Iran has not been attacking US civilians. This is nonsense. The best you're going to come up with there is the Iran hostage crisis. And what was that? That was when Iranian students stormed and occupied the US embassy, almost 50 years ago, demanding that the US extradite Mohammed Reza Pahlavi - the tyrant that the US had installed in Iran after overthrowing their government, who was then granted asylum after he was overthrown and fled to the US following events like the Jaleh Square massacre.

In the end 0 civilians were harmed and it led to the Algiers Accords [1] under which its chief provision is that the US would not intervene politically or militarily in Iranian internal affairs. Besides the US obviously endlessly violating that, we also violated another section of the treaty (related to the settlement of litigation) almost immediately after it was signed.
No they haven't. A proxy war is what we have going on between the US and Russia in Ukraine. You instead have autonomous groups, largely affiliated primarily by religion (like Hezbollah), that receive support from Iran. It's more akin to the situation with Saudi Arabia where extremists of their flavor of Islam, including Al Qaeda, often find material and personnel support. For instance 15 of the 19 attackers from 9/11 were Saudi.
And I doubt you'd call Al Qaeda a 'Saudi proxy' or 9/11 a Saudi-US proxy war. It's nonsensical.
