Your solution for ethnic independent states still doesn't end ethnic conflict though does it? Say if Scotland broke away from the U.K but still kept an ethnic diverse population of Pakistanis, Chinese etc, there is still ethnic conflict and division. Sure it's not armed conflict but there's still discrimination and that's where armed conflict arises from.
Anyway you haven't really answered anyone's questions or countered anyone's evidence proving your idea won't work. All you've done is give answers that contradict the OP or just said "And your solution to such and such?" or "Do you support so and so's struggle for independence?" what's your solution to these problems? other than your rather mental idea of dividing the world even further.
dividing the World??
or sharing the World mor fairly and giving people the chance to run their own lives/affairs.
You hav a house and a garden and so does your neighbour and you (plural) aren't at each throats all day trying to kill each other (mostly
) are you.
