No. It’s pretty well documented. Pius himself said he held back so as to save Jews. Let me see if I can find the quote again, because I checked before I posted. I don’t say things like that without cause.
Pius MAY have adopted a “stand off” policy to save as many as possible, but I would not call this a failure.

This is a very very short list and does not include anything Pacelli did before he became Pope Pius XII.
It has been noted that when Pius made public statements the Nazis stepped up executions of Jews and Priests.
No, he never said anything. Same old crap.
