“Im convinced the world would have been much better off had Britain, and subsequently the US, stayed out of WWI, even if it resulted in a German victory.”
My grandfather (who was basically a kid in WWI) turned around and served in the US Army Air Corp.
He always said he served on the correct side of both world wars.
The irony is that at the time of WWI, Poland was still divided between Germany, Austria-Hungary, and Russia.
If you asked most of the Jews at the time, which part of Poland they would have preferred living in, most would have said the German part.
