Interetsing.
As a Biblical student of decades of learning, and still learning, I will tell you a MAJOR flaw in the article.
the KING of the SOUTH.
In scripture where these Kings are described, the direction is relevant to Jerusalem. The nation Israel and in particular Jersualem.
So, what nation that wants to destroy Israel is SOUTH of her?
The King of the NORTH is RUSSIA, and encompasses various other countries.
Gog and Magog will rise up against HIM?
WHO is HIM? The Antichrist, ruling in Jerusalem at that end time.
The Saracens seem to be who is referred to as the King of the South and that would include the Turks and others who ride swift horses and have multitudinous peoples.
The United States is not mentioned at all. The author is obviously Biblical ignorant....
sorry...
