If we're unwinding back almost 200 years to reach that conclusion, why not go 600? Have you appropriately compensated the native Argentinian tribes for the natural resources that you have plundered from them?
We are? Do people in "prehistoric societies" (whatever that is supposed to mean) not have rights to territory, or to natural resources?
In any case, I was definitely talking about people, not countries - this is clearly spelled out in the comment that started this thread. I don't care about countries. They only exist to serve the people, and any such rights they claim above and beyond that are illegitimate.
