Operation Mongoose was a covert program initiated by the United States in 1961 aimed at overthrowing Fidel Castro's government in Cuba. This operation emerged from the context of rising tensions during the Cold War, particularly following the failed Bay of Pigs invasion, as the U.S. sought to eliminate the perceived threat of communism so close to its shores. It involved various tactics, including sabotage, psychological warfare, and support for anti-Castro insurgents, reflecting the U.S. government's commitment to countering communist influence in Latin America.
