Ah, the Internet, source of all truth. Do you care to show a source?
I have some sources of my own.

Pinchas Lapide, a Jewish theologian and Israeli diplomat to Milan in the 1960s, wrote in Three Popes and the Jews that
Catholics were “instrumental in saving at least 700,000 but probably as many as 860,000 Jews from certain death at Nazi hands”.[129]
According to Rabbi David Dalin, in the aftermath of the war,
Jewish leaders who hailed Pius XII a righteous gentile for his work in saving
thousands of Jews included the scientist Albert Einstein, the Israeli Prime Ministers Golda Meir and Moshe Sharett, and the Chief Rabbi Yitzhak HaLevi Herzog.[132]
The Chief Rabbi of Rome, Israel Zolli, took refuge in the Vatican following the Nazi occupation of Rome in 1943.
After the war he converted to Catholicism and took the name “Eugenio” in honour of Pope Pius XII.
On 21 September 1945, the general secretary of the World Jewish Council, Dr. Leon Kubowitzky, presented an amount of money to the pope, “in recognition of the work of the Holy See in rescuing Jews from Fascist and Nazi persecutions”.[133] After the war, in the autumn of 1945, Harry Greenstein from Baltimore, a close friend of Chief Rabbi Herzog of Jerusalem, told Pius how grateful Jews were for all he had done for them. The pope replied, “My only regret is not to have been able to save a greater number of Jews.”[134]
Catholic scholar Kevin Madigan interprets such praise from prominent Jewish leaders, including Golda Meir, as less than sincere; an attempt to secure Vatican recognition of the State of Israel.[135]
