There have been many claims of repeated U.S. Central Intelligence Agency (CIA) intervention in the internal affairs of the Islamic Republic[1] of Iran (Persia), from the 1953 Mosaddeq coup to present. The CIA collaborated with the last Shah, Mohammad Reza Pahlavi, to overthrow Prime Minister Mohammed Mossadeq and install General Fazlollah Zahedi. Later, the 1979 hostage crisis at the American embassy in Tehran, lasting 444 days until January 21, 1981, stemmed from past CIA affairs in Iran, and involvement and collaboration between the two countries requires further analysis to understand the 1979 hostage crisis.
