The only requirements for the origin of the AC is that he's from the Roman Empire. If you recall, all subjects of the Western and Eastern Roman Empire are possible candidates. I don't think we will ever know where Hussein's really from. Kenya or the USA would qualify as descendants of the Roman Empire.
I disagree there. The AC is also the little horn out of Greece typlified in Antiochus Epimanes (Dan. 8). He is also called in various places the Assyrian and the King of Babylon, and I suspect that Gog is another title for the same individual.
He's also described as a "little horn" that uproots three larger horns (Dan. 7). Since the horns represent kings, or nations, this implies that he comes from a small nation--one still out of the Roman Empire, so Kenya wouldn't count--rather than a large one, like the USA.
He comes out of Rome, yes, but Scripture seems to suggest that he'll come out of the eastern leg rather than the West. I'm not saying that you're wrong yet, but I do think there is some other Scriptural data that you haven't incorporated into your theory yet.
Shalom.
