I'm glad there's finally a coalition

But the coalition (is two nations really a coalition?) hasn't state regime change is the purpose of the war. Well, they did, and then changed their minds. Several times.

And, as I'm sure you're aware, knocking off the head of state in Iran doesn't necessarily move the needle on regime change. Dismantling the IRGC and removing the hardliners will be a long, dangerous operation and I doubt the US has the stomach for that. And Israel has already moved on to bombing Lebanon again.
