Russian President Vladimir Putin has officially terminated the plutonium disposal agreement with the United States, a pact originally established in 2000 aimed at nuclear disarmament. This decision, following the successful test of the Burevestnik nuclear-powered cruise missile, underscores escalating tensions between Moscow and Washington, particularly in light of the ongoing conflict in Ukraine. The suspension of the agreement, which had already been in effect since 2016 due to perceived US antagonism, raises significant concerns regarding the future of global arms control and strategic stability. This development highlights the continuing deterioration of nuclear cooperation and suggests an intensifying arms race, which could impact global security dynamics.
