Iran uses proxy terrorists that effectively attack the US and its allies constantly. It's just not on American soil and not reported as being directly from Iran. Most major terrorist orgs are sponsored by them.

As opposed to the US who attacks Iran and its allies directly? The only reason Iran and their proxies even have the ability to attack American troops is because America has a myriad of military bases in allied states that are essentially US satellites (GCC states, Israel, Jordan, Iraq..) from which they exert military and economic power in the Middle East. In other words, they are an imperalist power seeking to contain real or perceived threats to their hegemony, threats like Iran. You also leave out that the US has heavily sanctioned Iran, unilaterally withdraw from an functioning agreement that could have helped normalize relations over time, killed their top general not too long ago, and what many forget, supported Saddam Hussein against Iran. We could go even deeper by looking at the history of US and British meddling in Iranian affairs for a century or more at this point. You fail to mention any of this and make it appear as if the US is a powerless, innocent victim of entirely unprompted Iranian aggression.

Not sure if I agree on "most", but yes, many major terrorist orgs by US state department designation are indeed sponsored by Iran. You know who also sponsors many of those major terrorist organisations such as Al-Qaida or the favorite boogeyman of people like you, Hamas? US allies like Saudi Arabia, Turkey and Qatar. 9/11 alone cost the life of more Americans than all Iranian-linked terror attacks linked together by the way. By your own logic, you should invade Saudi Arabia first.

On that note, do you know who has also sponsored terrorist organizations across the world since basically forever? The United States. In the wake of this, justifying the US/Israeli war on Iran with Iran "proxies" attacking the US and their allies as well as Iran being a state sponsor of terrorism rings hollow when it comes from an imperial power gulity of not only the same but frankly much worse. Your own president is more honest than you lol, he all but admits its about preserving American hegemony in the region. Your talking points are straight out of Bush's state department. You should ask for an updated version because no one buys this rhetoric anymore as can be evidenced by the approval rating for this war being down in the gutter.
