Tensions with the United States flared in June 2013, when U.S. National Security Agency (NSA) contractor Edward Snowden sought refuge in Russia after revealing the existence of a number of secret NSA programs. Snowden was allowed to remain in Russia on the condition that, in the words of Putin, he stop “bringing harm to our American partners.” After chemical weapons attacks outside Damascus in August 2013, the U.S. made the case for military intervention in the Syrian Civil War. In an editorial published in The New York Times, Putin urged restraint, and U.S. and Russian officials brokered a deal whereby Syria’s chemical weapons supply would be destroyed.
