Context: The Cuban Missile Crisis, also known as the October Crisis (of 1962) (Spanish: Crisis de Octubre) in Cuba, the Caribbean Crisis (Russian: Карибский кризис, tr. Karibsky krizis, IPA: [kɐˈrʲipskʲɪj ˈkrʲizʲɪs]) in Russia, or the Missile Scare, was a 35-day (October 16 – November 20, 1962) confrontation between the United States and the Soviet Union, which escalated into an international crisis when American deployments of missiles in Italy and Turkey were matched by Soviet deployments of similar ballistic missiles in Cuba.

The confrontation is often considered the closest the Cold War came to escalating into a full-scale nuclear war.
