You're going to be seeing more of this in the future, unless the NAU gets forced on us really hard. Moreso if the "welfare state" system starts to break down. Perhaps in the future you'll see the Southwest US being officially reclaimed by Mexico, or even a new nation called "Aztlan", or something akin to it. The Asians might want a slice of the Pacific northwest. Perhaps African Americans might want a large portion of the Southeast to themselves. The other Native American tribes might just follow along. Hell, the Seminole Indian Tribe down here in So. Fla. never signed the peace agreements with the US, so technically, they are still at war with us.
Various cultural, ethnic, and religious groups all taking little slices for themselves. The tenant of multiculturalism and diversity is destructive onto itself and has caused tens of millions of lives throughout history. It goes against human nature, and that is something you can't legislate.
I do wonder, however, that the doctrine the UN put out that specifically protects indigenous peoples extends to native Europeans as well.
