Most of its public administration was rebuilt after the war with the same Nazis in high functions that held them during the Holocaust. And Germany have done insultingly little to clear out these roots

If people confuse historical responsibility of a nation state with their own personal responsibility then that is exactly the kind of dangerous nationalism that leads societies straight back into fascism.

Holy shit dude. No! Absolutely not. Germany today is the result of its history and that needs to be a part of and discussion involving it.
