The rest of the world will take one side or the other, like it always does, so it's not lot the entire world will be taking on just one nation. History has shown us that if it come to that point, it'll be many nations against many other nations. The Bible prophesizes this.
Then on top of that, the United Nations and WEF are currently pushing for and implementing what looks to be the Mark of the Beast infrastructure in all nations, which is a cashless society with digital surveillance IDs tied to a digital surveillance currencies (blockchain currencies).
And if that isn't enough, people are voluntarily carrying surveillance devices. Carrying a cell phone is like putting an ankle bracelet on yourself so you can be tracked like a criminal.
