On the morning of September 11, 2001, special operations units of the international jihadist group Al Qaeda struck the United States. In a classic opening attack, they struck simultaneously at the political, military, and financial centers of the United States. The attack on the political centers failed entirely when the aircraft assigned to that mission crashed prematurely in Pennsylvania. The attack on the military center was only partially successful. The aircraft assigned to that target crashed into a section of the Pentagon that had been modernized with fire-resistant materials, which effectively contained the explosion. The planes assigned to attack the U.S. financial center succeeded completely, not only destroying the World Trade Center towers but closing down the financial markets for several days and disrupting the U.S. economy.
The nineteen men who carried out the mission were capable operatives. Their achievement was not taking control of four airliners simultaneously, although that was not a trivial accomplishment. Rather, it was planning, training, and deploying for the operation without ever being detected by American intelligence-or, more precisely, acting in such a way that in spite of inevitable detection, the data never congealed into actionable intelligence. While their military capabilities were enormously inferior to those of the United States-they had to steal an air force-their skills at covert operations were superb.
Al Qaeda had spent years trying to understand how U.S. intelligence worked. On September 9, the Sunday before the attack, Osama bin Laden, by most accounts, placed a phone call to his mother. During the short conversation, Osama told her, in effect, "In two days you're going to hear big news, and you're not going to hear from me for a while." He placed that call on Sunday knowing that it would be intercepted by National Security Agency signal intelligence satellites. He also knew that the intercept-interpret-analyze cycle at the NSA for the region was running at about seventy-two hours. He knew that by the time the phone call was actually listened to and understood, the attack would already have taken place.
This was the real strength of Al Qaeda, a strength that it retains to this day. It understands the craft of intelligence and security and applies it rigorously. But Al Qaeda has another strength. The nineteen men who launched the attack on September 11 were not just prepared to risk their lives. They were prepared to go to their certain deaths and did so exercising discipline and control until the moment they died.
If Al Qaeda consisted of simplistic incompetents, the United States would not be in the global war it is embroiled in today. Fools do not make serious opponents. The challenge posed by Al Qaeda is that they are neither simple nor incompetents. However we judge their beliefs and however we evaluate their morality, the fact is that from a technical standpoint, they proved themselves to be highly competent covert operators.
