Why should the title be Tsar? Even if the title is the President, if there are vast executive powers and there is no term limit, it is as good as an elective monarchy, isn't it? I think today the monarchy is confined to certain European countries, East and South East Asian countries and Middle East sheikhdoms. The dictators prefer to remain as Presidents and sometimes Presidents for life. Hereditary rule as in "Best Korea" is also possible. Title is no more important.
