I saw a soundbite just now on CNN by the head of the joint chiefs of staff concerning Iraq not fighting a lawful war by placing weapons near civilians and mistreating POW's. It's war, bubba, what do you expect? They are using strategy which you use when you are faced with an overwhelming force. Remember the Vietcong? They mistreated POW's and used villages as supply bases.
I'm afraid that if the populace doesn't accept the American presence as a liberation we could be in a messy situation. If the population doesn't accept you then the only way you can win is by destroying the infrastructure of the country like we did to Germany in World War II.
Just a thought I had.
