PRO: Suave and cool under pressure, he helped set up Iraq's government and get its constitution in place. Now he's moving to U.N. headquarters, where his dexterity in dealing with warring tribes should help him make sorely needed friends for the U.S.
CON: His success will ride on whether his bosses in Washington want to work more amicably with the U.N.
