God literally punished them for falling away from Him with slavery and diaspora. It is in their own book you retard. The whole of the old testament is a literal cycle of them straying from God, being punished, repenting and asking Him to forgive them, Him doing so, then wash, rinse, repeat.
Yes, the Nazis were a punishment sent from God upon a sick world that deserved every second of it. Especially the jews, but not JUST them. We are past due. :blob_shrug:
