Splitting the Sunnis from Zarqawi has been a high priority for the U.S. in Iraq. But as in Tal Afar and other towns, it's difficult to have enduring success if Sunnis watch those who help us get assassinated and believe that Zarqawi's henchmen control the ground. Today's Washington Post story on Ramadi is not encouraging, especially given the progress we had made with tribal leaders. But it looks like the Marines, who've requested additional troops for many months, will get some more.

The U.S. military said Monday it was deploying the main reserve fighting force for Iraq, a full 3,500-member armored brigade, as emergency reinforcements for the embattled western province of Anbar, where a surge of violence linked to the insurgent group al-Qaeda in Iraq has severely damaged efforts to turn Sunni Arab tribal leaders against the insurgency. The insurgents have assassinated 11 tribal leaders in the Ramadi area since the end of last year, when Sunni sheiks in the city began open cooperation with the U.S. military. That alliance was heralded by U.S. commanders as a sign of a major split between Sunni insurgents and the larger Sunni community of western Iraq. The insurgent attacks since then have all but frozen the cooperation between Sunni tribal leaders and U.S. forces in Ramadi, local leaders say.... "We hope to get rid of al-Qaeda, which is a huge burden on the city. Unfortunately, Zarqawi's fist is stronger than the Americans'," said one Sunni sheik, who spoke on condition of anonymity for fear of insurgent retaliation. He was referring to Abu Musab al-Zarqawi, the leader of al-Qaeda in Iraq, an umbrella group for many of the foreign and local resistance fighters in Iraq. Local Sunni leaders often insist that the most violent insurgent attacks are by foreign fighters, not Iraqi Sunnis. In Ramadi, "Zarqawi is the one who is in control," the sheik said, speaking to a Washington Post special correspondent in Ramadi. "He kills anyone who goes in and out of the U.S. base. We have stopped meetings with the Americans, because, frankly speaking, we have lost confidence in the U.S. side, as they can't protect us." ...Marine officers on the ground have been open for more than a year now about needing more troops in Anbar, whose Sunni population, remoteness and comparative lawlessness have made it a stronghold for the insurgency. Anbar borders Syria, a conduit for some of the weapons, money and fighters.
