Vatican Opens Archives Of World War II-Era Pope Pius XII (commentary by David Kertzer)
David Kertzer in NPR, "We know [Pius XII] didn't take any public action...He didn't protest to Hitler. But who within the Vatican might have been urging him to do so? Who might have been advising him caution? That's the kind of thing I think we'll find out, or hope to find out about."
