Biden proposing 5-year extension of nuke treaty

Pact expiring on Feb. 5 is last remaining agreement constraining U.S. and Russian nuclear weapons

WASHINGTON — The Biden administration is proposing to Russia a five-year extension of the New START treaty limiting the number of U.S. and Russian strategic nuclear weapons, U.S. officials said Thursday.

Biden’s national security adviser Jake Sullivan planned to convey the extension proposal to Russia’s ambassador to the U.S., Anatoly Antonov, on Thursday afternoon, said one official, who spoke on condition of anonymity to discuss a matter not yet publicly announced by the administration. A second U.S. official, also speaking on condition of anonymity, confirmed the proposal but offered no details.

The move, providing an early signal of Biden’s intent to pursue arms control, is almost certain to be welcomed both by Russia and key American allies. NATO Secretary-General Jens Stoltenberg on Thursday called on the United States and Russia to extend the treaty and to later broaden it.

“We should not end up in a situation with no limitation on nuclear warheads, and New START will expire within days,” Stoltenberg told reporters in Brussels.

Stoltenberg underlined that “an extension of the New START is not the end, it’s the beginning of our efforts to further strengthen arms control.”

The treaty is set to expire Feb. 5 and is the last remaining agreement constraining U.S. and Russian nuclear weapons. Signed in 2010 by former U.S. president Barack Obama and former Russian president Dmitry

Medvedev, it limits each country to no more than 1,550 deployed nuclear warheads.

Obama won Senate ratification of the treaty with a commitment to move ahead with a vast and enormously expensive recapitalization of the U.S. nuclear force. That program, which some Democrats in Congress call excessive, is likely to be further scrutinized by the Biden administration. At a projected cost exceeding $1 trillion (U.S.) over the next several decades, the plan is to replace each of the three “legs” of the U.S. nuclear triad — ballistic missile submarines, nuclear-capable bomber aircraft and land-based nuclear missiles.

Former president Donald Trump had been highly critical of New START, asserting that it put the United States at a disadvantage. His administration waited until last year to engage Russia in substantive talks on the treaty’s future. Trump insisted that China be added to the treaty, but Beijing rejected the idea out of hand.

Trump’s lead negotiator on New START with the Russians, Marshall S. Billingslea, wrote on Twitter on Thursday that Biden would be making a mistake by quickly agreeing to a fiveyear extension.
