Lord Haw Haw would be a closer approximation. Just before the British strung him up for treason in 1946, he said, "In death as in life, I defy the Jews who caused this last war, and I defy the powers of darkness which they represent."
BTW, speaking of approximations, the treason charge was a bit bogus, since he was actually an American who had become a German citizen and never had been a British subject, although he carried a British passport.
One hopes Gadahn won't be captured alive. To judge from Leonie Brinkema and the twelve dumbest of greater Alexandria, Americans have lost the knack for approximation.
Thanks for the comments.
