"Southwest USA = Kosovo < 100 yrs"
Unless the population of Mohammadens in the SW (or elsewhere in the States) gets much much larger, I doubt we'll see another Kosovo here. One of the big things the Hispanics have going for them is that a) they are culturally Westerners (if not Anglo Saxons) and more importantly, b) they are Christians. In the Balkans, the Mohammadens are culturally Turks, a breed of cat not even remotely Western, and they are, well, Mohammadens.
I guess you're right on that. I just saw in Kosovo a group of people moving into an area in such high numbers that they overwhelm the original inhabitants in such a way that the area is lost to them by default.
