Obviously, the relationship between world powers and the country of Iran is very complex and spans over many decades. Although there are too many significant events to detail in this timeline, the following are important historical facts which are relevant to the current crisis unfolding in the middle east:
1953 Coup (Operation Ajax): The U.S., through the CIA, and the UK orchestrated a coup to overthrow Iran’s democratically elected Prime Minister, Mohammad Mossadegh, who had nationalized Iran’s oil industry. This operation reinstated the Shah as the dominant power. The Shah’s regime became closely aligned with U.S. interests, receiving significant military and economic support to counter Soviet influence during the Cold War. This created widespread resentment among Iranians, who viewed the Shah as a U.S. puppet.
The 1979 Iranian Revolution
The 1983 bombing of the U.S. Marine Corps barracks in Beirut, Lebanon, was carried out by a suicide bomber driving a truck laden with explosives. The attack on October 23, 1983, killed 241 U.S. military personnel, including 220 Marines, 18 sailors, and 3 soldiers, and wounded over 60 others. A simultaneous attack targeted the French military barracks, killing 58 French paratroopers and 6 civilians.The attack was attributed to the militant group Hezbollah, a Shia Islamist organization backed by Iran. Specifically, the operation was linked to Hezbollah’s precursor, the Islamic Jihad Organization, a shadowy militant cell that emerged during Lebanon’s civil war (1975–1990). • Court Findings: A 2003 U.S. federal court ruling in Peterson v. Islamic Republic of Iran held Iran liable for the attack, citing evidence of IRGC funding, training, and logistical support for Hezbollah. The court noted that the operation required sophisticated planning beyond the capabilities of local militias alone. • Confessions and Claims: While Hezbollah did not officially claim responsibility at the time, key figures like Imad Mughniyeh, a senior Hezbollah military commander, were later implicated. Mughniyeh, killed in 2008, was indicted by the U.S. for his role in this and other attacks.Iran’s Role: Iran provided financial and operational support through the IRGC, which established training camps for Hezbollah in Lebanon’s Bekaa Valley. Declassified U.S. intelligence from the 1980s confirms Iran’s strategic goal was to expel Western forces from Lebanon, viewing them as obstacles to its influence in the region.
