I don’t get it. Didn’t the mullahs pick all of the “candidates”?. Mousavi, Ahmahdangnutjob...what’s the diff?? As for the protests, that’s like protesting you got Hitler instead of Mussolini. I can understanding Iranians protesting. They’ve got a lot to be furious about. But are they protesting the fact that their election was a crock, or that they didn’t get the despot of their choice? Color me confused.
In theory, a more open and free society would eventually back down from a more aggressive foreign policy, so Mousavi is better for us in the long term. But he's no angel; he's a thug bastard from way back, with a long bloody history within the government.
So, the differences are cosmetic in the short term, but may be pronounced in the long term.
