As the title says, I believe there are too many countries in the world.
The UN recognises 193+2 nations. That’s way too many to have any kind of dialogue. Plus a lot of these small countries are way too weak and poor cause of their size.
Dumb imperialistic mofos broke up countries along random lines, and now we have a smattering of nations.
Edit: a lot of them should have coalesced like the US.
