Theories of International Politics and Zombies

Read this the other day after I saw it mentioned somewhere and just loved the idea. What do the competing theories of international relations have to say about a zombie apocalypse?
“Realism posits an eventual live-and-let-live arrangement between the undead and everyone else. Liberals predict an imperfect but useful counter-zombie regime. Neoconservatives believe that an aggressive and thorough military deployment would keep the undead menace at bay. Some constructivists would predict a robust pluralistic security community dedicated to preventing new zombie outbreaks and socializing existing zombies into human society.
However, bureaucratic dysfunction could trigger a total collapse in state authority. Public opinion and interest group pressure could make multilateral cooperation more difficult. And a norm cascade could trigger a world in which the biological distinctions between humans and zombies would be immaterial - everyone would act like zombies.”
