Speaking from a SPIRITUAL point of view (NOT a human p.o.v., with our limited, geopolitical sense of reality) you have to wonder why someone would oppose Israel being in a position to have all the prophesies in Revelation come about. What would be the AGENDA of someone who does not WANT the events of Revelation to transpire?
I've asked for you to back that statement up. From your silence I am forced to conclude that you are unable to. Therefore your charge that Pius XII was "thwarting the will of God" is erroneous at best, malicious at its worst. The facts demonstrate that Pius was an able and willing friend to the Jews of Europe during the Nazi occupation and many notable Jews acknowleged that fact during their lifetimes( Golda Meir for one). His opposition to a Jewish state was not contrary to some fraudulent interpretation of Revelations, as you suggest, but rather consistent with his history as a friend to the Jews and Christ's teaching of brotherly love.
