The CIA installing puppets is how we got the Iranian Revolution.
A history of intervention: The 1953 Iran coup
In 1953, when the United States and the United Kingdom orchestrated a coup to remove Iran's democratically elected Prime Minister, Mohammad Mossadegh. Mossadegh had moved to nationalise Iran’s oil industry, challenging the control of Western companies. In response, the CIA and British Secret Intelligence Service launched Operation Ajax, a covert mission to depose him.
The coup succeeded, reinstating Shah Mohammad Reza Pahlavi and ending Iran's brief experiment with democracy. The US and UK regained access to Iranian oil, and the Shah became a close Western ally. However, he ruled autocratically and used a secret police force, SAVAK, to suppress dissent. This period fostered widespread resentment towards the West, especially the United States, for its role in undermining Iranian sovereignty.
By the late 1970s, opposition to the Shah had reached a breaking point. Millions of Iranians, including secular activists and Islamist groups, took to the streets in protest. In 1979, the Shah was overthrown in the Islamic Revolution, which led to the establishment of the Islamic Republic under Ayatollah Ruhollah Khomeini. The revolution marked a dramatic shift in Iran's domestic and foreign policy and solidified anti-American sentiment that had been building since the 1953 coup.
