think big and matisyohu28,
ABSOLUTELY !!!! I would put a bullet through every cursed nazi I oculd and so did many of the fighters in the war. You are indeed correct in saying that there is still a reason to kill the enemies of our people. And matisyohu28 can assert that the nazis were spiritual descendants of Amalek, again, true. My point was that if you would meet that person today, without knowing his background , you could not have that mitzvah today.
Clearly, if he is a murderer and enemy , you would have to kill him, because of “ubiartu horoh mikirbecho”.
if you insist that Rav Kaniesky knew/knows that his soul was from Amalek, I’ll agree to this. Actually, this whole story could be easily verified. Was there indeed such a room of Nazi paraphenalia? Or wasn’t there? Just have the actual person coem forward and I’ll be happy to accept the story. As said previously, if there are reliable witnesses, sure, you should believe.
