The Cuban Missile Crisis was a 13-day confrontation from October 16-28, 1962, between the United States and Soviet Union over the deployment of Soviet nuclear missiles in Cuba. It reached a critical point on October 22 when President Kennedy announced a naval blockade of Cuba. The crisis, which brought the world to the brink of nuclear war, ended when Soviet Premier Khrushchev agreed to remove the missiles in exchange for a US pledge not to invade Cuba.
