“Before the war Poland was only marginally less semetic than Nazi Germany of that time”
Utterly unknow is the effect of the waves of penniless, illiterate, often diseased who, fleeing from the ghettos of Russia, {now Poland}, through the porous, illogical Versailles borders into the remnants of a prostate, democratic Germany, bore on the eventual rise of Nazism.
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.
