The south is a mess too:

Britain hopes to quit Muthanna, and perhaps Maysan, this year, and Dhi Qar and Basra next year. As this week's violence shows, it will not be a glorious exit: nowhere in southern Iraq is the central government in firm control. Yet with so few forces to control so vast and vexed a region, the British have never pretended to be doing much more than paper over the cracks.
