In 50 years, I predict that “Nationa States” will be in decline. Panfederated regional or continental states will be what replaces them.
All you have to notice is that history has always demonstrated that states grow. From city states to China.
The EU is the U.S. They either get rid of the EMU due to the fact that none of the nation states follow the rules of ratification (think AoC) and become independent nation states, or they sign the Constitution and create a pan-federal-European government with the power to enforce laws in all nation states. The African Union has taken steps, and the SCO & BRICS as well, to get out from under nation state dependancy by globalizing.
I highly doubt there will be any (or more) geographical space that is a non-statist entity. The only ones that exist are called “protected” because they are a living antiquity used for ethnographic and anthropolgical study. Or they are subjected such as the case with the North American Indian.
It is a race between power and time; the statists seek to wrest all power before time destroys their nation state. The thing is, the statists in the big nation states have seen thefuture of regional and eventually world government that they are trying to increase their influence before it becomes legally codified internationally. The nation state with the most influence at the end of the race will eternalize their influence over the world. With technology what it is today, and its increasing advancement, it is absurd to think that statism will not dominate the future. The best we can hope for really is that collective conscious theory, short of that…a benevolent bureaucracy…
