Answer:
US leaders believed that Iranian nationalists were too friendly with communists; therefore, the United States helped restore the former ruler’s son to power.
Step-by-step explanation:
The Iranian coup d'etat of 1953 (also known in the CIA archives as Operation Ajax) was an operation planned by the United Kingdom and the United States to overthrow the democratically elected government of Prime Minister Mohammed Mosaddeq and his cabinet. Thanks to the work of Kermit Roosevelt, who worked for the CIA in a covert operation, he bribed various positions of the Iranian administrations, which facilitated the coup. According to the BBC, Great Britain, motivated by the risk of losing his control over the Iranian oil fields, financed bribes granted to army officers, media and others. The project to overthrow the Iranian government received, in communications from the British and US governments, the name of Operation Ajax. The coup d'etat was finally achieved on August 19, 1953. The sha, Mohammad Reza Pahlavi, was implicated in the events, which gave him the dominant position in Iranian politics.
