Cuban Missile Crisis (WJEC Eduqas GCSE History): Revision Note
Exam code: C100
Summary
The Cuban Missile Crisis was the closest that the world ever came to nuclear war. Its origins lay in the bad relations between Cuba and the United States. This was due to decades of what many Cubans saw as US interference in their country. When a revolution overthrew the Cuban leader whom the US had put in power, America helped Cuban exiles to launch an invasion. The invasion, known as the Bay of Pigs, was a disastrous failure and damaged America’s reputation. It also pushed the new Cuban leader, Fidel Castro, closer to the USSR.
When an American spy plane spotted missile launch sites being constructed in Cuba, it triggered what became known as the Cuban Missile Crisis. US spies discovered that nuclear missiles were at sea on their way to Cuba and, once installed, would mean that all US were in danger of nuclear destruction.
The US President, John F. Kennedy, responded by publicly announcing that the Soviet ships would be stopped from travelling to Cuba. Soviet leader Nikita Khrushchev stated that the ships would not turn back. For several days, it appeared as if a third world war fought with nuclear weapons was very likely. However, Khrushchev agreed to turn the ships around in exchange for America removing its missile bases in Türkiye. Nuclear war had been averted.
Cuba was historically important to the USA both economically and politically. In 1898, the USA helped Cuba gain independence from Spain. Throughout the 20th century, American businesses invested heavily in Cuba’s raw materials, especially sugar. In 1925, Cuba produced five million tons of the world's 25 million tons of sugar. By the 1950s, the USA had a strong economic influence and believed this gave them the right to be involved in Cuban politics.
Geographically, it was important for the USA to maintain a good relationship with Cuba. Cuba is only 90 miles away from the USA. An enemy of the USA could ally with Cuba to use its proximity to attack or invade the USA.
