The three dozen countries supporting the United States in Iraq have between them deployed some 26,500 troops, a snip compared to the United States' 130,000: but their withdrawal would be a huge political blow to President Bush

Despite Iraq's spiraling violence, its U.S.-led occupiers insist the transition to democracy they have planned is the best thing to happen to the country for decades. And with three months to go until the transition begins, they hope a $5.8 million advertising campaign will help convince Iraqis they are right.

U.S. efforts to arrest firebrand Iraqi Shi'ite cleric Moqtada al-Sadr could spark a wider Shi'ite uprising and undermine Washington's control of Iraq, analysts at two military schools warned April 6, 2004. Sadr, 30, a radical cleric with tens of thousands of followers, was holed up in his office in the holy city of Najaf with armed supporters on Tuesday. U.S. officials have vowed to arrest him on a warrant for the killing of a Shi'ite cleric last year. Sadr's group has denied involvement.
