After WWII, West Germany really did ideologically refound itself on the idea of

“Yikes, let’s make absolutely sure fascism never comes back, let’s also make absolutely sure the threat of communist revolution that (regrettably justified as necessary/was cynically used as a pretext for, depending on individual politics) fascism never comes back”

Then East Germany merged in with its particular streams of “Yikes, without fascism you end up with communism, so full speed ahead” and “Yikes, without communism you end up with fascism, so full speed ahead”, that’s an interesting tension that hasn’t resolved yet.
