See my post above. This isn’t about Musavi. Musavi is only short-term. If they succeed (far from granted) in ousting Ahmadinejad, they will go after Khamenei. Musavi will have to respond to their will, and this means opening the country, improving the economy, relations with the outside and no wars.
The people protesting are tired of wars. Iran had the 8 year Iran-Iraq war and a Government depending on the support of these people won’t be able to continue the warmongering politics any longer.
What I am afraid of his a lame deal between Musavi and Khamenei. He may decide to dump Ahmadinejad but to save his ass. I hope the people won’t fall for lame compromises.
Mousavi is the “Kerensky”, a transitional figure.
