The Equation Shifts?

Goldfarb thinks so:

The left, which may have reviled Ahmadinejad but was willing to do business with him anyway, seems to have become deeply hostile to any kind of diplomacy that could be seen as legitimizing this election result. The administration hasn't quite caught up to this reality, offering weak statements about "irregularities" in the voting but no real sign that it will stand up and support the Iranian kids who are pleading for help as they're beaten in the streets. I suspect it will soon.

But what if the regime falls? We still have no idea what's coming next.
