I believe you would if you looked into the matter even a little bit. The 5 brief paragraphs below explains quite a bit of what I said.

Several paragraphs from Wikipedia.

According to New York Times correspondent Stephen Kinzer, until the outbreak of World War II, the United States had no active policy towards Iran.[8] During the Cold War following World War II, America became deeply involved in Iranian affairs.

From 1952-53, Prime Minister Mohammed Mossadeq who was appointed as Prime Minister by the Shah began a period of rapid power consolidation, centered on Mossadeq’s nationalization of the Anglo-Iranian Oil Company, now British Petroleum. Established by the British in the early 20th century, Anglo-Iranian Oil Company shared profits (85% British-15% Iran), but the company withheld their financial records from the Iranian government. By 1951 Iranian support for nationalization of the AIOC was intense and the Iranian Parliament unanimously agreed to nationalize its holding of, what was at the time, the British Empire’s largest company.

The United States and Britain, through a now-admitted covert operation of the Central Intelligence Agency (CIA) called Operation Ajax, conducted from the US Embassy in Tehran, helped organize a coup to overthrow Moussadeq. The operation failed and the Shah fled to Italy. After organizing protests against Mosaddeq, a second operation was successful and the Shah returned from his brief exile.

During his reign, the Shah received significant American support, frequently making state visits to the White House and earning praise from numerous American Presidents. The Shah's close ties to Washington and his bold agenda of rapidly Westernizing Iran soon began to infuriate certain segments of the Iranian population, especially the hardline Islamic conservatives.

In 2000, U.S. Secretary of State Madeleine Albright apologized for U.S. involvement in the coup[9] and for U.S. support for the brutal dictatorial regime of the Shah, which repressed political dissents.:[10]
