Cincinnati, eh?
Hmmmm... are you suggesting that Germans after 1919 could not control their new borders? I think we can easily find numbers for what the Jewish populations of Eastern European countries were before the war.
Those numbers show a few hundred thousand Jews amongst a German population of circa 70 million. Poland, by contrast, had 3 million Jews in a population of 35 million.
So there's no way to reasonably argue that the higher the number of Jews, the more the Nazis.
But this much at least is absolutely true: after the First World War, millions of ethnic Germans were left scattered around Eastern Europe as far away as the Volga in Russia, and they felt threatened and vulnerable.
They wanted strong leadership in Germany to protect and support them.
And they liked what they learned of that young spell-binder, Adolf Hitler.
“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.
