The head Rabbi of Rome became a Catholic after the war.
I know he may have been smeared, and maybe I'm influenced by this. Don't get me wrong, I think Pius XII was a fascinating character, and making the choices he had to face was certainly not easy when you had Communism and Fascism prospering at the same time.
Still, I regret he did not have the same words as his predecessor to condemn more firmly what Hitler did to the Jews AND to Christians, especially to Catholic priests.
