> Countries are not people, they don't respect or love each other, they oscillate between peace and war. The history of every major nation is a history of violence and conquest, not freely entered union.
IMO that has not been true for last 70 yrs. Point to me a war that has been People vs People.
The fact of the current world is People Are Sovereign. If some >=N people domiciled in continuous region wants self-determination, thats their human right.
