I’ve heard of utopian scenarios where there’s lots of large communities that each live in line with their values. Perhaps it’s a similar line or thinking.
Anyway, to an uneducated mind this sounded interesting (not that any powerful nation would allow it).
Theoretically, if it were possible what would be the pros and cons? I’m guessing something like WW3 becomes less likely?
I think your guess is backwards: attempting to split up countries makes war more likely if you look at the record, at least, a local war.
Hint: not great for the small entities. Usually great for the big ones. Not exactly shocking
