I have to agree about Pahlavi.
I think he could truly be the unifying force behind the democratic movement. And that's what it needs to get rid of the regime.
True. The regime has successfully bullied and eliminated anyone who could be a uniter. I believe they even propped opposition and took notice of their supporters, then embarrassed and discredited their puppet and successfully made it difficult for Iranian people to trust any emerging leader. With one exception, Reza Pahlavi.
