The German history is a very complex one. Some habits in society and in families are going back still to the 30 year war, which was an extremely cruel one. Germany inhibited psychological pain over centuries from wars, battles, restrictions and cruel upbringing practices. Keep in mind, Germany didn't exists as a country before 1871 (!). It were "smaller" states like, Schleswig, Pommern, Preussen, Bayern, Franken and many more, all loosely scattered around, having big nations like France, the Nordics, Russia, etc. as neighbors, that regularly invaded some of the German states. That seeded a constant type of fear historically and resulted in a psychological overreaction over the recent centuries, certainly starting with the "Kaiserreich" from 1871 on, which encouraged strong but willing people that obey. The first World War is a complex and cruel situation in its own, but with roots in the European situation of this time, leading to the second World War where Germany played a very cruel role, but psychological determinable. In the 50s, 60s, the "Wirstschaftwunder" draws a typical compensation pattern of a wounded narcissistic personality from a psychological perspective. Parents buried a lot of pain from the past wars inside them, inheriting this pain to it's children, by being distached or "cold". Until today !, younger Germans suffer from this inherited "pain", they cannot explain, because not many looking at Germany's history and can connected all the pieces together. On the other hand it is fantastic what German overcame and became now. Overall Germans did a good job in the recent history, but I think they still can do better and should be more friendly to themselves. Accepting that the cruel German history starts waaay earlier then WW2.
