Well sir, the nuance you are neglecting is agressive invasion. "Preemption" if you will. The occupied Japanese and Germans knew their governments had engaged in very bad behavior, especially the Germans, who got to take a few sight seeing tours of the local death camps. The Japanese had been ordered by their God-emperor not to resist. Agressive war, on the other hand is an attack on a nation at peace. Name an instance where that has not resulted in a partisan movement.

Agressive invasion is an immoral act in and of itself and is considered a war crime absent justification, which so far we have none. As I stated before, "Waging Agressive War" was a crime that Nazis and Japanese hung for.

Immoral acts committed on people lead to a desire for revenge. Simple human nature. I'm an Iraqi, tending my goats. All of a sudden, my house blows up and everything that ever meant anything to me is gone. It would not have happened if you hadn't invaded my country without reason. I now hate you on a level incomprehensible to most people, and will spend my life trying to kill you. Human nature, pure and simple, and why "preemptive war" is a very, very bad idea. It creates people like this. They're planting roadside bombs as we speak.
