Okay, I believe we are talking past each other, because you really are not refuting my central argument and I do not believe I've stated it well enough.
Nazism was a swirl of what the world has, since WWII, been referenced as the worst humanity has to offer for a number of reasons. In the West, they were told that starting the war for land acquisition, their ordering of society, and their extermination of peoples according to that order were horrible. In the East, they were told that violent opposition to the Dictatorship of the Proletariat was evil in equal measure. From the Communist perspective, the worst the world had to offer.
This was not some colonial backwater of a nation. This was not a monarchy that lost a border dispute. These were a proud people on the edge of unrivaled imperial glory at the start of the 20th century with the finest military on planet earth brought very, very low.
So after 1944 and 1989 in particular they've had to think about how they want to reorder things and, unfortunately, a lot of the lessons they seem to have learned emerged from Western liberalism/multiculturalism and the idiotically vague charges of the Nuremburg trial. They've largely concluded that national pride and war-making are evils in and of themselves. That narrative is very compatible too with what the Soviets slapped them into believing in the east. I think this is a very logical explanation for why the Germans have responded the way they did.
But I've never lived in Germany and as a person of German Jewish extraction, I'm more likely to focus on the impact of Nazism and the Holocaust. But please! Tell me why you think Germans are particularly pacifistic and rather unpatriotic these days and why this all so happens to coincide timing-wise with the aftermath of WWII and decades of division during the Cold War.
