And of course the press has well documented that we went to war not for reasons associated with national security related to weapons of mass destruction but due to policy decisions [T.D.S.M-2005, T.T.O.L-2005] which were presumably to make President Bush look good for his 2004 reelection campaign. It has also been documented that there isn't any "extraction strategy" [e.g. Krugman-2005]. The "coalition" conveniently forgot about that during the rush to war. The best the external forces can hope to do is train up enough Iraqi's whose choices of death would appear to range from being kidnapped and beheadeed, being dragged from ones vehicle and shot or being blown up in one of the less precise attacks by insurgents.
The data for this is from the Excel spreadsheet BushDeathToll.xls which in turn is derived from the military references cited.
