'The grouping of Sunni tribal sheiks in the once al-Qaeda–infested western province turned against the insurgents and sided with the U.S. military, providing the model for what became a nationwide campaign known as the Sahwa.

If it happens, this time the lines in the sand will more likely be between Sunnis. Iraq's minority Sunnis have become increasingly split between those like Sheik Hamid, who are now allied with the Shi'ite-led government, and Sunnis who are against it.'
