I think the aim - and certainly the aim of what I've tried to do since leaving - is not political and certainly not a witch hunt at individuals. It's to try to direct our attention at what I believe is a fundamental fault analysis that we must now examine.

The Germans certainly - the intelligence service believed that there were WMD. It turns out that we were all wrong, probably in my judgment, and that is most disturbing.

Both of us are known for probably at times regrettable streak of independence.

And let me take one of the explanations most commonly given: Analysts were pressured to reach conclusions that would fit the political agenda of one or another administration. I deeply think that is a wrong explanation.

The case of Iran, a nuclear program that the Iranians admit was 18 years on, that we underestimated. And, in fact, we didn't discover it. It was discovered by a group of Iranian dissidents outside the country who pointed the international community at the location.

And never - not in a single case - was the explanation, 'I was pressured to do this.' The explanation was very often, 'The limited data we had led one to reasonably conclude this. I now see that there's another explanation for it.'

I would also point out that many governments that chose not to support this war - certainly, the French president, Jacques Chirac, as I recall in April of last year, referred to Iraq's possession of WMD.

I came not from within the administration, and it was clear and clear in our discussions and no one asked otherwise that I would lead this the way I thought best and I would speak the truth as we found it.

I do believe we have to understand why reality turned out to be different than expectations and estimates. But you have more public service - certainly many of you - than I have ever had, and you recognize that this is not unusual.

There's a long record here of being wrong. There's a good reason for it. There are probably multiple reasons. Certainly proliferation is a hard thing to track, particularly in countries that deny easy and free access and don't have free and open societies.

Let me begin by saying, we were almost all wrong, and I certainly include myself here.

A great deal has been accomplished by the team, and I do think it important that it goes on and it is allowed to reach its full conclusion. In fact, I really believe it ought to be better resourced and totally focused on WMD; that that is important to do it.

This hearing came about very quickly. I do have a few preliminary comments, but I suspect you're more interested in asking questions, and I'll be happy to respond to those questions to the best of my ability.

And you know, almost in a perverse way, I wish it had been undue influence because we know how to correct that. We get rid of the people who, in fact, were exercising that.

And like I say, I think we've got other cases other than Iraq. I do not think the problem of global proliferation of weapons technology of mass destruction is going to go away, and that's why I think it is an urgent issue.

The Libyan program recently discovered was far more extensive than was assessed prior to that.

But the most important thing about that story, which is not often told, is that as a result after the Cuban missile crisis, immediate steps were taken to correct our inability to collect on the movement of nuclear material out of the Soviet Union to other places.

I had innumerable analysts who came to me in apology that the world that we were finding was not the world that they had thought existed and that they had estimated. Reality on the ground differed in advance.

I think the aim - and certainly the aim of what I've tried to do since leaving - is not political and certainly not a witch hunt at individuals. It's to try to direct our attention at what I believe is a fundamental fault analysis that we must now examine.

I've seen looting around the world and thought I knew the best looters in the world. The Iraqis excel at that.

But I do think the survey group - and I think Charlie Duelfer is a great leader. I have the utmost confidence in Charles. I think you will get as full an answer as you can possibly get.

As leader of the effort of the Iraqi Survey Group, I spent most of my days not out in the field leading inspections. It's typically what you do at that level. I was trying to motivate, direct, find strategies.

Fortunately, President Kennedy and Robert Kennedy disagreed with the estimate and chose a course of action less ambitious and aggressive than recommended by their advisers.

The fact that it wasn't tells me that we've got a much more fundamental problem of understanding what went wrong, and we've got to figure out what was there. And that's what I call fundamental fault analysis.

The result is - document destruction - we're really not going to be able to prove beyond a truth the negatives and some of the positive conclusions that we're going to come to. There will be always unresolved ambiguity here.

In my judgment, based on the work that has been done to this point of the Iraq Survey Group, and in fact, that I reported to you in October, Iraq was in clear violation of the terms of U.N.Resolution 1441.

Sen. Edward Kennedy knows very directly. Senator Kennedy and I talked on several occasions prior to the war that my view was that the best evidence that I had seen was that Iraq indeed had weapons of mass destruction.

I also believe that it is time to begin the fundamental analysis of how we got here, what led us here and what we need to do in order to ensure that we are equipped with the best possible intelligence as we face these issues in the future.

I think that shows a level of maturity and understanding that I think bodes well for getting to the bottom of this. But it is really up to you and your staff, on behalf of the American people, to take on that challenge.

The bronze powder business, however, no longer required my personal attention, and was well managed by those I had chosen as the guardians of a secret, which was long and honourably kept.

The kinds of shows that seem to work now, the comedy shows, are those which require very little attention. They're superficial and I like articulate comedy.

The constant attention is what is so difficult.

As a scientist, my attention became totally focused on global warming some 15 years ago by the elegant and powerful measurements of carbon dioxide trapped in ice cores taken as much as 2 miles deep from the great East Antarctica ice sheet.

Anytime you have a difficult encounter with your child, there is a good chance that at least one of these factors is bringing out the worst in him or her: transitions, time pressure, competition for your attention, conflicting objectives.

I think it would have been a lot better for him to say, I did it and I'm sorry, McGwire was never one to show a lot of emotion on the field, not a player who sought attention and craved to be thought of as a nice guy.

I wanted to write a story that demanded the viewer's attention.

After some minor pieces of theoretical study that I worked on, a student in my statistical mechanics class brought to my attention a problem in polyelectrolytes.

I don't want to come off like the jealous brother who wasn't getting the attention, but it was like no one was really into me anyway. I wasn't really a priority.

If particular care and attention is not paid to the ladies, we are determined to foment a rebellion, and will not hold ourselves bound by any laws in which we have no voice, or representation.

There's a lot of other movies I like, but I don't even pay attention to directors to tell you the truth.

The genius of the economic machine is in its ability to convert these indulgences into profitability. It converts desire into attention, a grip on our eyeballs and eardrums, which in turn can be marketed to advertisers.

The police are the public and the public are the police; the police being only members of the public who are paid to give full time attention to duties which are incumbent on every citizen in the interests of community welfare and existence.

The writer should never be ashamed of staring. There is nothing that does not require his attention.

The poet produces the beautiful by fixing his attention on something real.

The nation did not begin to realize the extraordinary possibilities of the vast Western territory until its attention was thus suddenly and definitely concentrated on the Pacific by the annual addition of over fifty million dollars to the circulating medium.

Movies absorb our attention more completely, I think.

I guess because I pay so much attention to the physical part of the character, I don't look upon it as like Charlize Theron up there. I don't think of them as like Charlize Theron films.

They cannot count on the press and they cannot count on Congressional committees to bring the problems of the scientific community to their own attention, or to police the scientific community.

The difference between something good and something great is attention to detail.
