Indeed. Very interesting. I am sometimes amazed that my high school history teachers were able to make history boring.
"... press coverage of the Bund tapered off as the group declined and public fear of domestic Nazism waned. Hundreds of dispirited Bund members returned to Germany."
"When Hitler declared war against the United States four days after Japan attacked Pearl Harbor on December 7, 1941, Bund members found themselves stranded in enemy territory. Federal agents seized Bund records. Many of its members faced denaturalization proceedings and imprisonment. "
"German Americans continued to emphasize their American-ism after the Pearl Harbor raid. “We appeal to the public not to think that everything German must be Nazi,” declared the Wisconsin Federation of German-American Societies."
"The emphasis on Americanism paid off, and a revival of anti-German hysteria did not occur."
"Most Americans seemed to make a distinction between what they believed were good Germans and bad Germans, and America became a refuge for many German intellectuals fleeing Nazi rule."
"For all its prominence and bluster, the Bund involved only a small portion of the German-American community. "
I am glad to see that America was able to realize that the enemy was those with the Nazi ideology and not simply German ancestry. Interesting stuff.
As for John's comment, "As for the rest, as far as I know, Americans of all ideologies overwhelmingly sided with America during World War II." it does not seem like Nazis in America "overwhelmingly sided with America during World War II". Many went to Germany (willingly or otherwise) or were locked up. The title of this very good article at the URL and quoted from above is, "Americans for Hitler".
Update: Here is the same article as a PDF with a few pictures. http://www.6thcorpscombatengineers.com/ ... Hitler.pdf
