“When you hear that the Russians have invaded Crimea, you will know that the bells of geulah have begun to ring. When you hear that the Russians have reached Constantinople, you can already don Shabbos clothes and await Moshiach’s appearance. When Russia captures the city of Crimea than you will start to hear the footsteps of the Messiah are near.”
Many Catholic and Greek Orthodox prophecies also mention the rise of Russia and their conquest of Constantinople (Istanbul) from the Turks. One prophecy states that it is after Russia attacks Turkey that the terrible revolution and civil war will break out in England.
