Operation Devil was a covert operation conducted by the United States Central Intelligence Agency (CIA) during the Cold War. The objective was to train and equip indigenous guerrilla forces in North Vietnam to fight against the communist government. The operation was authorized by President Dwight D. Eisenhower in 1954 and lasted until 1962. The CIA provided the guerrillas with weapons, training, and financial support, and also conducted psychological warfare operations. The operation was ultimately unsuccessful, as the guerrillas were unable to gain significant traction against the communist government.
