Even if Trump doesn't care, Israel is very motivated to make regime change happen. They want to be permanently rid of Iran's nuclear threat, its funding of terrorist groups, all of it. Honestly I think Trump or at least his administration is on a similar page, and if not the Israelis can clearly be pretty persuasive.

No, my worry is whether it will be a regime change that benefits the Iranian people or some kind of sick puppet state. But of course:

> Trump will declare it as a victory regardless of what happens

...This goes without saying.

Edit: worth noting the Arab states tend to hate Iran as well, and Iran has already sprinkled some ballistic missiles on them just in this war. They're not going to speak up for Iran unless they think the escalation is getting too dangerous for themselves.
