I trust Scripture and Catholic saints prophecy more than Nostradamus, who derived some of his thoughts from astrology. He may have stumbled on bits of things to come, or even ripped off some writings of the saints, but his interpretators today can only show a string of "maybe this...or maybe that" and nothing definite.
Meanwhile, Daniel is very clear - Persia is identified as the Ram that goes stomping about causing much harm to Christians "to the north, the south and the meridian".
The Order of St. Benedict has said this Pope will come from their order. It is interesting that Jesus gave his apocalyptic prophecy about the end of time from the Mount of Olives. This Pope will reign during the beginning of the tribulation Jesus spoke of. The 111th prophesy is "Gloria Olivae" (The Glory of the Olive).
The Order of Saint Benedict has claimed that this pope will come from their ranks. Saint Benedict himself prophesied that before the end of the world his Order, known also as the Olivetans, will triumphantly lead the Catholic Church in its fight against evil.
