On the Fact that India Was One of the Most "Diverse" Countries On the Planet and it Worked Out so Swimmingly Boffo There that Two Large Chunks of it Broke Off and Formed Pakistan and Bangladesh

And unfortunately that's what I see happening in America; the Southwest breaking off and forming an Hispanic country, the Midwest breaking off and forming a white European country, the Southeast breaking off and forming a black country, and the Northeast continuing with this multicultural experiment. I could be wrong (and I clearly don't have a precise timetable) but I doubt it.
