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.
Are there any credible signs of this?
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.
I feel about Iran war the same way: yes it's going to happen whether we want it or not, there's nothing we can do. If you persuade everyone to not interfere, Iran would just drop nukes on other countries, so there will be nothing to interfere into later.
Saudi Arabia always declared that if Iran gets nuclear, they will do too, and they have unlimited money to do that.
For whatever you feel about WMDs or the justification for the Iraq war, the facts are we spent almost two decades in the first go round, found no WMDs, killed a dictator we installed, blew up a shit ton of infrastructure, rebuild a shit ton of it, killed probably millions of innocent people, absolutely blew up the Taliban and later ISIS's recruitment numbers, made ourselves look fucking stupid on the global stage, then pulled out, leaving billions in military materiel to be claimed by the people we were ostensibly there to stop.
An utter fucking farce, and we have learned absolutely nothing. Time to send more young men to die.
