The Bay of Pigs invasion in 1961 marked a significant deterioration in U.S.-Cuba relations. The failed attempt by the U.S.-backed Cuban exiles to overthrow Fidel Castro solidified Castro's power and pushed Cuba closer to the Soviet Union. The invasion exposed U.S. weaknesses and arrogance, leading to heightened tensions and an aggressive Cuban stance against American influence. Consequently, this event not only intensified the Cold War conflict but also led to increased support for Castro domestically, reinforcing anti-American sentiment in Cuba and throughout Latin America. It laid the groundwork for future confrontations, notably the Cuban Missile Crisis in 1962.
