President Vladimir Putin has declared that Russia will suspend its observation of the New START treaty, marking a significant setback to the last standing arms control agreement aimed at limiting nuclear arsenals between Russia and the United States. This announcement coincides with Russia's ongoing military operations in Ukraine, a conflict that Putin claims is about reclaiming 'historical lands'. He assured the Russian parliament and senior officials that the military campaign in Ukraine would continue steadily and cautiously, implying a long-term strategy despite the international backlash.

In response to this decision, U.S. Secretary of State Antony Blinken expressed deep concern, calling Russia's suspension of the treaty 'deeply unfortunate and irresponsible'. He highlighted that this move not only increases global risk but also dismantles crucial arms control frameworks that have been in place for years. Blinken's comments underscore a broader worry in the international community about the implications of halting necessary dialogue on nuclear arsenals amidst escalating tensions.

The suspension means that Russia will not be the first to resume nuclear testing, a promise Putin made, although he further stated that any testing by the U.S. would prompt a response from Russia. This development raises serious concerns about the stability of global nuclear deterrence and the potential arms race, reflecting a deteriorating relationship between the two nations as diplomatic channels continue to be strained, particularly over the conflict in Ukraine.
