IMHO
1. Israel can't annihilate Iran. Examples of countries that could be annihilated with arsenals other than those on the permanent security council are "countries" like Andorra, Monaco, Singapore, Brunei, San Marino (aim for Fecal's boat) etc.
2. Most of Iran isn't crazy. The rulers are, yes, but the populate are probably more amenable to being bros with the West than basically all their neighbors. Look how pissed they got over one tourist woman basically taunting the old geezers the way our tourists take buffalo selfies and sh!t.
3. Respectfully disagree that Israel has minutes to live when Iran gets n00ks. Iran has a bunch of ancient fossils and there was unrest very recently and I doubt the "little people" have forgotten. That retaliatory strike was very carefully choreographed and telegraphed IMHO to be easy to intercept. That was about saving face internally, not punishing Israel for crossing a line. I'd wager good money people in Iran discussed the entire thing with the Brandon dildos, and this was about as "real" from Iran's side of the equation as a Jake Paul fight.
I don't think the Iranian military would act on an order to launch.
Personally I'm more worried about Pakistan v India boiling over than Iran v Israel.
