...if you got a gun, shoot 'em in the head. That's the sure way to kill 'em. If you don't, get yourself a club, beat 'em or burn 'em. They go up pretty easy.

While traditional zombie narratives tend to end in apocalypse, most...theoretical approaches...suggested vigorous policy responses should we be attacked by the living dead.  Realists would push for a live-and-let-live arrangement between the undead and everyone else.  Liberals would call for an imperfect but useful global governing body to regulate the undead -- a World Zombie Organization.  Constructivists would call for a robust, pluralistic security community dedicated to preventing new zombie outbreaks and socializing existing zombies into human society.  Bureaucrats would very likely err in their initial response, but they'd adapt.
