Humanitarian war?
Also, the writer gets in wrong in asking if 1,000 US lives are a fair price to pay for ridding the Iraqis of Saddam. The real question sounds more like are 10,000 US lives a fair price to pay to rid us (Americans) of the inevitable risk we face if Saddam is left unchecked?
I hope that we would not invade Iraq just to "free" the Iraqis. That's their job. People get the leaders that they allow. Our job is to keep us safe. Any other benefit is icing.
