You ought to take a look at the maps.

Thanks for the pictorial confirmation of my point.

[Ditto]

That was no confirmation of your point. Your point was wrong!

Most of pre-war Poland was not land ruled by Imperial Germany. Only a narrow corridor to the Baltic was under the Kaiser's rule before WWI. Ninety five percent of inter-war Poland was was Polish speaking land ruled by Imperial Russia before WWI, and the Poles earned that land by defeating Lenin's Red Army in 1919. Most of what Hitler seized in 1939 had never been part of Germany.
