From Israel's perspective there's an even stronger self defense argument given the amount of missiles aimed at Israel from Iran and the enrichment of nuclear material to military grades while constantly threatening the elimination of Israel. So the US argument that they knew Israel was planning the attack and they knew Iran would retaliate against US interests seems at least on the surface to bad valid.
What the US claims is really not a strong source of anything, and I'm saying that as an American. The most compelling reasoning is that Israel was going to do something so US decision makers decided joining was the best worst decision, and I'm being very bend over backwards generous with that. Anything else is just excuses trying to cover it up. It seems obvious now that there was no stopping Israel from their strike on Iranian leadership. It was too ripe of a target, they have been emboldened by current US admin, so at that point it was in for a penny, in for a pound mentality.
If the US thought an Iranian retaliation from an Israeli strike would be to attack US assets, then the world would possibly have some sympathy. No rational person could condone an outright first strike just because we thought something was going to happen. Yet the fact that in the "we think they will do something" spit balling never suggested shutting the down the strait seems very suspect as well.
A reasonable belief, because Iran in fact responded to the US+Israeli strikes by attacking US allies and even neutral nations like Qatar.
And why should we doubt that Iran would have closed the Strait of Hormuz even if the US had not attacked, leaving Israel to attack alone? The strategic calculation (threaten the world economy so other nations oppose the war) would have been the same.
The largest US base in the region is an air base in Qatar (which Iran has hit).
Iran has attacked the US base in Qatar before. When they did so in 2025, Iran's Supreme National Security Council issued a statement: "this action does not pose any threat to the friendly and brotherly country, Qatar, and its noble people, and the Islamic Republic of Iran remains committed to maintaining and continuing warm and historic relations with Qatar".
This time Iran attacked Qatar itself, including the Ras Laffan gas facility and Hamad International Airport.
Iran has supported a treaty on elimination of weapons of mass destruction in the middle east, Israel has been the blocker of it, only actor in the region that has nukes, and isn't in the NPT.
As a non-signer of the NPT, military aid to Israel is also illegal under US law, so we play along with strategic ambiguity and pretend they don't have them.
An aggression is an aggression.
As in tribunals, to claim you acted in self defense, you need proof.
And the Pentagon itself admits there were no threats.
On who?
In 1992 there was a deadly car bomb attack in Argentina, killing 29 people and injuring 250 more. Then again in 1994 a Jewish community center in Buenos Aires was bombed, killing 87 people. Eventually the investigation demonstrated conclusively that Iran was responsible.
Albeit Hamas has been largely propped by Israel itself and Qatar.
I think you're simplifying quite a bit. And you're also omitting Israel and other near east countries or groups as a proxies of USA, simply by avoiding a clear and sensible non-discriminatory definition of what a proxy is.
Eg. USA's Israel "proxy" crucified (literally) a "Palestinian Christian poet, advocate of non-violence and PLO spokesman" in Lebanon and executed a random woman who stood in the way of their operation. This is one of hundreds a lot of the time political assasinations IL did all around the world.
Also Iraq attacked Iran during Iranian revolution in the past. You can hardly call Iraq a victim of Iranian proxy warfare.
You can't ignore history or the long-term USA and Russian meddling in the region.
Seems like significant subset of what you call proxies are locals who formed a group and tighter (Hezbollah) or very loose and inconsequential (Hamas) alliances with Iran, in response to either beligerent occupation/aggression or invasions by some other groups like Israel, Iraq, Saudis - basically in response to wars fought over land and resources.
