Tehran already spent much of its proxy force in Lebanon however they still have a few tricks up their sleeve. I believe they'll spend everything fighting for the implementation of their Islamic utopia. The leadership in Iran is fascist… They've made too many steps in the direction of war to turn back now. They have to fight – unless everything they’ve said for the last 27 years has meant nothing. It cannot be ignored that their identity depends on conflict.
Iran can wargame and rant and rave about how powerful it is all it wants. It takes one state-ordered step beyond its own borders, and it will be utterly destroyed and occupied.
