The Trump administration rejected a proposal by Russian President Vladimir Putin for a one-year extension of a critical nuclear arms-control treaty.
Putin offered to extend New START without preconditions at a meeting of his security council, but national security adviser Robert C. O’Brien called the proposal a “non-starter.”
“We hope that Russia will reevaluate its position before a costly arms race ensues,” O’Brien said in a statement.
The agreement is set to expire in February 2021. The treaty restricts the numbers of strategic nuclear warheads the pair can deploy as well as the missiles and bombers that carry them.
