Armageddon

The prophecies of the Day of Judgment, or Armageddon, are named for a mountainous region of Israel called Har Megiddes where several major battles were fought, and were intended to be prophecies of the end of Israel, not the entire world.

In fact, the final days of Israel, whose rebellion was finally smashed by the Roman Empire in 73 AD, which ended at Masata and with it biblical Israel, were not even the end of the Roman Empire, nor any surrounding nations. The Roman Empire became the Holy Roman Empire (basically the Catholic Church in Rome), began conquering neighboring lands with its own army, eventually resulting in the medieval era (the Dark Ages), and the plague, which drained the manpower from both the fields and the churches; the church lost most of its support (and attendance) by burning scientists and others disagreeing that the plague was caused by "sin and unrighteousness", rather than a transmitted disease we could cure. This was actually closer to a real extinction, as 75% of Europeans died.

Israel was not a nation again until after World War II, established again in 1948 by the United Nations, and at the suggestion of England, was given the land of the biblical Hebrews.

The Book of Revelations is not about the "Day of Judgment" at all. It was written by John, a political dissident, exiled to the Greek isle of Patmos, who used symbolism understood by scholars of the day to criticize several empires, such as the Babylonian and Assyrian, and historical rulers in the Middle East.

So Armageddon did happen, but for biblical Israel and is now history. People will keep the idea going just to write books and sell tv shows, but its been reduced to an income generator by modern capitalism.
