Sun Tzu taught that strategic positions are both physical and psychological. Building a psychological position is easier than building a physical one because it is easier to manipulate information than it is to move real objects. For example, the war on terror has always been an information war. The main thesis of my adaptation of Sun Tzu to address the terror war, Strategy Against Terror, is that terrorism is best understood as a advertising campaign in which the terrorist leverage the systemic problems with mass media.
