 By this he means that the anarchical structure that neo-realists claim governs state interaction is in fact a phenomenon that is socially constructed and reproduced by states.For example, if the system is dominated by states that see anarchy as a life or death situation (what Wendt terms a "Hobbesian" anarchy) then the system will be characterized by warfare.If on the other hand anarchy is seen as restricted (a "Lockean" anarchy) then a more peaceful system will exist.
