Thanks for this information. I studied that area years ago. Megiddo has been the area of many battles throughout time, because it was on a major trade route and was a "mighty" city long ago.
Rome was also a mighty city/country in history and "owned" much of the world through conquest back then. All mighty countries in times gone by, that ruled parts of the world, failed. In the future, the United States may fail and be in history as a failed country as the others are. My opinion is, China will be the major country at that time. Or, Christ will return before that happens.
