We now have capabilities in science and technology that raise the very realistic possibility that a small group of terrorists could kill not only thousands of people, as they did on September 11th, but hundreds of thousands of people. And that has changed the dimension of the threat we face.

The fact that we have not had a terrorist attack in this country in the last six years is not a cause for complacency or a time to celebrate the end of the struggle. The threat is not going away. The enemy has not lost interest. ...Fundamentally, we're in a struggle about ideology. Terrorists want to remake the world in their own image and it is the image that is intolerant of the kinds of institutions that we cherish.

I'm sometimes asked why it is that for 30 years we seem to have trouble in the United States enforcing the rules against illegal immigration, and I'll tell you what the answer is. The answer is that when the television cameras turn off and the spotlight moves to something else, there are a host of interest groups and advocacy groups who work very, very hard to make it difficult to enforce these rules. I'm not commenting adversely on their motivation, but I can tell you the effect of all of this is to wear down the ability of an agency to enforce the law.

Even the kinds of ingredients you can find in your own kitchen can be used to make bombs. So the problem is with the people and not with the tools.

I think the idea that you can go this alone is - was a huge mistake. And unfortunately, there was a price paid in terms of suffering and pain for people in New Orleans.

But one thing that we have done in the last four years is we have really put pressure on the leadership of this organization [Al Qaeda]. We have killed a significant number of leaders. We've captured others. Those that remain have to look over their shoulders, they have to be on the run. So that even if we don't manage to kill or capture them all within four years, what we do do is put the kind of pressure on them that makes them focus on their own skins, as opposed to carrying out attacks.

You don't bargain with terrorists. You don't appease terrorists. And anybody who believes that this is about something we've done has to ask themselves why it is, on September 11, 2001, before we were in Afghanistan, before we were in Iraq, he committed a dastardly attack killing over 3,000 people. I mean, this is not a matter of negotiation; it's a matter of victory.
