I hope he's telling the truth. I could care less if 1 million Iraqi civilians die. It would be 100% Saddam's fault, as they (in keeping with the main Islamic "religious" precept of "civilians are disposable on both sides") have chosen to use the Iraqi people as human shields.
Well, I could. We didn't go there to kill a million civilians. I trust the commanders on the ground to adjust the rules of engagement as necessary to handle a fluid situation. Civilian deaths are something we should try to avoid where possible. That doesn't mean we avoid them at all costs.
