Do tell what you think is the criteria for a country being one. Is Transnistria one? South Ossetia? Taiwan? A native American tribe? The US? An American state? It's a trick question!

A native American tribe is a nation, by definition [1]. Heck, the Canadians call theirs "First Nations".

A country requires sovereignty over some land, people, and international recognition. Without the last part, Sealand was a country. Funnily enough, depending on how strict you're with the criteria, some native American tribes are countries, and the US isn't always one due to reservations and states sovereignties.
