While hardly a great book, it is still worth the small investment of time required to read it. "The Age of the Unthinkable", by Joshua Ramo focuses on complexity, rapid change, and concludes we can't predict or prevent all future threats, so our strategy should be focused on resilience. In other words designing a political/economic/social structure that can survive and continue to thrive in the unavoidable 9/11 like events in the future. Hardly a complete strategy, but resilience should definitely be a component of our national strategy. Especially since the trend enabled by technology is greater centralization of critical infrastructure, because it is cost efficient, but it makes us increasingly vulnerable. One example is our power grid.

I found this book to be a good supplement to the Joint Operational Environment (the JOE) published by JFCOM, and it also sounds like it would nest nicely with the "The American Culture of War", which I haven't read yet (but intend to).
