Protests in Iran, today and thirty years ago

Since the disputed presidential elections in Iran over the summer, there have been a series of protests, the latest, on Sunday, ending in at least 8 fatalities. How does today’s unrest in Iran compare � if it does at all � to the demonstrations which preceded the Iranian Revolution 30 years ago in 1979? We talk with Baqer Moin, the former head of the BBC Persian Service, and Hamid Dabashi, a professor of Iranian studies at Columbia University, about whether the country is headed for another revolution.
