I am having trouble assuming good faith in your question. The Supreme Leader there is the son of the previous Supreme Leader who is the son of the Supreme Leader before him. One family has had absolute control over that nation for 3 generations, passing from father to son. Like the Ottoman Empire monarchy they have resolved the whole uncle vs son dilemma pretty brutally.
