There is a big difference between small nomadic tribes and established nations with settlements that are 5,000 years old. Still, restitution has been made to the various Indian tribes in the form of autonomous reservations, many of which are quite profitable.
Will the British be providing restitution to the Irish for centuries of oppression?
Really? Its OK to commit genocide (your word) against "nomadic tribes"? Of course given that the Celtic Irish were, well into Tudor times, largely a herding people, following their cattle from summer pastures, to winter pastures, and back, with the seasons, your comment reveals not only your moral bankruptcy, but your historical ignorance. Try again.
