Tensions between the two nations at the close of World Conflict II were the catalyst for the war. As a result, it had a severe impact on the domestic economy and administration, as well as on Americans' personal lives, fostering a society of anticipated uniformity and routine. The United States, the United Kingdom, and the Soviet Union were the key players in this conflict. Kennedy retaliated by erecting a naval blockade around Cuba, which he referred to as a quarantine. The Cold War was named after the fact that neither the Soviet Union nor the United States had declared war on one other. With the fall of the Soviet Union, the cold war came to an end.
