These things usually happen from within, not by external force. I'm thrilled that Ahmadinejad and the mullahs overplayed their card so baldly. As a result, they've lost "the street". Oh sure, they may be able to forcibly keep order for awhile, but the fuse is lit. No invasions or purple diatribes from here needed now. At this point in time (and, of course, this might change) I hope the US plays it like the New England Patriots scheme - - let the other team make the inevitable mistake and then pounce/take advantage. After this weekend, they are on their way down the drain.
