As much as I enjoyed “Exodus” by Leon Uris, he was one of the first to push this idea that the camps were somehow the Poles fault. He’s quite vicious about it too.
Here in NJ (Jersey City), Poles last year successfully fought to keep a 30 foot+ statue commemorating the Katyn Forest massacre at Exchange Place; the Dem mayor (who happens to be Jewish) wanted to relocate it, and many Poles saw this as part of the re-writing of the history of that period. The President of Poland visited the site, and in the end the Poles prevailed; Polish people have very little patience for this, and understand what is happening all too clearly.
There was a lot of anti-Semitism throughout Poland and Eastern Europe and Russia in general. It certainly was not specific to Poland. Uris' Mila 18 is a great tale of the Warsaw Occupation and uprising.
