The problem I have is, I have less than zero faith in Zion Don and the Israel gang to engage in meaningful regime change.
The Ayatollahs and the mullahs should be drowned in the desert they've made with their bullshit. But the problem is, after getting rid of them, Iran still needs good leadership that actually tries to improve the country; as well as a removal of the whole basij system, the morality police and all that shit. Something which I highly doubt the US or Israel give half a damn about.
For Israel, it doesn't matter if the new regime is competent. In fact, it's a boon if it's incompetent, because it means it'll be unable to stand up to Israel if they try some shit.
For 80-year old King Joffrey, I highly doubt he gives a fuck what happens, so long as he ends up looking big and strong and good. If he could pull it off, I have no doubt he'd do a "standing in a flight suit on a naval carrier with a 'mission accomplished' banner" maneuver like Bush did.
