Stalin didn’t give a damn about communism. Some considered him a double-agent for the Czar. He kept silent about his true allegiance and controlled the communist party as a grand infiltrator. He was alarmed when party hardliners began to complain about his wavering dedication to communist principles. Stalin killed the party leadership during his purge of 1938. When Senator Joseph McCarthy began harassing communists in the U.S. in the early nineteen fifties, Stalin’s communists had been dead for fifteen years.
