I learned recently that there’s a deep public disgust of US meddling in Iranian self-determination going back to the 50s. I don’t know how the public feels about Israel but I’m guessing it’s not popular. The people wanted change but I suspect there’s consensus “not like this.”
The regime has been decapitated and it lives on. They planned for this for decades and built a resistant decentralized command structure.
Their army survived the first shock and is now engaged in a decentralized gorilla conflict (as they always planned) and everyone knows how that ends. (When US gives up without accomplishing anything and goes away)
