Here's few select examples from the list showing what the Iranian regime done to American citizens:
April 1983: A suicide car bombing
kills 63 people, including 17 Americans, at the U.S. Embassy in Beirut. The Iran-backed terrorist group Islamic Jihad, a precursor and early branch of Hezbollah (not to be confused with Palestinian Islamic Jihad), claims responsibility.
October 1983: Operatives of the Iran-backed Hezbollah drive a truck bomb at a Marine compound in Beirut,
killing 220 U.S. Marines and 21 other service personnel.
March 1984: Terrorists
kidnap CIA station chief William Buckley in Beirut, subsequently torturing and ultimately killing him in 1985. Islamic Jihad claims responsibility.
July 1989: Hezbollah operatives
kill U.S. Marine Corps Col. William Higgins after kidnapping him the previous year while on a United Nations peacekeeping mission in southern Lebanon.
June 1996: A truck carrying 5,000 pounds of explosives
blows up the Khobar Towers, a U.S. Air Force housing complex in the Saudi Arabian town of Khobar. Nineteen Americans die and some 500 people are injured. The Iran-backed Hezbollah Al Hijaz, a terrorist group in Saudi Arabia, is deemed responsible.
August 1998: With the assistance of Hezbollah, al Qaeda suicide bombers almost simultaneously blow up the U.S. Embassies in Kenya and Tanzania,
killing 224 people, including 12 Americans, and wounding thousands.
September 11, 2001: While the
9/11 Commission Report concludes that Iran had no foreknowledge of al Qaeda's attacks on the World Trade Center, the report indicates that Tehran facilitated the travel of some of the terrorists. "In sum," the report notes, "there is strong evidence that Iran facilitated the transit of al Qaeda members into and out of Afghanistan before 9/11, and that some of these were future 9/11 hijackers."
2003-2011: Iranian-backed militias kill at least 603 U.S. troops in Iraq,
according to the Pentagon. Iranian
training and material support for Iraqi militias during the surge greatly increased the difficulty of U.S. forces to combat the insurgency and included some of the deadliest weapons used against American troops, including explosively formed penetrators (EFPs) and improvised explosive devices (IEDs).
January 2007: Twelve men affiliated with the Quds Force of Iran's Islamic Revolutionary Guard Corps (IRGC)
disguised themselves as U.S. soldiers, entered the Provincial Joint Coordination Center in the Iraqi city of Karbala, killed five U.S. soldiers, and wounded another three
November 2022: A captain in Iran's IRGC
orchestrates the killing of an American citizen living in Baghdad who worked at an English language institute.
October 7, 2023: Hamas
kills at least 48 Americans and kidnaps at least 12 Americans in a massacre of 1,200 people in southern Israel.
