In case you missed Thomas Ricks's op-ed:Ricks wrote two terrific books on Iraq while covering the warfor the Washington Post. His sources are mostly military, and/but he raises some issues that have dropped from the discussion--like can the Iraqis stave off civil war without a serious U.S. military presence beyond this year. I myself have often wondered about the Kurdistan issue, but clearly there are many more loose ends, which he points out.
