It appears that the current pope is about to beatify/canonize Pius XII. Pius XII, pope during World War II, was conveniently located in Rome where he could see first hand the workings of an anti-Semitic fascist regime of Il Duce.
Despite his close proximity, he remained strangely silent and, therefore, seemingly complicit in the doings of the Axis.
It's good to know, if you're a pope, that what you do (or don't do) probably won't affect your prospects for canonization.
