Russia has officially withdrawn from a landmark nuclear deal with the United States that required both nations to dispose of 34 tons of weapons-grade plutonium — enough for thousands of warheads.

The Plutonium Management and Disposition Agreement, signed in 2000 and ratified by Moscow in 2011, aimed to convert excess plutonium into civilian nuclear fuel. Russia suspended its participation in 2016, accusing Washington of breaching its obligations.
President Vladimir Putin’s formal withdrawal, signed into law on Oct. 27, follows Russia’s successful test of the Burevestnik nuclear-powered cruise missile. The move drew criticism from U.S. President Donald Trump, who urged Moscow to “focus on ending the war in Ukraine.”
The decision effectively ends one of the last Cold War–era arms control pacts, further eroding the global nuclear security framework.
While Putin has proposed maintaining limits under the New START Treaty, its future remains uncertain ahead of its 2026 expiry.
