Earlier quoted context omitted.
Nazi not punished ? Most of them died in the war. Oh and none of the allies war criminals were punished. You forgot to mention that.
Plenty of Nazi scientists and war criminals were given amnesty in the US after the war in exchange for their knowledge.
Let me remind you that ALL the Allies war criminals were also basically given amnesty everywhere, just because they were victors.
if you think that's fair, well that's your call.
