We have to deal with this new type of threat in a way we haven’t yet defined. . . . With a low-probability, high-impact event like this . . . If there’s a one percent chance that Pakistani scientists are helping al Qaeda build or develop a nuclear weapon, we have to treat it as a certainty in terms of our response.

If we're successful in Iraq ... we will have struck a major blow right at the heart of the base, if you will, the geographic base of the terrorists who have had us under assault now for many years, but most especially on 9/11.

I have argued in the past, and would again, if we had been able to pre-empt the attacks of 9/11 would we have done it? And I think absolutely. We have to be prepared now to take the kind of bold action that's being contemplated with respect to Iraq in order to ensure that we don't get hit with a devastating attack when the terrorists' organization gets married up with a rogue state that's willing to provide it with the kinds of deadly capabilities that Saddam Hussein has developed and used over the years.

Once we got hit by - on 9/11 and lost 3,000 people that day, we recognized, and it was one of the key decisions President Bush made, that this is not a law enforcement problem, it is a strategic threat to the United States. It's a war. And based on that, we then adopted a whole set of policies that flowed out of that proposition.

I think, in fact, the situation with respect to al Qaeda, to say that, you know, that was a big attack we had on 9/11, but it's not likely again, I just think that's dead wrong. I think the biggest strategic threat the United States faces today is the possibility of another 9/11 with a nuclear weapon or a biological agent of some kind. And I think al Qaeda is out there even as we meet, trying to figure out how to do that.

The plan was criticized by some retired military officers embedded in TV studios. But with every advance by our coalition forces, the wisdom of that plan becomes more apparent.

Had the decision belonged to Senator Kerry, Saddam Hussein would still be in power today in Iraq. In fact, Saddam Hussein would almost certainly still be in control of Kuwait.
