The USA as Babylon
The USA is the nation that could just go to another nation and hammer it down. Like they have done with Vietnam, Afghanistan, Iraq etc.
(Jeremiah 50:23 [KJV]) How is the hammer of the whole earth cut asunder and broken! how is Babylon become a desolation among the nations!
So they can be seen as the hammer of the whole earth and therefore also as Babylon, or the daughter of babylon.
Washington DC, which is a city could then be seen as Mystery Babylon.
(Revelation of John 17:9 [KJV]) And here is the mind which hath wisdom. The seven heads are seven mountains, on which the woman sitteth.
The seven mountains would then be the seven continents of the earth.
(Jeremiah 50:8-13 [KJV])  Remove out of the midst of Babylon, and go forth out of the land of the Chaldeans, and be as the he goats before the flocks.  For, lo, I will raise and cause to come up against Babylon an assembly of great nations from the north country: and they shall set themselves in array against her; from thence she shall be taken: their arrows shall be as of a mighty expert man; none shall return in vain.  And Chaldea shall be a spoil: all that spoil her shall be satisfied, saith the LORD.  Because ye were glad, because ye rejoiced, O ye destroyers of mine heritage, because ye are grown fat as the heifer at grass, and bellow as bulls;  Your mother shall be sore confounded; she that bare you shall be ashamed: behold, the hindermost of the nations shall be a wilderness, a dry land, and a desert.  Because of the wrath of the LORD it shall not be inhabited, but it shall be wholly desolate: every one that goeth by Babylon shall be astonished, and hiss at all her plagues.
USA is probably the youngest nation. So it fits with "the hindermost of the nations". So this would also suggest that Babylon is USA. It would also suggest that USA is going to fall and that those that attack it will attack it from the north. It also suggest that USA after that it has fallen will be a dry land, a desert and wilderness and that it shall not be inhabited.
