Since you said: > Just pointing out it's difficult to call something a "crime" if there was limited legal basis for it (no international treaty) at the time. I can't help but wonder if you'd find it equally difficult if someone calls certain actions of the Nazis a crime -- assuming there was limited legal basis for it (no international treaty) at the time, etc. Or is it only difficult when we're talking about American crimes?
