First, we will not achieve any goal in Iraq, as we have demonstated quite successfully elsewhere...the war will drag on, a puppet government of sorts will be set up, we will become disheartened and go home and watch the house of cards fall. However if we stay long enough, we can kill as many as we did in Vietnam, and then go home. Maybe we can be as successful as Cambodia and kill a third of its population. The difference between ourselves and cavemen is the number of people that we can kill at one time...Neolithic people were very inefficient, killing one by one, now with advanced technology, hell we can kill hundreds, thousands and with the big toys even millions quickly. Is it justified? Certainly not! The people that make the wars don't fight in the wars now...there's no George Washington leading the troops, and if you see the fortifications on a general's house in Iraq...reminds you of Fort Knox. They don't suffer the heat, mud, flies and thirst. They don't get shot, and they don't see dead babies, old women, school kids mutilated. Everyone hears the horrors of 9-11....an instant in time....but these people face this everyday...all day....is it justified?
