An interesting document, with further correspondence supposedly indicating Hitler read and approved of it. Here is a key section:
Within a very few years--I should think about 4 to 5 years the name of the Cashubes, for instance, must be unknown, because at that time there won't be a Cashubian people any more (this also goes especially for the West Prussians). I hope that the concepts of Jews will be completely extinguished through the possibility of a large emigration of all Jews to Africa or some other colony. Within a somewhat longer period, it should also be possible to make the ethnic concepts of Ukrainians, Gorals and Lemcos disappear in our area. What has been said for those fragments of peoples is also meant on a correspondingly larger scale for the Poles.
A basic issue in the solution of all these problems is the question of schooling and thus the question of sifting and selecting the young. For the non-German population of the East there must be no higher school than the four-grade elementary school. The sole goal of this school is to be--
Simply arithmetic up to 500 at the most; writing of one's name; the doctrine that it is a divine law to obey the Germans and to be honest, industrious, and good. I don't think that reading is necessary.
What do you guys think of this? #1 there is the notion that larger nationalities will be "extinguished" (this was standard Bolshevik practice). But more than this "alien races" would on the whole be not given the opportunity to receive public education beyond the most rudimentary level. This seems like an extreme practice. Even subjugated Colonial people were allowed schooling beyond this level.
Further comments that these "alien races" were untermensch (translated as subhuman) supports the idea of General Plan Ost - ie widespread subjugation and takeover of vast areas in the east - which is not at all supported by the historical record.
I believe General Plan Ost to be an accusation designed to prop up the Holocaust myth. If the Germans were treating the Slavs this bad, what about the Jews, a race they had much more animosity towards? For these reasons this document is very suspicious to me.
