Naruto's goal is to surpass all the hokage's and become teh greatest of them all.
so here is a thought, since the world will be in peace after the war. maybe Naruto will become an alpha-hokage, meaning he will be the one>all kages, meaning his word is law. he will basically be a person who will wonder between all 5 nations as a force of justice, ruler and leader of all the ninja's and like the S06p keep gaining power and protect everything he loves.
what do you think?
