In August 2009, Professor Drezner, who blogs for Foreign Policy magazine, wrote a short piece about how international relations theories might apply in the wake of a zombie apocalypse. Not only did Drezner do it very well, and in a manner that should make anyone familiar with IR theory chuckle, but it also opened up the possibility that those who automatically shudder at the word `theory' could actually understand and enjoy what Drezner was writing about, and gain an understanding of IR theory in the process. It was the perfect vehicle to bring a greater understanding of the theories that inform international interactions to a wider audience: it was fun, intelligent and quirky, and therefore likely to stick in one's mind. [As someone who has taught Intro to IR Theory, I can tell you that this is very important.]

Drezner's conclusions are brought together in a very concise final chapter that ably demonstrates the similarities, strengths and weaknesses of the theories he's discussed. He has hoped to show that when zombies walk the earth, it is not the end of humanity, and that international theory can offer a handle with which to approach this shambling threat.

Some of the jokes and references in this book might go a bit over some readers' heads, or may pass completely unnoticed, but only because the reader may not get the significance of some apparently-mundane phrases that are actually paraphrased `jargon' of the various theories. Despite this, however, there is no doubt that Drezner has written a book that is both fun and also academically sound. I am certain that the world can now breathe easy knowing that global governments might be just that little bit more prepared to deal with any future zombie apocalypse. This slim volume is very well-structured and written, and offers a superb introduction to not only zombie apocalypses, but also international relations theory.

I've been a fan of Drezner's writing ever since he started his blog on Foreign Policy. Reading Theories of International Politics and Zombies has only reinforced my respect for him and his work - he offers light humour to supplement his expert summaries and analysis. This review has only touched on a small fraction of how much the author has managed to cram into such a slim volume.

If you buy only one book about international relations (or zombies), make it this one. Very highly recommended, this is already one of my favourite books. It will change the way you watch zombie movies, and read zombie novels.
