A deactivated Soviet-era SS-4 medium range nuclear capable ballistic missile is displayed at the La Cabana fortress in Havana in this November 26, 2009 file photo. The 13-day missile crisis began on Oct. 16, 1962, when then-President John F. Kennedy first learned the Soviet Union was installing missiles in Cuba, barely 90 miles (145 km) off the Florida coast. After secret negotiations between Kennedy and Soviet Premier Nikita Khrushchev, the United States agreed not to invade Cuba if the Soviet Union withdrew its missiles from the island.
