We are currently in a war, but it is not a war on terrorism. In fact, that has been a great confusion, and the sooner we drop that term, the better. This would be like President Franklin Roosevelt saying in World War II, "We are engaged in a war against kamikazes and blitzkrieg." Like them, terrorism is a method, a tool, a weapon that has been used against us. And part of the reason we suffered such a horrific attack is that we were not prepared. Let's not kid ourselves. Some very smart people defeated every single defense this country had, and defeated them easily, with confidence and arrogance. There are many lessons we must learn from this.

We were not prepared intellectually. Those of us in the national security field still carried the baggage of the Cold War. We thought in concepts of coalition warfare and the Warsaw Pact. When we thought of terrorism, we thought only of state-sponsored terrorism, which is why the immediate reaction of many in our government agencies after 9/11 was: Which state did it? Saddam, it must have been Saddam. We had failed to grasp, for a variety of reasons, the new phenomenon that had emerged in the world. This was not state-sponsored terrorism. This was religious war.

This was the emergence of a transnational enemy driven by religious fervor and fanaticism. Our enemy is not terrorism. Our enemy is violent, Islamic fundamentalism. None of our government institutions was set up with receptors, or even vocabulary, to deal with this. So we left ourselves completely vulnerable to a concerted attack.

Where are we today? I'd like to say we have fixed these problems, but we haven't. We have very real vulnerabilities. We have not diminished in any way the fervor and ideology of our enemy. We are fighting them in many areas of the world, and I must say with much better awareness of the issues and their nature. We're fighting with better tools. But I cannot say we are now safe from the kind of attack we saw on 9/11. I think we are much safer than we were on 9/11; the ability of our enemies to launch a concerted, sophisticated attack is much less than it was then. Still, we're totally vulnerable to the kinds of attacks we've seen in Madrid, for instance. We face a very sophisticated and intelligent enemy who has been trained, in many cases, in our universities and gone to school on our methods, learned from their mistakes, and continued to use the very nature of our free society and its aversion to intrusion in privacy and discrimination to their benefit...

We have seen throughout the last 20 years a kind of head-in-the-sand approach to national security in the Pentagon. We were comfortable with the existing concept of what the threat was, what threat analysis was, and how we derived our requirements, still using the same old tools we all grew up with. We paid no attention to the real nature of this emerging threat, even though there were warning signs. Many will recall with pain what we went through in the Reagan administration in 1983, when the Marine barracks were bombed in Beirut—241 Marines and Navy corpsmen were killed. We immediately got an intercept from NSA [National Security Agency], a total smoking gun from the foreign ministry of Iran, ordering the murder of our Marines. Nothing was done to retaliate. Instead, we did exactly what the terrorists wanted us to do, which was to withdraw. Osama bin Laden has cited this as one of his dawning moments. The vaunted United States is a paper tiger; Americans are afraid of casualties; they run like cowards when attacked; and they don't even bother to take their dead with them...
