The correct answer is D.) ended when the Soviets agreed to remove missiles from Cuba after an American blockade.
Explanation:
This is because after the Cuban missile crisis, the USA engaged in the Cold War. This led to both sides creating nuclear weapons of mass destruction. The US aimed their missiles at the USSR. When it seemed like all was lost, the US decided to withhold their resources from the Soviet Union because the Soviets traded with Cuba regularly. The Soviet leader dismantled all Russian missiles and the US resumed trade with them. That marked the end of the Cold War.
