The Kraut is a self-hating idiot.
What does that mean? Revisionism has crept into both. After all, look who has been running government, education and military recently. I’ve never heard D-Day referred to as an “invasion” until recently; it was always the “landing”.
Orwell’s “Who controls the past controls the future” was paraphrased from the Communist Manifesto, remember.
