It is the lying claim "it did exist" when it did not. The original document to prove the malicious intent of Generalplan Ost has never been found. There is no proof that this plan was a long held ambition of Hitler’s, and kikes frequently try to use this non-existent fairy tale to prove their jewish holocaust fairy tale. Why did it start? The Psychological Warfare division as the precursor to the sham Nuremberg trials. See >>>/polfornormies/
Hitler said England was controlling 400 million in India with just 250,000 English soldiers so it should likewise be possible for Germans to do the same. Hitler outlined how it should be done, by building German cities and villages but explicitly stated that, for the rest of Russia: "in der wir die Russen leben lassen wie sie wollen, nur daß wir sie beherrschen" (we will allow the Russians to live as they chose, we will just govern them). While the term Untermenschen was used, it was never officially sanctioned. Alfred Rosenberg confirmed this. Simply put, jews treat fiction and assumptions as facts. Then if you catch them out on a lie, they'll double down obstinately, repeat the lie with no solid defense yet more empty words, and counter with insults.
