I see. I just wondered if there was a technical difference, because tribal sovereignty does seem to be more limited than what you would expect of a sovereign nation. We don't treat them like separate countries. They're not usually identified on maps of North America, for instance. And I get that most reservations are relatively small, but the Navajo Nation is about the size of Ireland, so plenty big enough to be identified on a map.

But I don't mean to interrogate you, I'm just curious about this topic. I think I'll do some research because I'd like to know more.
