Most of all, we need to see that the landscape of reality is altered. In the past, we've fought ideological movements that took control of states. Our foreign policy apparatus is geared toward relations with states: negotiating with states, confronting states. Now we are faced with a belief system that is inimical to the state system, and aims at theological rule and the restoration of the caliphate. We'll need a new set of institutions to grapple with this reality, and a new training method to understand people who are uninterested in national self-interest, traditionally defined.
Last week I met with a leading military officer stationed in Afghanistan and Iraq, whose observations dovetailed remarkably with the 9/11 commissioners. He said the experience of the last few years is misleading; only 10 percent of our efforts from now on will be military. The rest will be ideological. He observed that we are in the fight against Islamic extremism now where we were in the fight against communism in 1980.
