A conversation with Dan Drezner of Tufts University, who proposes a mesmerizing rethink of 21st foreign policy schools in terms of how each weighty discipline would confront populations of re-animated, flesh-eating corpses, the Undead, who are both predatory and not too bright (below, George Romero's 1968 Zombie classic, "Night of the Living Dead").  Dan Drezner's forthcoming book, "Theories of International Politics and Zombies," will be published by Princeton University Press at the end of the year.  We discuss the Obama administration's Realist School of diplomatic engagement seeking common grounds with zombies, the Nixon-era Liberal School of co-existence with zombies, the Bush administration's Neoconservative School of zombie-obliterating, and the challenges with failed states such as fractured Zombie Somalia or rogue states such as nuke-armed Zombie Iran.   We confront the many contradictions of zombie movies and legends, such as their limited intelligence, their command and control, the specific ways to destroy zombies, and the paradox of zombies with nuke weapons: would they use them, does nuking human civilization satisfy the zombie desire to eat living people?  And if humans nuke zombies in return, have they not created, outside the immediate blast area, a worse alternative, radioactive flesh-eaters?  (Listen Here)
