During the 1970s and the Cold War a détente came into place. "A détente is defined as a relaxation in international affairs. Jimmy Carter served as the 39th President of the United States from 1977 to 1981, while Leonid Brezhnev was General Secretary of the Communist Party of the Soviet Union (and thus political leader of the USSR) from 1964 to 1982, serving in that position longer than anyone other than Joseph Stalin."
