A lot more pain, if you ask me. The scary part is that all those who are arguing for an externally forced regime change talk about it as if it is a guaranteed thing. IMO people are only thinking of the best case scenario. but a war could go in many different ways and most of the possible outcomes could inflict a lot more pain in the people than they are experiencing now. Here is my worst case scenario: They bomb for some time and realize what we all know. Namely, you cannot do regime change from the skies. By this point, I would estimate thousands of innocent people dead already. So, then it will be time for boots on the ground. USA will not do this. It is the last thing Trump wants to get in. Israel does not have the man power. So, the only option left will be arming a bunch of people and starting a guerilla war that quickly expands to a civil war, if Russia keeps Sepah together. By this point, we have tens of thousands dead and most of the country's infrastructure gone. After this point we will reach a steady state stalemate where essentially different groups are controlling different parts of the country with well over hundreds of thousands dead.

We are then looking at Tajziyeh. IMO, this is the real Israeli objective. Not regime change.

I am not sure regime change was ever on the agenda. People wanted it to be but that was wishful thinking. Then there are people in the west that use regime change as a scare crow. If you are after regime change, you first hit the leader which they never did.

This has been my issue: the gap between people's expectation and what the US actually wants to do.

I also agree that negotiations in reality is pointless. They already had an agreement much better than what he will get now. But he threw it away. If they are actually negotiation for no nuclear weapons, IRI will gladly agree to that and that is what they have been promising all along. So, Trump has achieved nothing! This is either a ploy to surprise IRI with an attack or a Deal that Trump can say is much better than Obama's deal! Sad
