Both countries met the limits spelled out in the treaty by February 2018 and appear to have remained at or below them since then, according to the State Department. The future of the agreement has appeared in jeopardy at several points since it was signed, however. President Donald Trump’s administration called the treaty “deeply flawed” since it didn’t encompass shorter-range, “tactical” nuclear weapons. Talks to extend the agreement stalled under Trump, and his administration withdrew from a separate agreement with Russia that banned intermediate-range missiles. The Biden administration reached an agreement with Moscow in early 2021 to extend New START until February 2026 “because it was clearly in the security interests of our country and actually in the security interests of Russia,” Secretary of State Antony Blinken told reporters in Greece on Tuesday. But regular inspections mandated by the agreement have not been held for the past three years — initially because of the coronavirus pandemic, and later because relations soured after Russia invaded Ukraine. In November, Russia unilaterally postponed a technical meeting with U.S. officials about the treaty, citing “political reasons.” In a report to Congress last month, the State Department said the United States “cannot certify the Russian Federation to be in compliance” with the treaty since Russia had refused to allow U.S. inspections on Russian territory. The report raised concerns about Russia’s compliance with the warhead limit, which the latest data indicated the country had nearly reached.
