I wish 2 of the biggest brains on this site hadn't already done such a good job at answering. What people do not realize is that we are all tribal somewhere in our past heritage. Though 2 tribes may occupy a single country or land does not mean that they are the same, in dress, speech, Religion ETc... Which is why so much unrest in middle East. Some English Governor or something drew lines on a map and included enemy tribes in the same zone, without understanding the ages old conflicts of these various 'tribes'. He gave these countries acronyms for the various peoples who inhabited the area.
