The CIA's TPBEDAMN Operation and the 1953 Coup in Iran

This article gives an overview of TPBEDAMN, a large covert operation the U.S. Central Intelligence Agency (CIA) carried out in Iran for several years in the early 1950s. TPBEDAMN was a psychological warfare operation intended to undermine the influence of the Soviet Union and its Iranian ally, the Communist Tudeh Party, through covert propaganda and political action activities. When U.S. officials decided in early 1953 to overthrow Iran's prime minister, Mohammad Mosaddeq, they relied heavily on TPBEDAMN's large network of Iranian agents and subagents to plan and implement a coup d'état. The overview of TPBEDAMN presented here helps to clarify both the nature of the organizational apparatus the CIA used against Mosaddeq and the broader context within which the coup occurred, especially the intense Cold War climate that prevailed and the prevalence of psychological warfare in this era.
