Ignoring the massive cost, legal hurdles, and the opinion of the residents/government/outside powers, if you could magically grant independence to certain territories or form new bigger nations from existing ones with no repercussions to yourself, what new countries would you create?
Please treat this as a non-serious post, let’s not get into a massive political debate, those never end well.
I’d break them all up into a grid of like…100 miles, squared. Those are the new country boundaries, the rest is up to the people within the boundaries to decide. There are now a shitload of countries. Good luck, everybody.
