Very interesting read.  Perhaps this will put to rest rumours and/or affirmations that the Vatican sat back and did nothing!

So interesting isnt' it? In my research what I could find was that the Vatican officially "did nothing" as in the Pope didn't step in, but there was a large group of individuals, led by Monsingnor O'Flaherty who took matters into their own hands. As horrific as this period in history was, there are some incredible stories of human resilience and bravery. 

Perhaps the Pope didn't officially step in but he certainly turned a blind eye to what Monsignor O'Flaherty and others like him were doing.  In other words, he gave his blessing to what they were doing.  While Pope Pius XII has been "blamed" for "not doing anything", there have been numerous testimonies to what he did do and allowed others to do, without accepting accepting "glory".  Sometimes you do have to appear to be "working with Evil" in order to do a lot of good.
