Withdrawing to Syria

Mohammed at Iraq The Model sees evidence of Sunni insurgents decamping to Syria to sit out "Plus Up." A good sign? An ominous sign? We'll see. If the surge works in the short term because its targets have simply gone into hiding, could that provide a window for Maliki to gain traction? Or does it simply mean postponing the battle until U.S. forces have withdrawn? Are U.S. forces going to achieve some success against Sunni insurgents before handing over the rest of the job to the Shiite government? I have no idea. Plus Up begins in earnest in a week.
