I'm curious if, as an alternative, you'd rather see decentralization (smaller population units), some kind of global superstate, or something else entirely?
We've all seen the poisons of nationalism, but I wonder if what one might call "tribalist" tendencies are so easy to vanquish - assuming one even wants to.
Death to all nations. May no nations exist in the future.
(If you get to spew your ideological bullshit I get to spew my own deeply held and utterly impractical ideological bullshit believes. No, seriously, I want nations to not exist eventually. I think the world would be vastly better without them.)
