Can axj nations naciones de axj legally create an independent state in the usa?

This group has been created to unite all 55 recognized native American Tribes in North American and the largest Tribes in Central and South America including Amazons, Mayans, Aztecs, Incans, and Patagonians. AXJ ® proposes to create an AXJ ® Nation among them and mint gold coin from Peru and establish its unique wealth and employment creation systems.

We at AXJ ® around the world have already seen what local corrupt governments have done to our people in America since 1492, and have decided to unite and create our own State on American soil.

Is there any legal problem with that?

PAX VOBISCVM.
