Among the many distortions, misrepresentations and outright falsifications that have emerged from the debate over Iraq, one in particular stands out above all others. This is the charge that George W. Bush misled us into an immoral or unnecessary war in Iraq by telling a series of lies that have now been definitively exposed.

What makes this charge so special is the amazing success it has enjoyed in getting itself established as a self-evident truth even though it has been refuted and discredited over and over again by evidence and argument alike. In this it resembles nothing so much as those animated cartoon characters who, after being flattened, blown up or pushed over a cliff, always spring back to life with their bodies perfectly intact. Perhaps, like those cartoon characters, this allegation simply cannot be killed off, no matter what.

Nevertheless, I want to take one more shot at exposing it for the lie that it itself really is. Although doing so will require going over ground that I and many others have covered before, I hope that revisiting this well-trodden terrain may also serve to refresh memories that have grown dim, to clarify thoughts that have grown confused, and to revive outrage that has grown commensurately dulled.

This entire scenario of purported deceit was given a new lease on life by the indictment in late October of I. Lewis "Scooter" Libby, then chief of staff to Vice President Dick Cheney. Mr. Libby stands accused of making false statements to the FBI and of committing perjury in testifying before a grand jury that had been convened to find out who in the Bush administration had "outed" Valerie Plame, a CIA agent married to the retired ambassador Joseph C. Wilson IV. The supposed purpose of leaking this classified information to the press was to retaliate against Mr. Wilson for having "debunked" (in his words) "the lies that led to war."

Now, as it happens, Mr. Libby was not charged with having outed Ms. Plame but only with having lied about when and from whom he first learned that she worked for the CIA. Moreover, Patrick J. Fitzgerald, the special prosecutor who brought the indictment against him, made a point of emphasizing that "this indictment is not about the war":

This indictment is not about the propriety of the war. And people who believe fervently in the war effort, people who oppose it, people who have mixed feelings about it should not look to this indictment for any resolution of how they feel or any vindication of how they feel.

This is simply an indictment that says, in a national-security investigation about the compromise of a CIA officer's identity that may have taken place in the context of a very heated debate over the war, whether some person--a person, Mr. Libby--lied or not.

This case is bigger than the leak of classified information. It is about how the Bush White House manufactured and manipulated intelligence in order to bolster its case for the war in Iraq and to discredit anyone who dared to challenge the president.

How indeed could it have been otherwise? George Tenet, his own CIA director, assured him that the case was "a slam dunk." This phrase would later become notorious, but in using it, Mr. Tenet had the backing of all 15 agencies involved in gathering intelligence for the United States. In the National Intelligence Estimate of 2002, where their collective views were summarized, one of the conclusions offered with "high confidence" was that "Iraq is continuing, and in some areas expanding its chemical, biological, nuclear, and missile programs contrary to UN resolutions."

The intelligence agencies of Britain, Germany, Russia, China, Israel and--yes--France all agreed with this judgment. And even Hans Blix--who headed the U.N. team of inspectors trying to determine whether Saddam had complied with the demands of the Security Council that he get rid of the weapons of mass destruction he was known to have had in the past--lent further credibility to the case in a report he issued only a few months before the invasion:

The discovery of a number of 122-mm chemical rocket warheads in a bunker at a storage depot 170 km [105 miles] southwest of Baghdad was much publicized. This was a relatively new bunker, and therefore the rockets must have been moved there in the past few years, at a time when Iraq should not have had such munitions. . . . They could also be the tip of a submerged iceberg. The discovery of a few rockets does not resolve but rather points to the issue of several thousands of chemical rockets that are unaccounted for.

I can't tell you why the French, the Germans, the Brits and us thought that most of the material, if not all of it, that we presented at the U.N. on 5 February 2003 was the truth. I can't. I've wrestled with it. [But] when you see a satellite photograph of all the signs of the chemical-weapons ASP--Ammunition Supply Point--with chemical weapons, and you match all those signs with your matrix on what should show a chemical ASP, and they're there, you have to conclude that it's a chemical ASP, especially when you see the next satellite photograph which shows the UN inspectors wheeling in their white vehicles with black markings on them to that same ASP, and everything is changed, everything is clean. . . . But George [Tenet] was convinced, John McLaughlin [Tenet's deputy] was convinced, that what we were presented [for Powell's UN speech] was accurate.

People say, well, INR dissented. That's a bunch of bull. INR dissented that the nuclear program was up and running. That's all INR dissented on. They were right there with the chems and the bios.

Iraq's efforts to acquire aluminum tubes [which are] central to the argument that Baghdad is reconstituting its nuclear-weapons program. . . . INR is not persuaded that the tubes in question are intended for use as centrifuge rotors . . . in Iraq's nuclear-weapons program.

The French came in in the middle of my deliberations at the CIA and said, we have just spun aluminum tubes, and by God, we did it to this rpm, et cetera, et cetera, and it was all, you know, proof positive that the aluminum tubes were not for mortar casings or artillery casings, they were for centrifuges. Otherwise, why would you have such exquisite instruments?

Additional confirmation of this latter point comes from Kenneth Pollack, who served in the National Security Council under Clinton. "In the late spring of 2002," Pollack has written:

I participated in a Washington meeting about Iraqi WMD. Those present included nearly twenty former inspectors from the United Nations Special Commission (UNSCOM), the force established in 1991 to oversee the elimination of WMD in Iraq. One of the senior people put a question to the group: did anyone in the room doubt that Iraq was currently operating a secret centrifuge plant? No one did. Three people added that they believed Iraq was also operating a secret calutron plant (a facility for separating uranium isotopes).

If Saddam rejects peace and we have to use force, our purpose is clear. We want to seriously diminish the threat posed by Iraq's weapons-of-mass-destruction program.

Iraq is a long way from [the USA], but what happens there matters a great deal here. For the risk that the leaders of a rogue state will use nuclear, chemical, or biological weapons against us or our allies is the greatest security threat we face.

He will use those weapons of mass destruction again, as he has ten times since 1983.

Nor did leading Democrats in Congress entertain any doubts on this score. A few months after Mr. Clinton and his people made the statements I have just quoted, a group of Democratic senators, including such liberals as Carl Levin, Tom Daschle, and John Kerry, urged the President "to take necessary actions (including, if appropriate, air and missile strikes on suspect Iraqi sites) to respond effectively to the threat posed by Iraq's refusal to end its weapons-of-mass-destruction programs."

Nancy Pelosi, the future leader of the Democrats in the House, and then a member of the House Intelligence Committee, added her voice to the chorus:

Saddam Hussein has been engaged in the development of weapons-of-mass-destruction technology, which is a threat to countries in the region, and he has made a mockery of the weapons inspection process.

There is no doubt that . . . Saddam Hussein has invigorated his weapons programs. Reports indicate that biological, chemical, and nuclear programs continue apace and may be back to pre-Gulf war status. In addition, Saddam continues to redefine delivery systems and is doubtless using the cover of a licit missile program to develop longer-range missiles that will threaten the United States and our allies.

Saddam Hussein is a tyrant and a threat to the peace and stability of the region. He has ignored the mandate of the United Nations, and is building weapons of mass destruction and the means of delivering them.

In the four years since the inspectors left, intelligence reports show that Saddam Hussein has worked to rebuild his chemical- and biological-weapons stock, his missile-delivery capability, and his nuclear program. He has also given aid, comfort, and sanctuary to terrorists, including al-Qaeda members.

There is unmistakable evidence that Saddam Hussein is working aggressively to develop nuclear weapons and will likely have nuclear weapons within the next five years. . . . We also should remember we have always underestimated the progress Saddam has made in development of weapons of mass destruction.

We know that [Saddam] has stored secret supplies of biological and chemical weapons throughout his country.

Iraq's search for weapons of mass destruction has proven impossible to deter, and we should assume that it will continue for as long as Saddam is in power.

I will be voting to give the President of the United States the authority to use force--if necessary--to disarm Saddam Hussein because I believe that a deadly arsenal of weapons of mass destruction in his hands is a real and grave threat to our security.

Kennedy: "We have known for many years that Saddam Hussein is seeking and developing weapons of mass destruction."

Byrd: "The last U.N. weapons inspectors left Iraq in October of 1998. We are confident that Saddam Hussein retains some stockpiles of chemical and biological weapons, and that he has since embarked on a crash course to build up his chemical- and biological-warfare capabilities. Intelligence reports indicate that he is seeking nuclear weapons."

The Times was also skeptical of negotiations, pointing out that it was "hard to negotiate with a tyrant who has no intention of honoring his commitments and who sees nuclear, chemical, and biological weapons as his country's salvation."

So, too, the Washington Post, which greeted the inauguration of George W. Bush in January 2001 with this admonition:

Of all the booby traps left behind by the Clinton administration, none is more dangerous--or more urgent--than the situation in Iraq. Over the last year, Mr. Clinton and his team quietly avoided dealing with, or calling attention to, the almost complete unraveling of a decade's efforts to isolate the regime of Saddam Hussein and prevent it from rebuilding its weapons of mass destruction. That leaves President Bush to confront a dismaying panorama in the Persian Gulf [where] intelligence photos . . . show the reconstruction of factories long suspected of producing chemical and biological weapons.

All this should surely suffice to prove far beyond any even unreasonable doubt that Mr. Bush was telling what he believed to be the truth about Saddam's stockpile of WMD. It also disposes of the fallback charge that Mr. Bush lied by exaggerating or hyping the intelligence presented to him. Why on earth would he have done so when the intelligence itself was so compelling that it convinced everyone who had direct access to it, and when hardly anyone in the world believed that Saddam had, as he claimed, complied with the 16 resolutions of the Security Council demanding that he get rid of his weapons of mass destruction?

The March 2005 report of the equally bipartisan Robb-Silberman commission, which investigated intelligence failures on Iraq, reached the same conclusion, finding "no evidence of political pressure to influence the intelligence community's pre-war assessments of Iraq's weapons programs. . . . Analysts universally asserted that in no instance did political pressure cause them to skew or alter any of their analytical judgments."

Still, even many who believed that Saddam did possess WMD, and was ruthless enough to use them, accused Mr. Bush of telling a different sort of lie by characterizing the risk as "imminent." But this, too, is false: Mr. Bush consistently rejected imminence as a justification for war. Thus, in the State of the Union address he delivered only three months after 9/11, Mr. Bush declared that he would "not wait on events while dangers gather" and that he would "not stand by, as peril draws closer and closer." Then, in a speech at West Point six months later, he reiterated the same point: "If we wait for threats to materialize, we will have waited too long." And as if that were not clear enough, he went out of his way in his State of the Union address in 2003 (that is, three months before the invasion), to bring up the word "imminent" itself precisely in order to repudiate it:

Some have said we must not act until the threat is imminent. Since when have terrorists and tyrants announced their intentions, politely putting us on notice before they strike? If this threat is permitted to fully and suddenly emerge, all actions, all words, and all recriminations would come too late. Trusting in the sanity and restraint of Saddam Hussein is not a strategy, and it is not an option.

The story begins with the notorious 16 words inserted--after, be it noted, much vetting by the CIA and the State Department--into Bush's 2003 State of the Union address:

The British government has learned that Saddam Hussein recently sought significant quantities of uranium from Africa.

My husband has good relations with the PM [the prime minister of Niger] and the former minister of mines . . ., both of whom could possibly shed light on this sort of activity.

In response, the White House, no doubt hoping to prevent his allegation about the 16 words from becoming a proxy for the charge that (in Mr. Wilson's latest iteration of it) "lies and disinformation [were] used to justify the invasion of Iraq," eventually acknowledged that the president's statement "did not rise to the level of inclusion in the State of the Union address." As might have been expected, however, this panicky response served to make things worse rather than better. And yet it was totally unnecessary--for the maddeningly simple reason that every single one of the 16 words at issue was true.

That is, British intelligence had assured the CIA that Saddam Hussein had tried to buy enriched uranium from the African country of Niger. Furthermore--and notwithstanding the endlessly repeated assertion that this assurance has now been discredited--Britain's independent Butler commission concluded that it was "well-founded." The relevant passage is worth quoting at length:

a. It is accepted by all parties that Iraqi officials visited Niger in 1999.

b. The British government had intelligence from several different sources indicating that this visit was for the purpose of acquiring uranium. Since uranium constitutes almost three-quarters of Niger's exports, the intelligence was credible.

c. The evidence was not conclusive that Iraq actually purchased, as opposed to having sought, uranium, and the British government did not claim this.

He [the CIA reports officer] said he judged that the most important fact in the report [by Mr. Wilson] was that Niger officials admitted that the Iraqi delegation had traveled there in 1999, and that the Niger prime minister believed the Iraqis were interested in purchasing uranium.

The report on [Mr. Wilson's] trip to Niger . . . did not change any analysts' assessments of the Iraq-Niger uranium deal. For most analysts, the information in the report lent more credibility to the original CIA reports on the uranium deal.

The liar here, then, was not Mr. Bush but Mr. Wilson. And Mr. Wilson also lied when he told the Washington Post that he had unmasked as forgeries certain documents given to American intelligence (by whom it is not yet clear) that supposedly contained additional evidence of Saddam's efforts to buy uranium from Niger. The documents did indeed turn out to be forgeries; but, according to the Butler report:

The forged documents were not available to the British government at the time its assessment was made, and so the fact of the forgery does not undermine [that assessment].

[Mr. Wilson] also told committee staff that he was the source of a Washington Post article . . . which said, "among the envoy's conclusions was that the documents may have been forged because 'the dates were wrong and the names were wrong.' " Committee staff asked how the former ambassador could have come to the conclusion that the "dates were wrong and the names were wrong" when he had never seen the CIA reports and had no knowledge of what names and dates were in the reports.

So much for the author of the best-selling and much-acclaimed book whose title alone--"The Politics of Truth: Inside the Lies that Led to War and Betrayed My Wife's CIA Identity"--has set a new record for chutzpah.

And so long as we are hunting for liars in this area, let me suggest that we begin with the Democrats now proclaiming that they were duped, and that we then broaden out to all those who in their desperation to delegitimize the larger policy being tested in Iraq--the policy of making the Middle East safe for America by making it safe for democracy--have consistently used distortion, misrepresentation and selective perception to vilify as immoral a bold and noble enterprise and to brand as an ignominious defeat what is proving itself more and more every day to be a victory of American arms and a vindication of American ideals.
