After the Bush-Maliki Iraq Summit, is Anyone in Control?

Today's New York Times quotes sources it says were part of the Iraq Study Group's deliberations on what to do next in Iraq. The bipartisan group will report its unanimous conclusions to President Bush next week. The Times says it will call for aggressive regional diplomacy, including direct talks with Syria and Iran. Rather than set a timetable for withdrawal of American troops, it will call for a gradual pullback. After his meeting today with Iraqi Prime Minister Nouri al-Maliki, the President seemed to reject a "graceful withdrawal" in advance. Meantime, al-Maliki faces the breakup of his political coalition. Former allies say they won't return to the government until he sets a firm date for US withdrawal. Is Maliki still running the country, or is anti-American Muqtada al-Sadr taking control? What should the US do?
