The 'stolen land' thing has always been a Bad Liberal Argument™ in the first place (based on exploiting the psychology of guilt in western people). If you look at any area of land on earth and you go back far enough you can always find it was occupied by someone else. Other peoples inhabited North America before who we think of as the native americans. In the end it's only the law of the jungle that matters. Might makes right. Whoever conquers a land has ownership of it until they are no longer able to defend it. Claims to land are worthless without force. Violence and competition are beneficial for the evolution of man and in keeping with the deeper universal principles.
