A family friend who grew up in South America was telling us how it was well known that many Germans who came over after the war were ex-Nazis, and that many kept a bitter conspiratorial hatred toward Allied Countries and "the Jews" for defeating Germany. Wondering if this is something that is chronicled in history.
Not to discourage further answers, but in the meantime you might find this answer I wrote about surveys on pro-Nazi opinions in occupied Germany to be of interest.
