Not sure who you are talking to with this comment. Is your Dove/"think of the children"/Kumbaya singers routine just a strawman by which you can dismiss those critics of the war? Cause I'm hardly a dove and avoid using "think of the children" phrases like the plague. My comment you quoted was a normative statement addressing where the 650K casualty figure came from. Casualties associated with Saddam's reign are a different study.
As I stated to Marlin, if you defend the war and occupation as a humanitarian mission, so be it. But I question the legitimacy of those who claim this as a primary or even significant consideration in their support for the invasion. It strikes me as nothing more than a post-fact rationalization. A rather straight forward test of this would be to ask if the person holding this "Iraq is justified on humanitarian grounds" belief was also in favor of unilateral Rwandan and Darfur intervention.
