The United States has joined Russia in extending the last remaining nuclear-arms treaty between the two countries. The announcement by Secretary of State Antony Blinken comes two days before the pact limiting strategic nuclear weapons was due to expire. President Donald Trump had pulled out of two other nuclear arms treaties with Russia, as part of a general withdrawal from international agreements. The Biden administration’s move extends the New START treaty for five years. Blinken says the U.S. will use that time to try for more limits with both Russia and China on the world’s nuclear arsenals.
