There are a few trains of thought that the 200 Million Man Army in Revelation 9:16 is demonic and not human. I tend to lean in that direction since the logistics to just feed, arm, clothe a 200 million man army seems impossible by human standards.
There are plenty of documentaries out there that our wonderful gov’t opened up doors/portals way back in WWII and this has been going on for awhile.
Evil just keeps ramping up.
I have heard that but suspect it’s a human army plus back under Reagan Administration the Chinese told the US they could afford to lose 200 million and not even notice it in the event of a nuclear exchange.
