Many would place the first world war in the early nineteenth century A.D., a major reshuffling of the power structures of the world. What is described here is perhaps the first world shift in the fifth B.C.. What had begun in a smaller scale in the 6th included Israel but, not Judah nor Eygypt etc... No nation now was allowed by the Lord not to drink from this cup. It was not a war of powerful alliances but of fracturing splits and singular domination. We see here God's greater vision, we have been focused too narrowly on Israel/Judah (false prophets, kings,etc..) and not on the entirety of mankind. The cup is prepared and filled in Jerusalem, but, is shared on all the nations. Babylon is used to begin the drunken slug-fest but, it too fractures soon after and is forced to drink as well by the much inferior Medes. The void is later filled by the Persians and then the Greeks.
