U.S. suspends sharing nuke information with Russia

New START, which was reupped at the beginning of the Biden administration, caps the number of deployed nuclear warheads at 1,550 and places other limits on the number of nuclear-capable bombers and launchers.

But after Russia recently declared it would no longer abide by the treaty, and stopped sharing information with the U.S. on its stockpiles, the Biden administration had continued following the pact, until now.

“We have not received any daily notifications from them since that time,” Plumb said.

In Monday’s meeting between diplomats from both countries, “Russia responded that they will not be providing that information,” he continued. “And so as a diplomatic countermeasure, the United States will not be providing that information back.

“We are going to continue to examine what other diplomatic countermeasures are appropriate,” he added, “and what we’re trying to do is balance both responding to Russia’s irresponsible behavior but continuing to demonstrate what we believe [what] a responsible nuclear power’s action should be.”
