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.

I have not heard a report of thousands of people in the convention center who don't have food and water.

And I have to say, I agree with some of the criticisms that some have made about that state program which allocates the grant money on a very rigid formula all across the country, with a certain percentage to each state.

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.

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.

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.

We don't really have the ability to enforce the law with respect to illegal work in this country in a way that's truly effective...We haven't been able to require every employer to enter a system in which they check the work status of their employees and determine whether they're legal, and without that, we don't really have the ability to enforce the law with respect to illegal work in this country in a way that's truly effective. And that would be the single greatest additional weapon we could use if we're serious about tackling this problem.
