Elon Musk tells Germans to "move on"! [247]
This gradually grew into both a deep resentment of foreigners telling them what and how they as Germans should have acted. Later on, it developed into a sort of "empathy fatigue"
...that sounds rather human. Natural human reactions....but it must be said that wasn't a continous thing for all to all times.
As the Cold War startet the western allies needed the western Germans and toned down all that.....the same happened in the East. The Nazi crimes and the punishment for that faded into the background of actual politics.
As was mentioned already....it had been the "roaring Sixties", the 68er youth rebellion (if you call it like that), the next generation, which had nothing to do with that, which started to bring it to the forefront again and pointing fingers at the many ex-Nazis in gov and society....also only in the West that ist...in the East it was not much of a topic for forty years at all (especially the Holocaust that is) besides the glorious victory of Communism over Capitalism.
As I remember it became a big topic again in the course of the re-unificaton of West and East.....mainly stemming from fear of a to-strong Germany again...and unresolved reparation questions and re-negotiated borders and such...and here we are!
