The status of any nation, and indeed any institution, is defined both by its power and its legitimacy. Power does not necessarily extend legitimacy, either to a state or an institution, nor does legitimacy in itself confer power.  It used to be claimed by Western analysts during the Cold War that while democratic Western societies had acquired both power and legitimacy, non-democratic nations may have power but do not enjoy international legitimacy.

An authoritarian, totalitarian or fascist state may command power but in the modern world it lacks legitimacy. Recent trends within democratic nations have brought this claim into question.
