“They are, in many ways, a very self-apologetic, self-loathing people.”
Japan took the opposite approach, which was to ignore their WW2 past.
But who comes out ahead? Germany’s guilt has become suicidal-level where, in 30 years, they will either be a Muslim country, or they will have another bloodbath in their history to deal with. Japan’s only probably is their low birthrate - and no, it doesn’t take a civil war to solve it - it only takes turning back the clock so women can better be ‘encouraged’ to play their proper role in society.
We also allowed Japan to keep their emperor.
If we had done the same with The Kaiser after WWI, there would have been no Hitler.
