Following the Cuban Missile Crisis, the Soviet Union and the United States sign an agreement to establish the so-called "red telephone" link between Washington, D.C., and Moscow.

The Cuban Missile Crisis, also known as the October Crisis in Cuba, or the Caribbean Crisis, was a 13-day confrontation between the governments of the United States and the Soviet Union, when American deployments of nuclear missiles in the United Kingdom, Italy and Turkey were matched by Soviet deployments of nuclear missiles in Cuba. The crisis lasted from 16 to 28 October 1962. The confrontation is widely considered the closest the Cold War came to escalating into full-scale nuclear war.
