Since unlike you he learns ... he understands that the Germans and Germany then under Hitler is not comparable to the Germans today, that the Italians are no longer Romans, that ... and here you can take whomever you like - nations, peoples can change and are no longer what they have been before.
And in the same way you need to stop believing the Russians - to admit Russia - today is no longer the good fellow who helped saving Europe from the German Nazis, but itself became a dangerous imperialistic and IMO almost Nazi-like country aka NOT GOOD!
As such, why should an Israeli or Jew today still hate the Germans today?
But for you this is surely beyond anything to comprehend.
By the way, so much on the latest proposals by a Russian genius to win the war.
