To add to the OP from the link:
For almost four decades, Iran and its terrorist proxies have targeted American civilians and military personnel. From the 1983 bombing of the U.S. Marine barracks in Beirut to more than a decade of attacks against U.S. military personnel in Iraq, Iran’s terrorist proxies have killed more Americans than any terrorist group other than al-Qaida. These attacks underscore Iran’s malign activities in the region and beyond. Congress and the administration must continue to confront Iran’s regional aggression and support for terrorism.
HOSTAGES HELD AT U.S. EMBASSY IN IRAN A group of Iranian students backed by Islamic Revolutionary leader Ayatollah Khomeini took control of the U.S. Embassy in Tehran, holding 52 U.S. diplomats and citizens hostage for 444 days.
MINE ATTACK IN THE PERSIAN GULF Iran—in violation of international law—mined the Persian Gulf. In 1988, one such mine struck the U.S. Navy guided missile frigate USS Samuel B. Roberts, injuring 10 sailors and blowing a 15-foot hole in the vessel’s hull.
TRUCK BOMBING IN SAUDI ARABIA Hezbollah terrorists—with Iranian backing and support—attacked U.S. military forces housed in the Khobar Towers in Dhahran, Saudi Arabia, killing 19 Americans and wounding 372.
SUICIDE BOMBINGS IN LEBANON The Iranian-backed terrorist organization Hezbollah—founded, armed, trained and funded by Iran—conducted two suicide bombings in Lebanon: the April bombing of the U.S. Embassy in Beirut killed 17 Americans and the October bombing of the U.S. Marine barracks in Beirut killed 241 Americans.
SUPPORT FOR 9/11 HIJACKERS Iran knowingly permitted members of al-Qaida, including several of the 9/11 hijackers, to transit Iranian territory on their way to Afghanistan for training. In April 2018, a U.S. judge ordered Iran to pay $6 billion to the families of 9/11 victims for supporting the hijackers.
DEADLY IRANIAN INFLUENCE IN IRAQ Iranian-backed Shiite militias in Iraq killed hundreds of U.S. service members and civilians. Iran provided training and material support for repeated attacks on U.S. personnel with conventional weapons and missiles, as well as sophisticated improvised explosive devices (IEDs) and explosively formed projectiles (EFPs).
OCTOBER 2018 UNJUSTLY DETAINING AMERICANS Iran has imprisoned U.S. citizens on spurious charges and without due process for decades. Former FBI agent Bob Levinson has not been heard from since he was arrested in Iran in 2007.
ATTACKS ON U.S. INTERESTS IN AFRICA Members of the IRGC in Nigeria were arrested for planning bombings targeting American- and other Western-affiliated destinations in the country.
HARASSMENT IN THE PERSIAN GULF Iran’s military has repeatedly taken a range of provocative actions against Americans in international waters, including charging American ships at close range as well as the seizure of two naval vessels and 10 U.S. sailors in January 2016.
ASSASSINATION ATTEMPT IN D.C. American law enforcement disrupted a plot backed by Iran’s Islamic Revolutionary Guard Corps (IRGC) to assassinate the Saudi Arabian ambassador to the U.S. by bombing a popular restaurant in Washington, D.C.
HEZBOLLAH PLOTS ATTACKS IN U.S. In June 2017, two Hezbollah operatives were arrested for conducting surveillance of U.S. military and law enforcement facilities, as well as airports, in New York City in preparation for terrorist attacks against Americans.
AGENTS OF IRAN IN THE U.S. In August 2018, two Iranian agents were arrested for surveilling potential terrorist targets in the United States, including Israeli and Jewish targets in Chicago.
IRANIAN PROXIES TARGET U.S. DIPLOMATS Iranian-backed terrorist proxies in Iraq launched attacks against the U.S. Embassy in Baghdad and the U.S. Consulate in Basra. The funding and training for these assaults came directly from Iran.
