I think they're in the last throes, if you will, of the insurgency.

It’s clearly established in terms of training, provision of bomb-making experts, training of people with respect to chemical and biological warfare capabilities, that al-Qaeda sent personnel to Iraq for training and so forth.

And the fact of the matter is there were thousands of people that went through those training camps in Afghanistan. We know they are seeking deadlier weapons - chemical, biological and nuclear weapons if they can get it.

The important thing here to understand is that the people that are at Guantanamo are bad people. I mean, these are terrorists for the most part. These are people that were captured in the battlefield of Afghanistan or rounded up as part of the Al Qaeda network. We've already screened the detainees there and released a number, sent them back to their home countries. But what's left is hard core.

I got to be White House chief of staff, ten years of congressman, secretary of defense, vice-president. If you're a political junkie like I obviously am - that was - every one of those was just a tremendous experience. I'm very comfortable with what I did and why I did it and how I did it. And I'll let others judge whether they liked it or not.

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.

We believe he has, in fact, reconstituted nuclear weapons.
