The role of the Pope during World War II is one that has generated a good bit of controversy and this book does a good job examination just what went on. After reading the book I tend to think that if the Pope had tried to do some thing major and open he would have been killed and the Vatican would have fallen to the Nazis for their own perverted use.
The book goes into the predecessor of Pope Pius XII, the Italian government position in relation to the Nazis, various writings of Pope Pius XI that were covered up and or destroyed and concerns that speaking out about what the Nazis were doing might have brought even more trouble to the Jews and the Catholics.
It goes into detail about Pope Pius XII's background. It also covers The Protocols of Learned Elders of Zion, the murder of prominent Catholics during the Night of the Long Knives, the murder of 350,000 Serbs during racial cleansing, what happened to the Jews, Nazis in Rome, Nazis murdering Jews in the concentration camps and murdering Italians and the liberation of Italy by the allies.
That covers just some of the topics in this book. It's very good, very complete and very thought-provoking.
