"Babylon" is cast down!
Note that while the corrupt aspects of 1st century Jerusalem are included in what Revelation's symbolic "Babylon" (Revelation chapters 17-18) represents, it represents much more than just the corrupt aspects of 1st century Jerusalem. For 1st century Jerusalem just by itself didn't reign over the kings of the earth (Revelation 17:18). Nor was 1st century Jerusalem the only place where people bought merchandise (Revelation 18:11). Nor had 1st century Jerusalem just by itself corrupted the entire world (Revelation 18:3). Nor had 1st century Jerusalem been continuously supported by the empires of fallen man throughout history (Revelation 17:9-10). Instead, Revelation's symbolic "Babylon" represents all of mankind's corrupt political (Revelation 17:18), economic (Revelation 18:11), and religious (Revelation 18:24) systems throughout the earth (Revelation 18:3), and throughout history (Revelation 17:9-10).
In Revelation 11:8, the great city is Jerusalem, where Jesus was crucified. But in Revelation 21:10, the great city is New Jerusalem, which is now in heaven. And in Revelation 14:8, Revelation 17:18, and Revelation 18:10-21, the great city is the symbolic harlot/city of Babylon. When it's destroyed, it will be found no more at all (Revelation 18:21), forever (Revelation 19:3), unlike Jerusalem, which was found again after its only-temporary destruction in 70 AD.
The 10 kings of the Antichrist's empire will destroy with fire what Revelation's "Babylon" represents (Revelation 17:16-17) when they destroy the cities of the earth (Revelation 16:19), probably with nukes (and probably with Fission-Fusion-Fission, "FFF", or "666", nukes, "F" representing the number six in English gematria), at the time of the 7th vial (Revelation 16:17,19), which will be the final event (Revelation 16:17) of the future tribulation of Revelation chapters 6 to 18 and Matthew 24, right before Jesus' 2nd coming (Revelation 19:2 to 20:6, Matthew 24:29-31). They could do this under the direction of Lucifer/Satan (Isaiah 14:17,12), who could want to leave only a literal "scorched earth" for Jesus to return to.
Near the very end of the future tribulation, Lucifer (employing the ancient lies of Gnosticism) could say to the Antichrist and his 10 kings something like:
"Our great battle against the evil, tyrant god YHWH is about to begin [Revelation 16:14, Revelation 19:19], a battle which we will win, and so we will be able to escape YHWH's prison house, this material universe, and return to the wholly-spiritual Pleroma [i.e. Heaven]. So let us now destroy this prison cell, this foul planet, and let us, as it were, burn up all the gewgaws which we have hung upon our cell walls. Let us burn up all our great cities, all our magnificent systems. Let us break all our chains of attachment to this vile physical realm, that we might more freely ascend back to our rightful place in the Pleroma [Isaiah 14:13-14]".
Of course this will be a lie. For at his 2nd coming, Jesus (who is YHWH: John 10:30, Zechariah 14:3-4) will completely defeat the world's armies, arrayed against YHWH (Revelation 16:14, Revelation 19:19-21). And Jesus will have Lucifer bound in the bottomless pit during the subsequent 1,000 years (Revelation 20:1-6, Isaiah 14:15). And Jesus will restore ruined parts of the earth and make them like the Garden of Eden (Ezekiel 36:35, Isaiah 51:3). And after the 1,000 years and subsequent events (Revelation 20:7-15), God will create a new heaven (a new 1st heaven, a new sky/atmosphere for the earth) and a new earth (a new surface for the earth) (Revelation 21:1). And then God will descend from the 3rd heaven in the literal city of New Jerusalem to live with saved humanity on the new earth (Revelation 21:2-4).

The harlot rides the beast and is then devoured by the beast.
The 7 heads of Revelation's "beast" in its empire aspect (Revelation 13:1, Revelation 17:3) represent 7 different empires (Revelation 17:9-10): Egypt, Assyria, Babylon, Medo-Persia, Greece, Rome, and (possibly) Islam. The first 5 had fallen by the time of John the apostle in the 1st century: "five are fallen" (Revelation 17:10, Revelation 1:1b-2). The 6th (Rome) existed at the time of John: "one is" (Revelation 17:10). The 7th (possibly Islam) hadn't come by the time of John: "the other is not yet come" (Revelation 17:10). The empire of the Antichrist (the individual-man aspect of the beast) will be a different, still-future, 8th head (Revelation 17:11), which will be a revival of one of the 5 empires that had fallen by the time of John (Revelation 17:8,10,11). It will be a revival of the empire of Babylon. The Antichrist will transform the present-day, rebuilt city of Babylon (in Iraq) into the capital of his world empire, only to see his city of Babylon ultimately destroyed at Jesus' 2nd coming (Isaiah 13).
Before the 2nd coming, when the world is brought into the worship of Lucifer (the dragon, Satan) and the Antichrist, during the Antichrist's future, literal 3.5-year worldwide reign (Revelation 13:4-18, Revelation 12:9), the Antichrist will build their main temple in the city of Babylon. For a temple to "wickedness" will be built in Shinar (Babylonia) (Zechariah 5:8,11), and the Antichrist is called "that Wicked" (2 Thessalonians 2:8). Also, the dragon has been the god worshipped in the city of Babylon since ancient times.
The Antichrist may claim to be Nebuchadnezzar returned, and so reinstitute the system that Nebuchadnezzar set up whereby everyone had to worship an image or be killed (Daniel 3, Revelation 13:15). The Antichrist may also claim to be, at the same time, the return of Nimrod (the founder of Babylon: Genesis 10:8-10), and Hammurabi, and Asoka, and other famous rulers of the past. For he may claim that he has had many different "past lives" as various "enlightened" rulers.
Besides building a main temple in Babylon, the Antichrist will also sit (at least one time) in a future, 3rd Jewish temple in Jerusalem, and declare himself God there (2 Thessalonians 2:4, Daniel 11:36,31, Matthew 24:15, Revelation 11:1-2). The Antichrist could also sit (at least one time) in other religions' holiest shrines, and declare himself to be God there as well. For example, he could also sit in Islam's Kaaba in Mecca, in the Sikhs' Golden Temple in Amritsar, in Catholicism's St. Peter's Basilica in the Vatican, etc.
