Whatever connection there is between the US and the tribal nations, it is small, but the more connection there is, the better it is for those INDIAN tribes.

Colonizing the world has been perhaps the biggest BENEFIT that the colonized people ever had. Generally colonized people were of extremely low technology levels, and had their living standards raised immensely from European expansion to their lands.
No question that living standards for humans went up dramatically when white Europeans arrived here. The American Indians were so low technogically, they didn't even have the wheel, or even buildings. They lived in tents and mud huts. In Europe and the middle east, people were living in buildings (some of them palaces), for thousands of years already, when Europeans first arrived here in North America.
People crab about what Europeans did to American Indians, but how many
Indians living today would want to go back to living in tents right now, with snakes joining them during the night while they're asleep ? How many would give up their cars, TV sets, indoor heat, AC, indoor plumbing. Give up the computers, cellphones, stereos, and all the advances of modern medicine ?
European expansion is one of the best things that ever happened to those folks.
