The Cuban Missile Crisis brought the world's superpowers, the United States and Soviet Union, to the brink of nuclear war as the Soviet Union placed nuclear missiles in Cuba, posing a threat to the US. President Kennedy demanded the missiles' removal to protect American security. After tense negotiations, Soviet leader Khrushchev removed the missiles in Cuba, allowing the US to claim victory through diplomacy rather than war. The crisis demonstrated the importance of peaceful resolution to conflicts between superpowers.
