As Americans gave up hope on Mosaddeq, their propaganda and covert action campaign against the Tudeh, called TPBEDAMN, expanded to include him. In 1953, American CIA and British intelligence agents, began plotting to overthrow Mosaddeq in a coup d'état, in large part because of their fear that "rising internal tensions and continued deterioration ... might lead to a breakdown of government authority and open the way for at least a gradual assumption of control by Tudeh," just as a local communist party had led a coup in Czechoslovakia in 1948, replacing a democratic regime and constitution with a pro-Soviet, one-party Communist government.
