If you can find a copy, Leon Uris’ “Armageddon” is worth readingf. A novel of the American occupation of Germany just after WW II, Uris does a superb job of peeling back the entrenched layers of Nazism in the German soul and psyche. The majority of the references are solidly factual. He really goes after the German people’s adoration of Wagner..
Uris really gave it to the Germans in the 1960s! I loved his books. Of course, Exodus being my very favorite.
