Look at Lebanon, seems to be working out with Hezbollah being slowly ejected from political apparatus and disarmament. This would be unthinkable even a year ago.There is no moderate or secular without also being western worshippers. That doesn't exist in a country like Iran. Islamism is not just about religiousity in a country like Iran, its also political. You can't kill the hardliners and bring moderates into power. When hatred is created, it only creates more extremism, more motivation for revenge.
After getting hit like this, can self-respecting Iranians say, yes, let's worship the west more. Nope. Anyone moderate will be sidelined as traitors. Even more hardliners will gain power.
You can't chant death to America if you get hit by a laser guided bomb.
