Terrorists don’t think like army generals. Instead, they think like theater producers. The public memory of the 9/11 attacks testifies that everyone understands this intuitively. If you ask people what happened on 9/11, they are likely to say that al-Qaeda knocked down the twin towers of the World Trade Center. Yet the attack involved not merely the towers but two other actions, in particular a successful attack on the Pentagon. Why do fewer people remember that?
