The Nazi's interned him after all, and if one accepts he was conned into making the broadcasts he did for the Germans (as seems likely), then he'd have little love to lose for Herr Hitler. And one note that he added the incredibly Oswald Moseley-esque Roderick Spode and his Black Shorts to the cast in 1938.
