You have too little faith in us and too much faith in the media. Have you seen those troops in Afghanistan and Iraq, have you watched the miracles they have worked with the people? Who do you think produced those fine, brave warriors? Who do you think taught them those values?
I've served in the military myself, and although I can state with first-hand experience that servicemen aren't angels, they are far above the average civilian.
I am also reasonable sure that, whether or not Bush is reelected (right now I think he has about a 51% chance), they will come home to a population that will be neutral at best, and hostile at worst. Women don't even like men in uniform any more.
