I can't give you a prediction with timing either, because Israel would have to claim that Iran had rebuilt its facilities for the US to get pulled back in again, and an outsider has no way of telling when they would choose to do that.
Iran already knows that Israel can decapitate them at will, but not occupy them. Nothing has changed with these strikes.
Bombing nuclear facilities and killing scientists kicks the can down the road and that has worked for decades. But the US/Israel coalition is also trying to negotiate or orchestrate regime change, which could provide a more lasting impact.
Every respected strategist said the exact same fucking thing about Iraq before we killed 17 years there. Didn't stop us from trying and failing.

There is, of course, a lot of pressure for him to resign or for various other things to happen that he is currently managing to put on hold due to the war, but that's legal, and doesn't require wartime.
Absent all that, he faces elections in 2026.
This isn't even to say they are individually imperialists, but every last one, as soon as they take the oath of office, immediately begins getting their hands soaked, drenched in blood. They can't not. That's what the system does and that's all it can do. And the few candidates who ran on the idea that that should be changed were roundly rejected by their associated party, and an independent has received, at most, 5% of the vote?
Nah. Trump was never going to see anything, even for his particularly egregious offenses. I knew it in 2018 and I still know it. If he ever faces the most meager iota of consequences I'll eat my favorite hat, and post video here.
