Neither the Pope, nor the Church, was never in league with Hitler, revisionist history to the contrary. The Catholic Church was the only major religious institution that spoke out against Hitler during WWII. Hitler hated the Pope, and it was the first time in history that the Swiss Guard actually carried firearms, in order to protect Vatican City.
The Pope allowed many networks to run, and funded them when possible, that saved many Jews throughout Europe. The actions of many priests, nuns and laypeople in trying to save Jews resulted in their being sent to concentration camps, where they died, along with the Jews. The Pope is one of the reasons why Italian Jews survived in such great numbers. Italian Nazis weren't hot to trot about rounding them up, after the order was given. It took the Germans coming into the country to do that. But by then, the escape lines had been well established and were run, not only out of the Vatican, but in parishes all over Italy.
And yet those famous Ratlines whisking Nazi war criminals off to South America to escape justice for their war crimes ran right through the Vatican.
