The Trump administration said Friday that the U.S. will formally begin the process of withdrawing from the Intermediate-Range Nuclear Forces Treaty, the Cold War-era arms control accord with Russia — a move that prompted Russia to announce its own withdrawal on Saturday.
The declaration by Secretary of State Mike Pompeo had been expected for months. He said the U.S. will suspend its obligations under the 1987 INF treaty as of Saturday and pull out in six months if Russia isn't deemed to be in compliance.
