Well, al-Maliki could pay the Sunni tribes not to fight and to resist and turn informant on the foreign AQI elements.
That is how we finally pacified Anbar Province when we were still there. Those fuckers hate al-Maliki and the Shia much more than they hated the US. I'm afraid some fighting is on the horizon and I hope we stay the hell out of it.
I am still waiting for a regional war to erupt over the Pan-Kurdish tensions that spans Syria, Turkey, Iraq and Iran. Again, another big mess waiting to happen.
