I have no doubt that that Pope had some skeletons in his closet...but see David Irving's videos on the Holocaust...2-3 million jews were killed at Operation Reinhard camps of Sobabor,Treblinka, Belzec those records exist as intercepts of communicatioms to and from Heinrich Himmler.What does not exist however, is any record or physical evidence of gas chambers for anything other than cleaning clothes (too small for groups of people), especially at Auschwitz. I suspect the meme of Auschitz as a death camp is an intel agency effort to conceal large scale Uranium enrichment efforts that went on at the IG Farben "Buna" plant. See Carter Heydrich's "Critical Mass" for more on that part.
