessments. “Russia probably is not adhering to its nuclear testing moratorium in a manner consistent with the ‘zero-yield’ standard” outlined in the CTBT, said Lt. Gen. Robert Ashley, the director of the Defense Intelligence Agency (DIA), in...

Passion and Diversity at the 2019 CTBTO Science and Technology Conference

The conference brought together over one thousand participants, representing the most diverse regions of the world, and gathered their ideas and perspectives at the conference grounds. The first conference day highlighted several pertinent topics, such as: youth as the advocates of progress towards CTBT ratification, gender equality in the science and technology field, and the role of expert communities in arms control...

Despite Threat to Breach Limits, Iran Remains Below the Nuclear Deal’s Caps

The International Atomic Energy Agency’s (IAEA) most recent report on Iran’s implementation of the 2015 multilateral nuclear deal indicates that Tehran continues to adhere to the accord’s limits—a positive development after President Hassan Rouhani announced that Iran would reduce compliance with the agreement. Specifically, the Supreme National Security Council stated May 8 that Iran would no longer be bound by the stockpile limits on heavy water and low-enriched uranium (LEU) put in place by the nuclear deal, known as the Joint Comprehensive Plan of Action (JCPOA) . According to the May 31...

U.S.-Russian Nuclear Arms Control Watch, May 2019

U.S.-Russian Arms Control Talks to Begin Amid Uncertainty Following a May 14 meeting in Sochi, Russia with Russian President Vladimir Putin and Foreign Minister Sergey Lavrov, Secretary of State Mike Pompeo told reporters that the two countries “agreed that … we will gather together teams that will begin to work not only on [the 2010 New Strategic Arms Reduction Treaty] New START and its potential extension but on a broader range of arms control issues that each of our two nations have.” But it remains unclear when such talks will begin, who will lead the U.S. negotiating team, what the Trump...

Reporting on the 2019 NPT PrepCom

NPT Looks Ahead to 2020 Review Conference Without Consensus Recommendations May 10, 2019 NPT states-parties failed to adopt a common set of recommendations for the 2020 Review Conference on the final day of the two week-long 2019 PrepCom on Friday, May 10. Nevertheless, most states expressed optimism in concluding statements about prospects for next year’s review conference and underlined the importance of action in the intervening 12 months on key NPT-related commitments. The recommendations drafted by the chair, Syed Hussin of Malaysia, failed to garner consensus especially after a round of...
