Well at least you are wise enough to have your own opinion and realise your friend is wrong and I hope you will manage to convince him. Maybe he is having an attitude. It will be hard because he'll probably say Nuremberg was made up etc.. I wonder what he would say about Mengele? You can also check martyr places like Lidice or Oradour sur Glane and see the horrible things the Nazis did to women and children. If he still won't change his mind then he's sick.
