Hi Sid,
First I want to say that it was normal and fair that the poles had their own independent state after the world war I.
Agree for the Poznan area (Prussian then german since 1772, in 1910 1 973 000 unhabitants with only 679 000 germans so 1/3 german 2/3 pole)
but the way that the allies used the scissors to cut the map of the High-Silesia ( austrian then since 1742 prussian) to german and pole cantons was very "strange"( 893 000 unhabitants in 1910 1/3 poles 2/3 germans). What about the case of Dantzig ( do you know that the concept of free city was an idea of Napoleon). For Dantzig and its corridor : 470 000 poles, 106 000 cachoubes and 885 000 germans. And what the allies did : the city won't be german.
How many germans had to leave their "heimat", for Warsaw only 30 000 but the number of 500 000 was more realistic. Not only by the force but also by will to stay in a german country, I mean in the cultural way.
You've talked about the Alsace Lorraine, you were right but the case of the Saar was "special". Surely the frenchs dreamt of Louis XIV but fortunaly they didn't use the Turenne's method.
I would talk too about 1923 in Germany. For a pretext of 100 000 pylons, the belgians and the frenchs invaded the Ruhr. Without that Hitler would have been totally politicaly dead. That was a big mistake.
But I'am agree with you for the theory of the "stab in the back made by the jews". All extremists use the scapegoat theory. It's a bullshit but it's more popular and easier for reaching the power.
Sid, don't forget that english was not my birth language so I have a lot of difficulties to translate what I want to mean. but, it's great to talk with you. I do appreciate it and I take care about your posts. I'am learning as I go. I don't forget your P.S.

So long Sid.
