The Bay of Pigs was an operation that was planned to use Cuban exiles to overthrow Fidel Castro's regime in Cuba. Ultimately it failed, resulting in Castro receiving more aid from the Soviet Union to strengthen his grip on power, and the Kennedy administration was embarrassed politically. The whole idea of Vietnam was to contain the spread of communism. Americans believed that if South Vietnam fell to communism, one nation after the other would also fall, until Australia and New Zealand were in danger( this became known as the domino theory). To secure both domestic and national security, America intervened for itself and its allies.
