The history of U.S.-Iran relations has been marked by covert actions, shifting alliances, and decades of tension dating back to the mid-20th century. In 1953, U.S. and British intelligence agencies orchestrated a coup that overthrew Iran’s democratically elected Prime Minister Mohammad Mossadegh. This operation reinstated the Shah, Mohammad Reza Pahlavi, consolidating a pro-Western regime in Iran.
During the reign of the Shah, the United States provided substantial financial and technical assistance. In 1957, the U.S. supported the creation of SAVAK, the Iranian National Security and Intelligence Organization, which played a key role in internal security and suppression of political opposition.
Throughout the 1960s and 1970s, the United States and Iran maintained formal diplomatic relations. One notable agreement occurred during President Dwight D. Eisenhower’s administration under the “Atoms for Peace” program, facilitating cooperation on the civil uses of nuclear energy.
Relations changed dramatically after the 1979 Iranian Revolution, which resulted in the establishment of the Islamic Republic under Ayatollah Khomeini and the subsequent severing of diplomatic ties. Since then, the United States and Iran have experienced largely antagonistic interactions. There were multiple attempts by successive U.S. presidents to engage with Iran diplomatically, but these efforts remained limited and intermittent.
During the 1980s, the Reagan administration, particularly through the Central Intelligence Agency, covertly provided classified intelligence to Iraq during the Iran-Iraq War. This included permitting certain support actions while officially maintaining a stance of neutrality.
Over the years, diplomatic efforts between the two countries have faced numerous challenges, reflecting deep-seated mistrust. Despite the lack of formal diplomatic relations, sporadic negotiations and indirect interactions have occurred at different times.
Today, the history of U.S.-Iran relations remains a backdrop to ongoing geopolitical dynamics in the Middle East. The complex legacy of covert operations, intelligence sharing, and diplomatic ruptures continues to influence the policies and actions of both nations.
