Besides, it is kind of difficult to decide who really owns any land when you look back through the long and complicated history of just about any modern country. Who should own Argentina? It used force to separate itself from Spain, so should Spain still have a claim over it? Should they demand it back again? How did Spain get it in the first place? By conquering the place, which means it was stolen from the natives. Should the descendants of the natives claim it back? But then the natives no doubt were made up of tribes/groups that used force to change ownership. So are you going to work that out backwards to the first tribe to arrive in the area many thousands of years ago? Where do you draw the line? Given the complexity you pretty much end up with the fairest method being to ask the actual inhabitants who they want to govern them. They said they want the British.
