On September 10, 2001, I delivered a presentation on terrorism and interagency coordination to an audience of American and Mexican military and government officials in Mexico City. My slide-deck, as it is known in military parlance, included images of the World Trade Towers and details of the 1993 truck-bomb attack, as well as open-source information on Osama Bin Laden. I had no special insight into the prophetic timing of my presentation, or of the magnitude of the events that would prove the resolve of both the perpetrators and targets of this infamous attack. There was, however, a foreshadowing regarding problems leading up to September 11th and which are present in most crisis events: the factors of trust and its impact on effective communication and coordination. I look back with a mix of emotions on the events of the following morning, because lack of unity and the silo-effect were contributing factors that plagued U.S. efforts to effectively develop a collaborative strategy of threat mitigation.
