This is a FLAT OUT LIE.
The tree in the picture is planted at Yad Vashem for the Ten Boom family - who were Protestants

and it's not the only one
There is also a huge monument at Yad Vashem dedicated to Village of Nieuwlande - every Protestant family in that village hid at least one Jewish person from the Nazis

Thank you for that information. Unfortunately, it does not jibe with what the Catholic League would like us to believe, therefore the information will be branded as being anti-Catholic.
For the record, Corrie Ten Book was awarded the honorific "Righteous Among the Nations" by the State of Israel on December 12, 1967, for her actions on behalf of the Jews during WWII. While many Catholic priests and officials have also been awarded with this honor, Pope Pius XII has not received it to date.
