@LizKat: I don't know whether you have ever read "Albert Speer: His Battle With The Truth" by Gitta Sereny - it covers some of this ground extremelyintelligently - but I recommend it highly.
(I moved this citation of your post over from the movie thread instead of responding there)
I'll try to make time for the Sereny take on Speer.... but next on my plate as far as Germany is concerned is Fritz Stern’s
Five Germanys I Have Known. I was intrigued by bumping into a capsule review of it in
Foreign Affairs and especially taken by the concluding line:
Stern covers an immense stretch of cultural and intellectual ground and is unapologetically fierce in his judgments -- to the education, fascination, and occasional irritation of the reader.
Well so I’m always willing to be at least slightly irritated by any book... This one’s 500 pages of opportunity, divided into accounts of five Germanys including a narrative on the Germany of the Kaiser, some attention to which would seem required for context as to what came after World War I. The other Germanys have been of Sterns’ personal knowledge: the Weimar Republic of his own infancy, The Third Reich, the East/West division during the Cold War, and the unified Germany after 1990. Having fled Germany (although Silesia, so now Poland) for the US with his Jewish family as a child, Stern elected to write the book in English although it has been translated into German as well. Stern eventually became a professor of European history at Columbia.
