Due to this, the U.S began to worry Iran would ask for help from the Soviet Union in case the situation against the United Kingdom got too serious. Regardless of this, President Truman refused to get involved, as much as the British and the Prime Minister, Winston Churchill, pleaded. .
President Truman refused to overthrow the Prime Minister because he had been elected fairly and democratically, and that the United States should not be against a government that is led by nationalism due to the fact that was the basis that our country was founded on. Therefore, when Dwight Eisenhower became president, the subject matter was much more easier to convince, especially by the Dulles brothers, who proposed the idea that Joseph Stalin could possibly invade Iran. The Eisenhower government saw the Iranian government as too heavily influenced by the Soviets, and acknowledged the spread of communism even more possible in the near future. During this time, communism was the greatest known threat to America, and this definitely helped motivated American participation in this coup. Because of that, the CIA decided to help the MI6 in the act of taking down Mossadegh in what was called Operation TPAJAX. 4.
After Mossadegh was overthrown on August 19th 1953, the Shah was returned to power. Lasting almost 26 years, the Shah was later removed from power by Islamic fundamentalists.5 Due to U.S involvement in aiding the United Kingdom with the coup, later events that took place would result in complications with U.S. foreign policy. The American hostages taken at Teheran, Iran, in November 1979 were in direct correlation with our involvement in the coup. Also, as stated in the Preface, the Iranian woman claims this was the main reason for the hostage situation. Iran thought that the United States was planning yet again another coup to place the Shah back in power in order to access more oil, since this is what occurred in the 1950s.
