There is no backing down now. It is reported that the chief of staff of IRIAF is likely dead.
Most likely US Patriot batteries taking out Iranian ballistic missiles
Iran has a paperclip Army,it cant do shit.I don't see the persians doing much. Last thousand years it was Turkic power that gave that nation any strength. You take that out the picture and you return it to the middle eastern persians and these ruling class Khazar Turks will make a complete mockery of them.
I suspect Isreal will bomb the shit out of select locations, take out a certain number of persian top brass. The iranians will launch a few meaningless missiles and its back to talks again.
