The Cuban Missile Crisis occurred in October 1962 when U.S. reconnaissance flights discovered Soviet nuclear missiles installed in Cuba, just 90 miles from Florida. In response, President John F. Kennedy created a committee called EXCOMM to discuss options. They decided on a naval blockade of Cuba to prevent further Soviet weapons shipments. After several tense days, Soviet leader Khrushchev agreed to remove the missiles in exchange for a promise from the U.S. not to invade Cuba, ending the crisis.
