"My judgment cannot but be positive. Pope Pacelli was the only one who intervened to impede the deportation of Jews on 16 October 1943, and he did very much to hide and save thousands of us. It was no small matter that he ordered the opening of cloistered convents. Without him, many of our own would not be alive."
