Cleric Moqtada al-Sadr and the Shiites in Iraq

Well it looks like anti-American Shiite cleric Moqtada al-Sadr thinks he is the leader of the Shiites. If this were true, which I think not, it would mean we have one leader to sit at the table to negotiate with. Now if they can produce a Sunni of similar fame and clearly leading the Sunni militia, we would possibly be able to negotiate. The real question is whether cleric Moqtada al-Sadr speaks for Iraq, Iran or himself. This should be apparent in the weeks to come.
