Another stellar episode, Jeff. Can I point out that in 1940-41 British intelligence operations in the US were co-ordinated with the FBI (despite Hoover's opposition) and led to numerous Nazi spies being uncovered. Also, the British propaganda effort was, in-part, a response to a hugely successful pro-German campaign which even used the free postage provided to members of Congress to mail millions of pieces of Nazi propaganda to the public from the offices of fellow-traveller Congressmen and Senators. German agent George Sylvester Viereck was later convicted and imprisoned in 1943 for the astonishing coup of getting the US government to pay for his postage. Of course, none of the politicians were put on trial.
