The Cuban Missile Crisis occurred in Cuba in 1962, intensifying the Arms Race and straining US-USSR relations.
Step-by-step explanation:
The relevant event that happened in Cuba in 1962 was the Cuban Missile Crisis. It occurred when the United States discovered that the Soviet Union had placed nuclear missiles in Cuba, just 100 miles from American soil. This event intensified the Arms Race between the US and the USSR, as it brought the two superpowers to the brink of nuclear war. The crisis was resolved peacefully when both sides agreed to remove their missiles, but it strained US-USSR relations and highlighted the tensions and dangers of the Cold War.
