If you let the word of God explain what Babylon the Great is, what do you find?
Revelation 17:18 And the woman whom you saw means the great city that has a kingdom over the kings of the earth.
Please, look carefully at what the scriptures say, after that you can start to search for a great city that fulfills this criteria and the rest of the characteristics mentioned in Revelation 17 and 18.
This city is the greatest political power, because it has "a kingdom over the kings of the earth". Democracy and elections don't matter. Have you ever wondered why politicians promise what people want but are unable to deliver once elected? It's because the great city, Babylon the Great has its own goals and agenda.
Revelation 18 repeats the fact that it is a great influential city. World wide trade and commerce is very much dependent on that city. That involves stock and commodity trade and trade of goods of every sort.
This does in no way apply to thousands of different religions.
And if we think seriously, what is driving wars? Are they not primarily because of greed? Are they not primarily about money? Why did the USA not want Europe to buy Russian gas or oil? What is the war in Ukraine really about? Religion? No, both Ukraine and Russia are Orthodox Christian and both were before the war organized under the Russian Orthodox Church. And the war between capitalism and communism? It had nothing to do with religion. Actually most of the wars are not religious.
Revelation 18:18 and cried out as they looked at the smoke from her burning and said: ‘What city is like the great city?’ 19 They threw dust on their heads and cried out, weeping and mourning, and said: ‘Too bad, too bad, the great city, in which all those who had ships at sea became rich from her wealth, because in one hour she has been devastated!’
Religions are not making ship owners rich. But instead it should be one of the great commercial cities in the world.
