Agree with that which you posit, already underway and will be come a stampede once it happens
It has been my thought that Europe would never hold together.
This goes back to another age and the Babylonian idol.
The feet/toes were made of iron and clay, which would never hold together.
Some folks have thought of the feet as Europe.
Babylon, Persia, Alexander the Great, the Roman Empire, and the break up of power to the nations of Europe.
Not sure anyone is into this much, but it does seem to fit what took place.
It’s spoken of in Daniel 2.
