Apparently international politics must be quiet at the moment; Foreign Policy had a lengthy piece on zombies this week: “Dawn of the Theories of International Politics and Zombies.”
Lots of research (facetiously, I hope) has gone into how society would react to a as-of-yet theoretical attack.
Key quote:
If bureaucratic conflicts and organizational pathologies hamper effective counter-terrorism policies, imagine the effect they would have on anti-zombie policies. The bureaucratic turf wars would be significant. Quelling the rise of the undead would require significant interagency coordination. In the United States, one could easily envisage major roles for the Departments of State, Defense, Justice, Homeland Security, Transportation, and Health and Human Services. This does not include autonomous or semi-autonomous agencies like the Federal Emergency Management Agency, Environmental Protection Agency, Food and Drug Administration, Center for Disease Control, and the myriad intelligence agencies.
So the ability of organizations to adapt to an army of the undead is an open question. Clearly, further research in this area is desperately needed.
