Wrong. Like I said, it was pre-emption if he hadn't yet acquired WMD. Additionally, it was prevention if he had them already and we didn't give him the chance to use them. Also, it was moral to take him out on non-WMD grounds and strictly on humanitarian grounds. That's the way it is. Kant you underestand that?
I suppose if you evade the humanitarian disaster that we are directly responsible for, then you might be able to convince yourself to believe that for a while.
