"These scenes you’re seeing coming from Iran…it is important for your audience to know the reason you see these scenes of confusion and chaos is these people have been denied their constitutional right for peaceful protest. Under Article 27 of the Constitution of the Islamic Republic, Iranians are entitled to peaceful protests and not even under the condition of so-called national security are they to be denied their constitutional rights. So it is really the custodians of the Islamic Republic who are in violation of their constitutional right rather than the other way around.

Roberts: The street actions as you see them, are they a revolution in the making as many people think they might be, or do you see them as something else?

Dabashi: No. On the surface of them, on the look of them, they are very similar to the events that were happening in 1979, the commencement of the Islamic Revolution. But in my judgment this is not a revolution. This is the closest thing that we have had in Iran to the Civil Rights Movement of the United States. So you have to zoom back and look at it — pull yourself back to 1955, Montgomery bus boycott and have a larger frame of reference. These people are not after regime change. All their protests are within the boundaries of law. Repeatedly, the leader Moussavi has emphasized they are only after their constitutional rights and they simply have lost trust in the way their elected officials or unelected officials are tabulating these numbers."

Of course, it' possible it could change.

The American Revolution didn't start with idea of becoming independent of England- it was only after the mis-handling of the situation by King George III that it developed into movement for independence.
Obviously, the Iranian regime is pushing it towards towards a revolution- the same way the King of England did.
Considering that they those guys are sort of crazy, it's possible they actually want a revolution- perhaps even a martyr's death and the end of the world sort of thing. Or they are simply acting like all the power mad dictators throughout history.
