John Emerson may well have a Doctorate in Germanistik. His dissertation may have been on Thomas Mann's Zauberberg and written auf fliessendem, fehlerfreiem, beredtem Hochdeutsch. He spoke really bad German with a hypergrotesque American accent simply for the sake of lulling the Germans into thinking that we Americans are so bad at languages that we cannot be expected to understand any of the foreign conversations we electronically surveil.
If this is the case, it has not fooled the Germans. This is a Straussian trick, to conceal one's nefarious wiles behind a façade of bumbling cluelessness, and Leo Strauß was a German. And John Emerson remains an idiot.
