United States and Soviet Union agree to establish a nuclear “hot line” | June 20, 1963 | HISTORY

To lessen the threat of an accidental nuclear war, the United States and the Soviet Union agree to establish a “hot line” communication system between the two nations. The agreement was a small step in reducing tensions between the United States and the USSR following the October 1962 Missile Crisis in Cuba, which had brought the two nations to the brink of nuclear war.
