No Germans were hung at Nuremburg for crime of invading another country...
Perhaps I’m wrong, but I thought the principal charge at Nuremberg was, “waging aggressive war.”
I am sorry but you are so wrong. Do read some history, old chap.
eg: Wilhelm Frick: Guilty of planning and waging wars of aggression, war crimes, crimes against humanity. Hanged.
Hermann Göring: Guilty of conspiracy against peace, guilty of planning and waging wars of aggression, war crimes, crimes against humanity. Sentenced to hang.
Alfred Jodl: Guilty of conspiracy against peace, guilty of planning and waging wars of aggression, war crimes, crimes against humanity. Hanged.
Wilhelm Keitl: Guilty of conspiracy against peace, guilty of planning and waging wars of aggression, war crimes, crimes against humanity. Hanged.
