I’m back from a brief trip to Iraq that left me feeling awed, encouraged, and depressed. Awed because our troops and commanders are amazing. Encouraged because we’ve turned the tide in a lot of places, especially Sunni areas. Depressed because Iraq has slid so far in 2006 and because what we need for this ultimately to work–some form of Sunni-Shia reconciliation–is not entirely under our control. The trip was an education and made me realize just how much I–and most other commentators here at home–don’t know about Iraq.
