Oh, I'm not saying that's your stance, but PPQ Purple's.
As for the guilt: your misgivings are understandable, but as far as I've seen, war guilt, or at least acknowledging German responsibility for the atrocities, is sincere and deep-rooted in German culture at this time.
True, for the first two decades after the war, Hitler maintained fairly high approval in Germany and Nazism was all too often seen as a "good idea, poorly implemented." This began to change with the new generation of the '60s, which asked the older ones why they were so quiet about the war, and why didn't they stop the war and the genocide from happening.
Nowadays this responsibility is pretty deeply ingrained in German culture. Germany renounced its claims east of the Oder-Neisse Line, and Brandt asked Poland for forgiveness on behalf of Germany, which was a start. Generations of Germans now have been brought up in an increasingly pacifist culture and the military is largely unpopular. Germans tend to avoid ostentatious displays of national pride, which it was such a big deal when they waved flags after their World Cup win. Their national military museum is designed to with a glass façade splitting the old armoury like an arrowhead to symbolize the transparent and democratic break with the authoritarian past, with the exhibits designed to show the human cost of war rather than to glorify the military.
This is unlike any other country to my knowledge. Germany was sufficiently broken and humbled, and its atrocities were sufficiently bad, that German society managed to change and face its past. Contrast with, say, Japan, which has never really owned up to the Empire's crimes.
