THE BURNED OVER DISTRICT

One of the most influential Iraqi "sources" in the run-up to Georgies Little War was also one of the most fraudulent, and the White House knew it.The story is long, detailed and scary.

Five senior officials from Germany's Federal Intelligence Service, or BND, said in interviews with The Times that they warned U.S. intelligence authorities that the source, an Iraqi defector code-named Curveball, never claimed to produce germ weapons and never saw anyone else do so.

According to the Germans, President Bush mischaracterized Curveball's information when he warned before the war that Iraq had at least seven mobile factories brewing biological poisons. Then-Secretary of State Colin L. Powell also misstated Curveball's accounts in his prewar presentation to the United Nations on Feb. 5, 2003, the Germans said.

Curveball's German handlers for the last six years said his information was often vague, mostly secondhand and impossible to confirm.

"This was not substantial evidence," said a senior German intelligence official. "We made clear we could not verify the things he said."

The German authorities, speaking about the case for the first time, also said that their informant suffered from emotional and mental problems. "He is not a stable, psychologically stable guy," said a BND official who supervised the case. "He is not a completely normal person," agreed a BND analyst.

Knowing this from the Germans, what did Our Dear Embattled Leader and his minions do?

The White House, for example, ignored evidence gathered by United Nations weapons inspectors shortly before the war that disproved Curveball's account. Bush and his aides issued increasingly dire warnings about Iraq's biological weapons before the war even though intelligence from Curveball had not changed in two years.

At the Central Intelligence Agency, officials embraced Curveball's account even though they could not confirm it or interview him until a year after the invasion. They ignored multiple warnings about his reliability before the war, punished in-house critics who provided proof that he had lied and refused to admit error until May 2004, 14 months after the invasion.

One of those warnnings was from a CIA doctor who had actually met Curveball. His supervisors reaction:

"Keep in mind that this war is going to happen regardless of what Curve Ball said or didn't say and the Powers That Be probably aren't terribly interested in whether Curve Ball knows what he's talking about,"

And so the sad story continued.

After the CIA vouched for Curveball's accounts, Bush declared in his 2003 State of the Union speech that Iraq had "mobile biological weapons labs" designed to produce "germ warfare agents." Bush cited the mobile germ factories in at least four prewar speeches and statements, and other world leaders repeated the charge.

Powell also highlighted Curveball's "eyewitness" account when he warned the United Nations Security Council on the eve of war that Iraq's mobile labs could brew enough weapons-grade microbes "in a single month to kill thousands upon thousands of people."

The senior BND officer who supervised Curveball's case said he was aghast when he watched Powell misstate Curveball's claims as a justification for war.

"We were shocked," the official said. "Mein Gott! We had always told them it was not proven…. It was not hard intelligence."

And what was Curveballs reason for his fractured fairy tales?

Curveball's motive, CIA officials said, was not to start a war. He simply was seeking a German visa.

The whole story deserves to be read carefully by everyone.
