That happens when you kill millions of the most manliest men of their society in two world wars. Years ago on another website I used to ask why England seems to be more or less overrun with queers. One person who was very knowledgeable on military history said "Verdun."
Maybe losing millions of their best has gelded the center of Europe, but that doesn't explain Scandinavia. I'm pretty sure when they get fed up, that Viking mindset is going to reassert itself, and I think a bit of Militaristic Violence will always find a warm place in German's hearts.
The English, pound for pound, were some of the meanest bastards in history, during most of which they punched far above their weight class.
I don't think that stuff is gone, I think it's merely dormant, and about to be roused by these Nut-religion fanatics.
