The architects of a landmark 1987 treaty aimed at ridding Europe of nuclear missiles are calling on the Trump administration to abandon its plans to leave the INF—or Intermediate-Range Nuclear Forces Treaty.  In a jointly authored op-ed in The Washington Post, former Soviet leader Mikhail Gorbachev and former U.S. Secretary of State George Shultz warn, “Abandoning the INF Treaty would be a step toward a new arms race, undermining strategic stability and increasing the threat of miscalculation or technical failure leading to an immensely destructive war.” The Trump administration has accused Russia of cheating on its commitments to the INF and said this week the U.S. would pull out of the treaty in 60 days unless Russia changes its behavior. Russia, in turn, accused the U.S. of cheating and warned of “retaliation” if the U.S. walks away from the deal.
