I see the UN or an Islamic Caliphate (or even a combo of both) as the beast but Rome is the top contender for mystery babylon.
No nation sneezes without Rome's opinion on the matter.
Keep in mind that the beast will hate and destroy the woman (mystery babylon).
New York doesn't really fit scripturally as the woman.
I understand your argument and vehemently defended the same until I learned more about mystery religions.
Mystery religions were based on secret knowledge that was purposefully withheld from the masses by a few informed individuals. Back then, mystery religions were based on astronomy. A few men would conspire to captivate the masses by suggesting that if they did/did not do a certain thing, then the gods would be angry and would cause the sun to turn dark or the moon to turn red. When the threats were confirmed, the masses fell in fear behind these individuals, later called priests.
The kings would see that support and would pay the priests in wealth and authority in exchange for their loyalty to the kings. With the priests backing the kings, calling them gods, the masses would follow the kings without question. This is evidently called out in Revelation 17:1-3 when it reads, "Then one of the seven angels who had the seven bowls came and said to me, "Come, I will show you the judgment of the great prostitute who is seated on many waters, with whom the kings of the earth have committed sexual immorality, and with the wine of whose sexual immorality the dwellers on earth have become drunk." The sexual immorality is mingling of false priests with ordinary politicians to lead the masses into committing abominable acts.
Otherwise, I hardly see a reason to build such great monuments to kings as though they were gods or fight such great battles and conquer territories as if the lives of those they conquered were illegitimate. We have long known that most politicians only do what it is in their own best interest, and that often involves money and power. Same with criminals.
Now, we can follow the mystery Babylon along the heads of the beasts with the mystery religions:
1) Egypt
2) Assyria
3) Babylon
4) Persia
5) Greece
6) Rome (Domitian had the secret cult priests stand on each side)
7) New York City
The reason why I say New York City is because, in between the time of the sixth and seventh head, the mystery religions were destroyed by Constantine, who moved the capital of the Roman Empire to Constantinople (which was built on the ruins of pagan gods to demonstrate Christianity's victory over paganism.)
By the time the Christian empire collapsed in front of Napoleon Bonaparte and his French Empire, astronomy was no secret. People were informed. That means that the next mystery religion could no longer use the stars to deceive people. There was one thing that would soon appear that would give insiders an edge over the rest of the masses: The Stock Market.
Formerly, people would go to war because their religious leaders and supported kings would tell them to go to war. It was their divine duty to serve the interests of their divine rulers without question. Just after WWI, it became evident that divinity was out of the question and that something else began to drive wars and great empires. That was the stock market. Stocks collapsed before WWII, which caused awful conditions in Germany. During WWII, especially during the Pacific campaign, the U.S. told people that it was their patriotic duty to buy stocks. What people learned after that was that war makes investors a lot of money.
The Gulf of Tonkin incident which sparked the Vietnam War has been proven to be a lie. The controversy surrounding the Gulf War incident, regarding what the Iraqis did to the Kuwaitis when they invaded Kuwait, has been shown to be a lie. The 9/11 attacks are the subject of so much controversy because, a day before, 2.3 trillion dollars went missing and unaccounted for. The records of the incident were in the section of the Pentagon that was hit by a 'supposed' airliner. Just preceding the BP oil spill, Haliburton pulled its stocked and bought the company Boots and Coots, which cleaned up the oil spill (supposedly.) We see this crisis capitalism sprouting up more and more frequently.
The more war and political intrigue, the wealthier Wall Street gets. When an earthquake hits Japan, stocks move to safer investments. The companies that make out big are the ones that knew about it before it would happen. This insider trading shows that there is a system that is manipulated to accrue wealth and consumerism. That is why Politicians are so wrapped up in corporations and investments.
Wall Street Insiders are the new mystery religions. People go to war and conquer other territories because companies and bankers want more money.
That brings me to the beast. Since we don't yet have a name for it, lets call it the New World Order. I know its typical, but please bear with me.
Currently, we have the United Nations with the biggest runners being Europe, China, and the United States. Currently, we are seeing a great amount of corruption in each of those systems. With the euro collapsing and the U.S. dollar being submitted to inflation, the Chinese are now aware that they have overextended themselves. What follows next is an inevitable collapse of the economic system. Before that happens, look for criminals trying to sap everything out of the system and moving their investments to safer places.
If 9/11 was a sign to us, then we should see a great oddity with the stock market just before its collapse. To cover up the tracks, New York City will be destroyed. (Assuming that I'm correct about this.)
The New World Order will destroy Wall Street and will present a backed currency along with a new Constitution. People, in their desperation, will cling to it. What follows will be very dark times for many. We can already see the thick clouds on the horizon. Many people are chiming into this and calling out to the masses through social media to take heed of the failing economy. Some, to include Lindsey Williams, are even going as far as to say that an elite group of bankers are holding off the collapse of the stock market until the end of the year.
All of this can be speculation and it could be false. But one thing is true: Once mystery Babylon is destroyed, there will no longer be a false system to manipulate people into following politicians in their wicked schemes.
