The United States would like Russia to resume its participation in the Strategic Arms Reduction Treaty. The head of the National Nuclear Security Administration at the US Department of Energy said this during a hearing in the US Congress.
On February 21, Russian President Vladimir Putin announced that Moscow was suspending its Participation in the New START Treaty. He noted that a situation in which the US military is at Russian nuclear facilities, while the United States is fomenting a further escalation of the Ukrainian conflict is simply impossible. The US State Department said that Washington considers it "legally incorrect" for Russia to suspend its participation.
