Ontological Security in International Relations inspires a number of ideas, and as such, there are a number of potential future applications for Steele's ontological security approach. What Sjoberg has illustrated with regards to feminism may be equally applicable to other IR theories. For instance, Steele has a number of interesting insights regarding hegemony, suggesting that the ontological security research program might have ramifications for such approaches as hegemonic stability theory. The issue of self-interrogation and the case of the Zero Dark Thirty controversy also needs further attention. To flesh some of these (and other) ideas and applications out, there is no doubt that Steele's book is worthy of further attention. Luke M. Herrington, E-IR
