The Cuban Missile Crisis happened because of the placement of Soviet missiles in Cuba, which was seen by the United States as a direct threat to their national security. Tensions between the US and the Soviet Union had been escalating for years, and the decision to place missiles in Cuba was a response to the US placing missiles in Turkey and Italy. This confrontation brought the two superpowers to the brink of nuclear war.
