You may be right. I only have a few ideas of how this plays out. It's very complicated and much is still 'sealed.' I believe whomever this modern Babylon is (I think it's likely America), is about to get hit by a massive attack. Those countries left, China, probably Russia, Iran, etc, will duke it out with Israel, eventually. When all seems lost, I think that's when Christ will come to the aid of Israel, but only after He's asked to.
I also believe the 'rapture' for those 'in Christ' will occur at some point. Hopefully before the worst parts of this take place. JMHO ...
Lots, and lots, point to this being the end of age the bible talks about.
