I generally agree, I don't think they anticipated a war in the Middle East and it kind of blindsided them. Israel is also strategically important to US, so they can't just let them hang like they're doing with Ukraine. On the other hand, US i starting to realize that Israel is a geopolitical albatross around their neck. It ruined the whole narrative they had going with Ukraine, and people around the world are increasingly turning both on Israel and US for sponsoring the very blatant and obvious crimes Israel is committing completely unapologetically.

I get the impression that US admin did not anticipate the political blowback for supporting Israel initially. Biden basically gave Israel a blank check at the start, and Netanyahu is now cashing it in because he knows that if the war ends his own position is going to be shaky. It's really not clear how much leverage US has over Israel at this point. US created a monster that's now biting the master's hand.

Until they can bring Israel to heel though, there's little chance of US actually having the capacity to get involved in other conflicts in my opinion.
