The primary outcome of the Bay of Pigs Invasion in April 1961 was a significant defeat for the United States and a diplomatic embarrassment for the Kennedy administration. Aimed at overthrowing Fidel Castro's communist regime in Cuba, the invasion involved training and supporting a group of Cuban exiles to launch an attack on the island. The operation quickly failed due to lack of adequate air support and popular support among Cubans, leading to the capture of many exiles. The failure solidified Castro's power, pushed Cuba closer to the Soviet Union, and demonstrated the risks of U.S. interventionist policy during the Cold War.
