The United States blockaded Cuba because the Soviets put missiles on the island. This situation led to a diplomatic crisis, known as the "Cuban Missile Crisis". It was the state of an imminent atomic war between the United States and the Soviet Union in October 1962, as a result of their conflict over Cuba getting out of hand. After a seven-year guerrilla fight in 1959, the island had become communist under Fidel Castro, and had turned to the Soviet Union for military assistance following the failed invasion of Bay of Pigs.

On October 22, 1962, the crisis came out in full publicity when President John F. Kennedy of the United States delivered a fierce speech in which he demanded the dismantling of all Soviet rocket bases in Cuba and announced a blockade on all military goods to the island; the American blockade covered an area of approximately 80 kilometers on international waters, forming an arc around Cuba. The state of readiness of the American army was raised to level DEFCON-2, allowing immediate military intervention against Cuba.
