My sister lived and worked in Germany for a while in the mid-70's, she still has her German friends and contacts. I'll ask her what they say.
Myself, I have a feeling that Der Volk are hunkering down. I like the German people I know very much. I lived not far from Oradour where an atrocity killed all in the town save a handful (3 or 4 survived - they shut all women and children, including babies, in the church, machine-gunned quite a lot and then set the place ablaze and barricaded the doors.
Point is that a huge number of visitors were Germans, very solemnly educating their children about the horrors of the past and insisting that this must never happen again. This has been drilled in.
They are, however, also, normal people and may well feel that the sins of the fathers have been visited for far too long on the sons, grandchildren and great-grandchildren.
I am not to blame for the slave trade etc - my family were slaving on the land and in factories - so I wouldn't apologise for that. I think that a lot of Germans may be saying 'nichts mehr'!
