Well put. I work with a number of Poles who are infuriated by these accusations; the reason so many Jews lived in Poland was because they were treated so well. Unlike some other European countries, Poland actually fought for its independence against both Nazism and Communism. Unfortunately they were damned by geography and the lack of will of the West to counter either of those forces.
Ref the “lack of will of the west” is all too true. FDR was the biggest collaborator with Stalin in undercutting Churchill in dealing with Stalin on Poland. The book “A Question of Honor: the Kosciuszko Squadron” by Stanley Cloud and Lynn Olsen gives pretty good details of how things were played by FDR.
