Why is the Cuban Missile Crisis considered a dangerous moment of the nuclear age?

Correct answer: The USA and Soviet Union came close to nuclear war

The direct answer is A: the USA and the Soviet Union came close to nuclear war. In 1962, the Soviet Union placed nuclear missiles in Cuba, very close to the United States. The USA discovered them and imposed a naval quarantine while demanding their removal. For several days, a military confrontation could have produced nuclear conflict. The crisis ended when the Soviet Union removed the missiles and agreements reduced the immediate danger. Option A is correct because the central danger was possible nuclear war between the two superpowers. Option B is wrong because weapons were not eliminated worldwide. Option C is wrong because NATO was not dissolved; it continued. Option D is wrong because the United Nations had been founded in 1945, not during this crisis. Exam cue: Cuban Missile Crisis equals 1962, superpower confrontation and nuclear danger.
