Even nazis dont qualify as war criminals just by being nazis. The ones who we find guilty actively gave orders rather than just following them. The reason is the same, much like people have to eat and work you'd get shot and killed if you stood up against your commander int he nazi army.
@cuibonobaby Thats not what im saying.. what im saying is even nazi's werent found guilty simply for having hitler as a "boss"
@freemo In fact, during the denazification process in Germany people were denied jobs just for being members of the party.
