"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.

Lakota country includes parts of the states of Nebraska, South Dakota, North Dakota, Montana and Wyoming.

The new country would issue its own passports and driving licences, and living there would be tax-free -- provided residents renounce their US citizenship, Means said.

The treaties signed with the United States are merely "worthless words on worthless paper," the Lakota freedom activists say on their website.

The treaties have been "repeatedly violated in order to steal our culture, our land and our ability to maintain our way of life," the reborn freedom movement says.

Withdrawing from the treaties was entirely legal, Means said.

"This is according to the laws of the United States, specifically article six of the constitution," which states that treaties are the supreme law of the land, he said.

"It is also within the laws on treaties passed at the Vienna Convention and put into effect by the US and the rest of the international community in 1980. We are legally within our rights to be free and independent," said Means.

The Lakota relaunched their journey to freedom in 1974, when they drafted a declaration of continuing independence -- an overt play on the title of the United States' Declaration of Independence from England.

Thirty-three years have elapsed since then because "it takes critical mass to combat colonialism and we wanted to make sure that all our ducks were in a row," Means said.
