“Hmmm/ are you sugesting that Germans after 1919 could not control their new borders?”
Of course I am..
Firstly the borders were not even decided for several years, and the only real military authority in the east for a while were the private armies, the infamous “friekorps”. The German military had been dispatched by the Allies and then later limited to what? 100,000? Even the formerly prosperous native German jews were frightened by the effect of the waves of new immigrants fleeing the new Poland into a newly poverty sticken Germany with no jobs, food or prospects.
Yes, I'm pretty sure some of this did happen. But even more suspect the extent of it was grossly exaggerated by the Nazis for their own political purposes.
And I've never seen statistics to demonstrate there was an "explosion" of the Jewish population in Germany after 1919.
Remember, we're talking here about less than one half of one percent of the German population, for crying out loud!.
"Waves" indeed.
Can you provide a reference?
