Notice that all you need is to invoke the name of Muqtada as-Sadr and refer to his stay in Iran, to dismiss and discredit the "tens of thousands" who protested: "A day after Defense Secretary Robert M. Gates suggested that American troops could remain here for years, tens of thousands of protesters allied with Moktada al-Sadr, the radical anti-American Shiite cleric, flooded the streets demanding an end to the American military presence.
The protests were scheduled before Mr. Gates’s comments — made on Friday during a visit to troops in northern Iraq — although his statements may have fueled some of the day’s fervor. The protesters were whipped up by comments drafted by Mr. Sadr, who is continuing his religious studies in Iran but who sent a message to the crowd threatening to reconstitute his militia, the Mahdi Army, if the American military did not leave this year. “The first thing we will do is escalate the military resistance activity and reactivate the Mahdi Army in a new statement which will be published later,” Mr. Sadr’s representative, Salah al-Obaidi, told the crowd. “Second is to escalate the peaceful and public resistance through sit-ins.”"
