I was living at Fort Lewis when Lt. Watada refused to deploy to Iraq because he sincerely believed it was an immoral order. The brass fucking destroyed him. The troops on the line really don't have a choice. Not only is "just following orders" part of the separation of powers, it's not practical to resist when it will get you in just as much trouble as if you had participated in a war crime. It takes exceptional courage, and a belief that you're fighting for something more important than your own life, to make that moral stand. I salute those who do, but I don't condemn those who can't. The alternative is an army that not only enforces the law, but makes up their own rules as they go. And that's when things get really ugly. The Nuremburg principles aren't some magic pass that excuse you from following any order that opposes your values, all they really do is make it clear that you can't escape responsibility for obeying an evil command. Unless you win, then you get to write your own version of history.
