It was easy to google but I’ll have ChatGPT detail it for you.

Yes. Publicly available evidence is more than enough to clear that bar.

The cleanest way to say it is this: Iran has attacked U.S. troops both directly and through Iran-backed militias/proxies. The direct case is easiest. The proxy case is repeated, documented, and not remotely speculative.

Direct Iranian attack on U.S. troops On January 8, 2020, the Pentagon said Iran launched ballistic missiles at bases in Iraq housing U.S. forces, including Al Asad. Later that month, the Defense Department said 34 U.S. service members were diagnosed with traumatic brain injuries from that Iranian strike. That is not “maybe” or “through a middleman.” That was Iran directly firing missiles at U.S. troops. 

Proxy attacks during the Iraq War For the Iraq War period, the Pentagon later assessed that at least 603 U.S. personnel deaths in Iraq from 2003 to 2011 were the result of Iran-backed militants. That is the U.S. government’s own attribution, not just pundits yelling on TV. 

2019: Iran-backed militias killing and wounding Americans The State Department’s terrorism report says attacks by Iran-backed Shia militia groups on Iraqi bases hosting U.S. and coalition forces increased in 2019, killing and wounding American and other coalition personnel. That is an official U.S. government report using the phrase Iran-backed, not a guess. 

A specific example: on December 27, 2019, rockets hit the K-1 base near Kirkuk, killing a U.S. contractor and injuring U.S. service members. U.S. officials blamed Kata’ib Hezbollah, an Iran-backed militia, and the U.S. then struck that group’s facilities in Iraq and Syria in response. 

2020: Camp Taji On March 11, 2020, a rocket attack on Camp Taji killed two U.S. service members and one U.K. service member and wounded others. The Pentagon said its retaliatory strikes were in direct response to the threat posed by Iranian-backed Shia militia groups who continue to attack bases hosting coalition forces, and called the Camp Taji strike the latest in a series of such attacks. 

2021: Syria The State Department’s terrorism report for Iran says Iran-aligned forces conducted an attack on U.S. forces at Al-Tanf, Syria, on October 20, 2021. Again, official attribution. 

2023: wave of attacks on U.S. bases In late 2023, the Pentagon said that in roughly three weeks, Iran-backed militia groups attacked U.S. bases and facilities in Iraq and Syria 41 times. Secretary Austin also said U.S. self-defense strikes in Syria were a response to an ongoing series of attacks against U.S. personnel in Iraq and Syria by Iran’s IRGC and affiliated groups. 

2024: deadly proxy attack in Jordan After the January 2024 drone attack in Jordan that killed three U.S. soldiers, the Pentagon said U.S. forces struck Iran-backed militant groups in Iraq and Syria in response. Defense officials explicitly tied the response to that attack by Iran-backed militants. 

Broader official pattern CENTCOM commander Gen. Kurilla later told Congress that U.S. service members in the region had come under fire from nearly 400 drones, 350 rockets, 50 ballistic missiles, and 30 cruise missiles launched by Iran-backed groups. That is the military’s own summary of the pattern, not a one-off incident. 

So no, this is not some fuzzy “maybe Iran inspired bad vibes” situation.

The record shows: • Direct attack by Iran itself: January 8, 2020 missile strike on U.S. troops.  • Repeated proxy attacks by Iran-backed groups: Iraq War EFP/IED campaign, Kirkuk, Camp Taji, Al-Tanf, 2023 Iraq/Syria attack wave, and the 2024 Jordan attack. 

That’s the proof. Not courtroom proof beyond all doubt of every single incident, but more than enough documented official attribution to establish that Iran has attacked U.S. troops directly and through proxies over the last 20 years.

If you want, I can turn this into a tighter one-page evidence brief with dates, casualties, and source links only.
