I know the Germans at least disliked the KKK, as this was a [propaganda poster used in the Netherlands.] (https://upload.wikimedia.org/wikipedia/en/f/f8/Liberators-Kultur-Terror-Anti-Americanism-1944-Nazi-Propaganda-Poster.jpg) But I wonder how the KKK felt about the NSDAP.
I've actually written about the Nazis and the KKK, which you can find here. Hope that helps.
