I've covered Mystery Babylon somewhat in this thread so won't reprat what I've already posted, but I would like to add this:
The woman on the beast maybe rules the 7th kingdom, which also encompasses all other empires before it. Moreover, she spread her influence throughout the entire world - so we can have this global world order.
This would fulfilled the eighth kingdom being also of the 7th - because it is worldwide.
The question is how does this global world order become the new world order - if Mystery Babylon is destroyed by the beast and the 10 kings?
----
Besides mystery Babylon and antichrist identities being a secret up to this point - we have the 10 kings who we know very little about.
Quoting: Anonymous Coward 71703095 Supporting verses Mystery Babylon:
Rev 17
7 ...mystery of the woman, and of the beast that carrieth her, which hath the seven heads and ten horns.
8 The beast that thou sawest was, and is not; and shall ascend out of the bottomless pit, and go into perdition:
-------
10 And there are
seven kings: five are fallen, and one is, and the other is not yet come; and when he cometh, he must continue a short space.
11 And the
beast that was, and is not, even he is the eighth, and is of the seven, and goeth into perdition.
12 And the
ten horns which thou sawest are ten kings, which have received no kingdom as yet; but receive power as kings one hour with the beast.
16 And the
ten horns which thou sawest upon the beast, these shall hate the whore, and shall make her desolate and naked, and shall eat her flesh, and burn her with fire.
