The Lakota Nation has Suceeded from the USA.

Descendants of Sitting Bull, Crazy Horse break away from US
The Lakota Indians, who gave the world legendary warriors Sitting Bull and Crazy Horse, have withdrawn from treaties with the United States, leaders said Wednesday.
"We are no longer citizens of the United States of America and all those who live in the five-state area that encompasses our country are free to join us," long-time Indian rights activist Russell Means told a handful of reporters and a delegation from the Bolivian embassy, gathered in a church in a run-down neighborhood of Washington for a news conference.
A delegation of Lakota leaders delivered a message to the State Department on Monday, announcing they were unilaterally withdrawing from treaties they signed with the federal government of the United States, some of them more than 150 years old.
If they try force to once again subdue the Lakotas.... Let's just say it will not end this time the way it ended before.
