You now, the war was bloody, Poles were systematically exterminated, I hear thet 50% of Polish teachers were killed. When the underground killed one German soldier, several dozen Poles were killed in retaliation.
It's the Opole region, the center of the German minority. Tensions grow throughout Poland. I see a return of anti-German propaganda which we haven't had since 1989.
Simple thinking: Soon America will be 50% non-white (2042, according to estimates), and then for example it may be disarmed like South Africa. The next step: Russia or Germany invade Poland. This fear is growing, for Poles everything hinges on America's military strength, like for many nations in Central Europe.
The expelled Germans in FRG are active, oppose the Yalta order (Erika Steinbach). Germany is overpopulated (twice the density in Poland). Germans are very active economically inside Poland (newspapers, plants, sale of cars).
