A contingent from the Lakota Nation is attempting to secede from the U.S., citing violation of treaty agreements.
I found this story on Metafilter. Someone in the comments section said, referring to the non-Lakota people living in the disputed region:
"It also includes countless private residences and property. Imagine waking up and learning that your house is now in land claimed as part of someone else's country."
Imagine that, indeed! Waking up one morning, and finding that someone has claimed your land as their own! Without even asking! And now they want you to submit to the rule of a foreign government! Run by people who aren't even the same race or culture that you are!
(I LOLed. The sad, ironic sort of LOL.)
