Welcome to the Fourth Kingdom - You're In It Right Now
https://www.kingjamesbibleonline.org/2-Esdras-Chapter-11/
>And the fourth came, and overcame all the beasts that were past, and had power over the world with great fearfulness, and over the whole compass of the earth with much wicked oppression; and so long time dwelt he upon the earth with deceit.
>For the earth hast thou not judged with truth.
>For thou hast afflicted the meek, thou hast hurt the peaceable, thou hast loved liars, and destroyed the dwellings of them that brought forth fruit, and hast cast down the walls of such as did thee no harm.
Unlike past empires which grew from armies and simply fought over who gets to rule each other, this empire was built on usury and central banking and declared war on God Himself. Then it corrupted the whole creation towards evil and now it and everyone in it has to be wiped out just like the days of Noah.
