For years, many prophecy experts have stated that the '200 million man army' cited in Revelation was probably the Chinese. But there is another large group that specializes in beheadings...
If, and that is a big "if," this is the end times, and Revelation is about to occur, the description of the "horses" with the 200,000,000 in Rev. 9 sounds like a tank force, which would require a major national army, and as of right now, the only possible such army could come from China. OTOH, if the end times wait a few decades or longer, anything is possible.
