The document summarizes the key events of the Cuban Missile Crisis in 1962. It describes how the Soviet Union placed nuclear weapons in Cuba, which led to a major confrontation between the US and USSR as they brought the world close to nuclear war. Through secret negotiations and naval blockades, the crisis was eventually resolved when the Soviets agreed to remove the missiles from Cuba in exchange for the US removing missiles from Turkey and Italy. The crisis highlighted the dangers of the Cold War and motivated both sides to establish communication links to prevent future crises from escalating.
