It really does seem like this war of choice was[1] an absolutely boneheaded idea. It's the kind of thing (and specifically, the lack of consequences or measures to prevent it from being repeated in Cuba or Greenland) that highlights how broken American politics are right now.
1. Not even in retrospect - intelligence agencies knew this was a significant risk and I'd bet your average person on the streets would have come to the realization that it was a bad idea if they thought about it for like a week.

Closure of the Strait of Hormuz is one of the most modeled events in military circles. There are probably thousands of military exercises on it, intelligence estimates, strategic papers and so on. Up until this war, it was unknown if Iran could keep the Strait closed against direct US military pressure. Well, now we know.
There doesn't appear to be a single serious person in the US military, intelligence community or policy support organizations who thought this was a good idea. It was purely political. The administration seems to have listened solely to and relied entirely upon Benjamin Netanyahu and Mossad. Israel has been trying to get this war with every president since Reagan [1] and they've all said "hell no". Until this one.
What's more interesting is that it's been clear what a disaster this almost immediately so we've had ~2 months where it was clear that the US has militarily lost and a negotiated settlement was the only outcome. This would mean the end of economic sanctions and, for anti-Iran hawks in the US and Israel, a spectacularly worse deal than the JCPOA that got torn up. Yet the administration seems more willing to let the world ban than split with Israel.
