The dissolution of politically created nations, such as Yugoslavia and Iraq, into ethnic and sectarian offshoots will continue to dominate world politics for a while. Add in the massive uncontrolled migration of middle easterners into Europe and things promise to be interesting. There are a lot more Sudans, and Rwandas to go.
While people like Obama see ethnic, racial, and sectarian divides as part of nationalism, I believe nationalism can exist either with or without those things, and without the two being related.
Though I am by no means a wise man nor one with expert knowledge, my education has at least resulted in the ability, often, to recognize one.
An excellent post, sir.
