American foreign policies in Third World countries were determined by Cold War doctrine. Explain American foreign policy in the Third World during the Eisenhower administration. Be sure to discuss Iran, Guatemala, and Vietnam.

During the Eisenhower administration, American foreign policy in the Third World was heavily influenced by Cold War doctrine, which aimed to contain the spread of communism. This led to the overthrow of the democratically elected Prime Minister of Iran, Mohammad Mossadegh, in 1953, and the installation of the pro-Western Shah, Mohammad Reza Pahlavi. In Guatemala, the CIA orchestrated a coup in 1954 to overthrow the leftist government of Jacobo Árbenz, who was seen as a communist threat. The administration also supported the French in their efforts to maintain control over Vietnam, which eventually escalated into direct American involvement in the Vietnam War. These actions reflected the Eisenhower administration's commitment to preventing the spread of communism in the Third World, often at the expense of democratic principles and the sovereignty of other nations.
