U.S.-Russia Nuclear Arms Control Tracker

For decades, even during the Cold War, U.S. and Soviet/Russian leaders understood the importance of cooperation on nuclear arms control. From the Limited Test Ban Treaty (1963) to the Intermediate-range Nuclear Forces (INF) Treaty (1987) to the Strategic Arms Reduction Treaty (1991), negotiated agreements limited U.S. and Russian nuclear arsenals and helped prevent the spread of nuclear weapons. That cooperation, which reduced the number of nuclear weapons in the world by 85 percent, has fallen apart as both the U.S. and Russia undergo expensive overhauls of their nuclear arsenals — ushering in a new nuclear arms race. 

In 2010, building on previous agreements, Presidents Obama and Medvedev signed New START, limiting both parties to 1,550 strategically deployed nuclear weapons and 700 deployed launchers. The treaty also established verification mechanisms to ensure both parties are adhering to their commitments under the agreement.

Since then, progress has stalled. Offers from the Obama administration to start negotiations for another round of nuclear reductions were rejected by Moscow. Russia’s annexation of Crimea in 2014 and an increasing frequency and aggressive nature of military incidents between the US/NATO and Russia has heightened tensions between the two largest nuclear-armed powers.

Now, under the influence of National Security Advisor John Bolton, the Trump administration is targeting international arms control agreements, pulling out of the INF Treaty and stalling on extending New START past its February 5, 2021 expiration. Russia has said it is ready to discuss extension, warning serious dialogue is needed first and time is running out, but the US administration seems to be stuck in a review process. Trump has ordered his team to focus instead on negotiating a broader deal to include all Russian nuclear weapons and bring China into the fold.

Restarting and expanding talks with Russia and engaging China are admirable goals. These conversations are needed to further nuclear reductions and address relevant national security concerns such as missile defense and cyberwarfare. But it is highly questionable whether negotiation of a new trilateral, or even bilateral, arms reduction treaty is possible before New START expires on February 5, 2021. The US lacks concrete plans and, for its part, China has already said they will not join nuclear reduction negotiations at this stage.

The best way forward on arms control is for the U.S. and Russia to first extend New START. It will keep US and Russian strategically deployed nuclear arsenals capped at 1,550 while the U.S. and Russia, and possibly even China, work on a follow-on agreement. Without New START both the U.S. and Russia will lose important insight into the other’s nuclear arsenal provided by the agreement’s verification measures.

The clock is running. As Global Zero works with our network of former senior-level military and government officials and national security experts to save the agreement, we’ll also be keeping track of U.S. and Russian arms control efforts, updating this tracker as developments unfold.
