One is "Do you agree with the decision to go to war?". I'd ask that you really be honest with yourself about what the real thoughts at the time were regarding Iraqi WMD. As I recall, everyone was extremely concerned about the possibility of war BECAUSE of the threat of chemical and bio weapons. But, aside from that even, read this: http://www.cnn.com/2008/WORLD/europe/11/20/sbm.bosnia.holbrooke/index.html And when they talk about these people, replace them with Iraqi's and Kurds in your mind.
Now, that then brings up the second point "Did we bungle this operation in a criminally negligent way?" I'd say yes, and Rumsfeld should pay dearly for this. He was the one who spearheaded the tactical direction of the war.
I think it's very fair to argue that we screwed this war up in ways that we'll be paying for for a long time. And I think our poor execution has done more to negatively impact our overall objectives in going to war. However, should we have gone in to begin with?
I think yes.
