I believe that Pope Pius 12 should have come out a lot more strongly against Nazism and Facism before and during WW2. I think that if the Pope had criticized such entities, it would have helped to bring a lot of support to the side of those who were fighting them.
Pope Pius XII was in a difficult position--the Catholic Church needed to have stronger positions against Nazism and Fascism. However, Rome and the Vatican are located in Italy which was under control of Benito Mussolini at the time. Since the Vatican had no standing army that could defend itself from Mussolini's forces, Pope Pius XII was largely silent during World War II. He should have said more but couldn't.
Yes, Pope Pius XII should have come out more strongly against Nazism and Fascism before and during World War II, because he could have helped open the people's eyes and seen that what they were doing was terrible. God would have protected him. It is the job of a church leader to call people out for inappropriate behavior.
Its the basic building blocks of what the religion stands for, I doubt anyone would have raised an eye to him,but maybe he was protecting the Vatican. The world was in chaos then,but he should have stated the church's view on what they did to people, it was an awful era.
Pope Pius XII should have come out more strongly against Nazism and Fascism before and during World War II. Maybe if he had done so then we would have not seen the fall of the country that we did. From my understanding, he did not act the way that he should.
