Armageddon: An event, yet future, in which a despot from what is modern day Turkey attacks Israel -- specifically Jerusalem before being halted by the power of God residing in his two witnesses (prophets) (see Revelation 11). According to Ezekiel, the military forces would be ultimately destroyed by God, except a sixth part. The Jews are repeatedly described as being "gathered out of the nations." This prophecy, found in Ezekiel 37-38, could only be fulfilled in our day as the Jews were only scattered to the heathen nations once, and that was by the Romans. Ezekiel also repeatedly refers to the wickedness of the Jews as being the reason they were scattered. Zechariah 12-14 tells us the same story, emphasizing the Lord's power in delivering Israel (though many Jews will die in the conflict). Both prophesy that the conflict will be so spectacular that the Jews will never pollute God's name again. In hindsight we can see what today's Jews cannot -- that they were scattered because they crucified their Messiah. And they are gathered to reestablish their relationship and to see for themselves the iniquity of their fathers. In prophecy, Armageddon is the great battle in which the Jews (and Muslims) learn the identity of the Messiah and learn at long last to live in peace.
The above is how most Christians see things. Some believe the land of Gog and Magog to be in Russia, not Turkey, but I believe it will be Turkey. The JW version of Armageddon is self-centered and strained.
