Secretary of State Mike Pompeo gave Russia a 60-day deadline on Dec. 4, to come into compliance with the Intermediate-Range Nuclear Forces (INF) Treaty.
If Russia fails to take action and destroy the SSC-8 missiles and launchers, which the U.S. says are in violation of the landmark 1987 arms pact, Washington will initiate the formal process to withdraw from the treaty, according to Pompeo.
