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.
Okay. This was after we took in the Shah and they sincerely believed we were going to try to put him back into power. When the Shah died, they returned the hostages. NEXT.
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.
This would be AFTER we armed, supplied and supported Saddam Hussein's war of aggression on Iran.
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.
Actually, Al Qaeda did that, not Iran.
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.
We shouldn't have been in Beruit. Next.
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.
This is a plain, outright lie....
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.
Um, yeah, that's what happens to spies. We are currently holding two Iranians on charges of being spies.
Two arrested for allegedly spying for Iran in U.S.
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.
These would be sailors who ignored orders and crossed into Iranian waters..
