Rumor is Larijani wanted a more moderate Supreme Leader and didn’t support Mojtaba.
Also I think his own hubris got to him thinking that having his daughter in America meant something and the Americans NEEDED him.
Too intelligent for his own good
USA ruling elite doesnt need Eurasia.
The more disorder in Eurasia the better for USA ruling elite interests.
It seems nobody wants to see it, neither vassals, neither even Iran.
USA ruling elite doesnt need so many slaves. The larger number of slaves, and the richer, the worst for USA interests, more energy and raw materials wasted in them.
Iran war is like tariffs, but in a stronger way, a way to spread economic mayhem and shrink economies.
Every time I see a USA vassal or enemy believing USA needs them for something, it's ridiculous AF.
If USA would need something from them, they hadn't started this war in first place.
BTW Larijani behavior is not too intelligent, it's too arrogant and vain, typical in ruling elites.
They could believe they are needed because they important in their own country, but for USA ruling elite: protected by two oceans, and with the only concern of China and raw material/energy supply, they are nothing at all.
