What would motivate Germany to keep concealed actions which were taken AFTER the end of World War II? I can only imagine that the problem is that many in Germany continued to support the policies of the Nazis long after the end of the war.
Such support, which might include hiding Nazis in their sixties and protecting them from trial, could have been provided by people who today are only in their sixties. One can only guess at the level of criminality that such people engaged in in order to protect those guilty of genocide.
And today. Cults do not die out when their armies are defeated. Neither do they die out when their ideas completely fail, as in the Soviet Union.
Genetically, Germans are programmed to labor on a strange idea until it works well. Witness the Volkswagen Beetle from 1936 to 1980!
“I can only imagine that the problem is that many in Germany continued to support the policies of the Nazis long after the end of the war.”
Why do you suppose that it remains necessary to ban the NSDAP, to have a court continuously in session to ferret out and ban organizations and groups that print or discuss NSDAP ideas or create symbols or music that could be understood to relate to the NSDAP?
It remains necessary because they are damned afraid of the ghost of the Austrian corporal.
And well they should be. His ideas and his program, except (possibly) the antisemitism, fit the German psyche quite well.
