UPDATE: New START nuclear arms treaty expires with Russia and US agreeing to quick talks while Trump administration accuses China of covert nuclear tests and demands Beijing join future pact.
The New START treaty expired Thursday, leaving no caps on U.S. and Russian nuclear arsenals for the first time in more than half a century. The Kremlin said Friday that Russian and U.S. negotiators discussed the issue during talks in Abu Dhabi and agreed on the need to quickly launch new arms control negotiations. The treaty had restricted each side to no more than 1,550 nuclear warheads on no more than 700 deployed missiles and bombers.
Russian President Vladimir Putin had offered to extend the treaty's limits for another year if Washington followed suit, but President Trump rebuffed the proposal. Trump argues he wants China included in any new pact, which Beijing has rejected. Secretary of State Marco Rubio reiterated that 'an arms control arrangement that does not account for China's buildup will undoubtedly leave the United States and our allies less safe.' The U.S. also accused China of conducting covert nuclear explosive tests, allegations Beijing denied.
New START, signed in 2010, was the last remaining agreement in a long series of nuclear arms control pacts between Washington and Moscow dating back to SALT I in 1972. While Putin suspended Russia's participation in 2023 citing NATO's stated goal of defeating Russia in Ukraine, the Kremlin pledged to respect the treaty's weapons caps. The treaty's expiration fuels fears of an unconstrained nuclear arms race between the world's two largest atomic arsenals.
Editor’s rationale — Expiration of New START treaty has major structural implications for U.S.-Russia nuclear relations and global security architecture, affecting multiple nations and strategic posture for years. Strong institutional impact undermined slightly by lack of new binding agreements yet in place. Global scope confirmed by multi-nation involvement (U.S., Russia, China) and U.N. platform statements. Durable relevance given long-term arms control consequences. Information quality mixed: official statements and diplomatic revelations present, but primary news is agreement to negotiate rather than substantive new policy action.
