Whether they intervene is a big question, but I think it is unlikely because they will win against the US certainly if they continue the wait-them-out strategy, but they might not win if they militarily engage right now. Still, huge setback for them to lose such a great ally.... and yes Iran will be destroyed now that the US is involved... could be a long and brutal battle and many people will say America lost due to the long expensive war (but the insiders will wil of course), but Iran will lose too, big time.

Yeah I tend to agree. I'm thinking that Iran's best move at this point is probably to just keep smashing Israel. According to Trump this is all about nuclear weapons, and according to Trump he just destroyed their capacity to produce nuclear weapons. So there should be no reason for any further US involvement unless their true intention was nothing to do with nuclear weapons and everything to do with Israel and the SCO.
