U.S. Tests Ground-Launched Cruise Missile On Aug. 18, less than two weeks after the official collapse of the 1987 Intermediate-Range Nuclear Forces (INF) Treaty, the United States tested a ground-launched variant of the Tomahawk sea-launched cruise missile that would have been prohibited by the treaty. The test was a clear signal that the United States can and will pursue such systems in the absence of the INF Treaty. In a statement, the Defense Department said the “test missile exited its ground mobile launcher and accurately impacted its target after more than 500 kilometers of flight.…

On Aug. 2, President Trump officially withdrew the United States from the landmark 1987 Intermediate-Range Nuclear Forces (INF) Treaty--which eliminated 2,692 nuclear-armed missiles and helped end the Cold War--without a viable plan B on how to prevent a new intermediate-range missile race in Europe. That same day, the new Secretary of Defense Mark Esper told reporters that he would like to see the deployment of intermediate-range missiles in Asia, ideally as soon as possible. The U.S. is also pressing NATO allies to consider intermediate-range missile deployments in Europe. On Aug. 18,…

During his first two and a half years in office, President Donald Trump and his administration have laid waste to numerous international agreements originally designed to strengthen US security, bolster US alliances, and constrain US adversaries. The toll has been particularly high with respect to deals concerning nuclear arms control and nonproliferation. Over the past 14 months, the administration has withdrawn from the 2015 Iran nuclear deal and abandoned the 1987 Intermediate Range Nuclear Forces (INF) Treaty. Both of these valuable agreements have been discarded without a viable plan to…

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…

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…

U.S. Withdraws from INF Treaty; Missile Tests to Begin This Month On Aug. 2, 2019, the United States formally withdrew from the 1987 Intermediate-Range Nuclear Forces (INF) Treaty, prompting harsh reactions from Russia and China and concerns about the beginning of a new, more dangerous phase of global military competition. This treaty, signed in 1987, led to the elimination of 2,692 U.S. and Soviet Union nuclear and conventional ground-launched ballistic and cruise missiles with ranges between 500 and 5,500 kilometers. The United States accused Russia of violating the treaty by testing,…

Last month, after lengthy deliberations and debate, the House of Representatives voted on its version of the fiscal year 2020 National Defense Authorization Act (NDAA). The bill incorporates a number of provisions, supported by the Arms Control Association, that would place a much-needed check on the Trump administration’s unnecessary, unsustainable, and unsafe nuclear weapons plans. The House version of the defense authorization bill: prohibits the deployment of a new and more usable low-yield warhead for submarine-launched ballistic missiles as proposed in the Trump administration’s…

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-…

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…

With Further Nuclear Moves, Iran Seeks to Leverage Promised Sanctions Relief Iran announced July 8 that it has started enriching uranium at levels in excess of the limit of 3.67 percent uranium-235 set by the 2015 nuclear deal, known as the Joint Comprehensive Plan of Action (JCPOA). The move is the second troubling retaliatory measure in two weeks by Iran to walk back its compliance with the JCPOA. Last week, Iran exceeded the 300-kilogram limit of its stockpile of low enriched uranium set by the JCPOA. Iran’s moves to curtail compliance with the JCPOA have long been expected. Iranian…
