Since securing the extension of the 2010 New Strategic Arms Reduction Treaty (New START) in February, the United States and Russia have both signaled a willingness to hold a dialogue on arms control as part of a broader conversation on strategic stability, though when exactly such discussions may take place remains unclear. “The United States is ready to engage Russia in strategic stability discussions on arms control and emerging security issues,” said U.S. Secretary of State Tony Blinken at the Conference on Disarmament (CD) on Feb. 22.

An exercise of restraint at the International Atomic Energy Agency (IAEA)’s Board of Governors meeting may have preserved the space for diplomatic efforts to save the 2015 nuclear deal with Iran, in part due to efforts by the United States and others to sway Britain, France, and Germany from pursuing a gratuitous resolution censuring Tehran. The resolution risked jeopardizing the IAEA’s access to monitor Iran’s nuclear activities, as well as the already uncertain path toward restoration of the accord.The European members of the deal circulated a draft resolution ahead of the quarterly IAEA…

The Arms Control Association team remains in the thick of the debate over how and why the United States and Iran should return to compliance with the historic 2015 nuclear deal. Since President Trump withdrew from the deal in 2018 and reimposed U.S. sanctions, Iran has retaliated by taking steps to ramp up its nuclear program and, in the process, has exceeded key limits set by the agreement. Both governments say they want to return to compliance, but they have not yet agreed as to how. With each passing day, the window of opportunity to avert a renewed nuclear crisis is narrowing. As I…

With only days remaining until its expiration, the United States and Russia officially sealed an extension of the 2010 New Strategic Arms Reduction Treaty (New START) for an additional five years, keeping in place the treaty’s verifiable limits on the deployed strategic nuclear arsenals of the world’s two largest nuclear powers. The U.S. Department of State and the Russian Foreign Ministry issued separate statements Feb. 3 announcing that the formal exchange of documents on the extension had been completed. Biden administration officials stressed that the extension would buy time and…

The 46th President of the United States, Joe Biden, already faces a daunting array of challenges left behind by his predecessor—including major decisions to reduce the threat of nuclear weapons and proliferation that require prompt action. Biden’s national and foreign policy team, along with the new Congress, have an opportunity and a responsibility to restore U.S. global leadership to reduce the threats posed by the world’s most dangerous weapons.

Fate of New START Hinges on Biden With less than two months remaining until the last agreement limiting the U.S. and Russian strategic nuclear arsenals expires, Russia has reiterated its offer to extend the 2010 New Strategic Arms Reduction Treaty (New START). Though President-elect Joe Biden has said that he will seek to extend the agreement, the incoming administration has yet to decide on the length of an extension to seek. “Russia is in favor of extending this treaty for five years without additional conditions,” said Russian Deputy Foreign Minister Sergey Ryabkov Nov. 30. In his annual…

Upon entering office on January 20, 2021, President-elect Joe Biden will have 16 days before the last remaining treaty limiting US and Russian nuclear arsenals, the 2010 New Strategic Arms Reduction Treaty (New START), expires.

The two countries met these limitations by the implementation deadline in 2018. If the treaty expires on February 5, it will be the first time since 1972 that the United States and Russia would have no negotiated…
