CIA Overthrow of Arbenz in Guatemala (Operation PBSUCCESS)
In June 1954, the CIA executed Operation PBSUCCESS — a covert programme to overthrow Jacobo Arbenz Guzmán, the democratically elected president of Guatemala. Arbenz had implemented a land reform that expropriated uncultivated land from the United Fruit Company, a powerful American corporation with close ties to the Eisenhower administration. The CIA characterised the reform as evidence of communist influence and organised a small exile army under Colonel Castillo Armas, backed by psychological warfare, radio disinformation, and CIA-piloted aircraft that bombed Guatemala City. Faced with military defections engineered by the CIA, Arbenz resigned on June 27, 1954, and fled into exile. Operation PBSUCCESS was a template that the CIA would apply repeatedly throughout the Cold War. Its apparent success — a cheap, deniable way to remove a problematic government — encouraged the agency to believe covert action could substitute for military force. The agency used the same playbook in Cuba in 1961, with far less success. In Guatemala itself, the coup ended a decade of democratic reform and inaugurated decades of military dictatorship, civil war, and mass atrocity. A CIA-backed counterinsurgency in the 1960s-1980s resulted in the killing of some 200,000 Guatemalans, mostly indigenous Maya, in what a UN-sponsored truth commission later characterised as genocide.
