On the Fact that There Haven't Been a Huge Number of Multi-Ethnic Societies that Have Succeeded Once the Disparate Populations Became Obsessed with Their Grievances, Formed Solidarity, and Used Tribal Venom to Advance Their Respective Agendas

And once these societies ultimately do crater, four possibilities; a) the development of cohesion (the best outcome), b) a peaceful separation of the various groups (the second best outcome), c) a violent separation of these groups, and d) the emergence of some dictator who keeps the society together by brute force and intimidation (a la Saddam Hussein, Tito, etc.).......So, any predictions as to our course? Please, make it a or b.
