September 12 was the first day of a new era, which America faced with a unified resolve, strengthened by a revived sense of patriotism and the goodwill and sympathy of the world. In retrospect, my country could have done so much with this opportunity. It could have treated terror not as the theological phenomenon it purported to be, but as the crime it was. It could have used this rare moment of solidarity to reinforce democratic values and cultivate resilience in the now-connected global public. Instead, it went to war.
