Cuba is a large island in the Caribbean. In 1959 a revolution took place in Cuba and Fidel Castro came to power. He introduced a Soviet-style government on the island and he looked to the Soviet Union for support. The revolution in Cuba was a great blow to America. A communist state had been set up only 90 miles from the USA. In early 1962 the Americans placed a number of nuclear missles in Turkey, within easy range of many cities of the USSR. Shortly afterwards Khrushchev decided to place missiles on Cuba. In late September 1962, U.S. spy planes flying over Cuba discovered the presence of Soviet-made medium-range nuclear missiles on the island.
