Political Chaos in Iraq

Yeah, Mr. President, this could hardly be going better:

Iraq's dominant Shiite political bloc fractured Sunday when its most powerful faction publicly demanded that the incumbent Shiite prime minister resign over his inability to form a unified government. The split came as Secretary of State Condoleezza Rice and Jack Straw, the British foreign minister, paid an urgent visit to Iraqi leaders here to convey in the most forceful terms yet that their patience for the country's political paralysis was wearing thin.

It was not clear whether the joint visit by Ms. Rice and Mr. Straw, the top emissaries of the two countries that led the invasion of Iraq three years ago, played a direct role in the splintering of the Shiite bloc, and whether that schism would lead to forward movement on forming a new government, which has been stalled for months.

The developments suggested that a new phase in Iraq's convulsions might have started by opening a possibly violent battle for the country's top job between rival Shiite factions, which both have militias backing them. The incumbent prime minister, Ibrahim al-Jaafari, has said he will fight to keep his job, and his principal supporter is Moktada al-Sadr, a rebellious cleric whose Mahdi Army militia has resorted to violence many times to enforce his wishes.
