From the Bible we know that:
1/ The son of perdition or antichrist is real, (Jn.17:12, 2 Thes.2:3, etc.)
2/ That there will be a change of system at a global level, (Rev.13:15-18), and . . .
3/ We also know that mystery ‘Babylon the great‘ will fall, Rev.17 & 18. But it also mentions that the ‘daughter of Babylon’ will fall (Is.47, Jer.-50, 51etc.) because Babylon & daughter are used in an interspersed way, I think it’s considered the same thing, it’s a system (Empire), not necessarily just a single place.
