In addition to coming up with his name and his aim (to emigrate to Germany), 60 Minutes will report this Sunday:

Although German intelligence officials warned the CIA that Curveball’s claims of mobile bioweapons labs were unreliable, and U.N. inspectors determined before the war began in 2003 that parts of his story were false, the Bush administration continued to promote the existence of such mobile labs for months after the invasion, until it was widely accepted that they could not be found.

Not much new here, but it makes clear that the mobile labs claims were already fairly well debunked in advanc of the war. This is what Colin Powell testified to the UN security council in February:

One of the most worrisome things that emerges from the thick intelligence file we have on Iraq’s biological weapons is the existence of mobile production facilities used to make biological agents.

Let me take you inside that intelligence file and share with you what we know from eye witness accounts. We have firsthand descriptions of biological weapons factories on wheels and on rails.

The trucks and train cars are easily moved and are designed to evade detection by inspectors. In a matter of months, they can produce a quantity of biological poison equal to the entire amount that Iraq claimed to have produced in the years prior to the Gulf War.

Although Iraq’s mobile production program began in the mid-1990s, U.N. inspectors at the time only had vague hints of such programs. Confirmation came later, in the year 2000.

The source was an eye witness, an Iraqi chemical engineer who supervised one of these facilities. He actually was present during biological agent production runs. He was also at the site when an accident occurred in 1998. Twelve technicians died from exposure to biological agents.

He reported that when UNSCOM was in country and inspecting, the biological weapons agent production always began on Thursdays at midnight because Iraq thought UNSCOM would not inspect on the Muslim Holy Day, Thursday night through Friday. He added that this was important because the units could not be broken down in the middle of a production run, which had to be completed by Friday evening before the inspectors might arrive again.

This defector is currently hiding in another country with the certain knowledge that Saddam Hussein will kill him if he finds him. His eye-witness account of these mobile production facilities has been corroborated by other sources.

A second source, an Iraqi civil engineer in a position to know the details of the program, confirmed the existence of transportable facilities moving on trailers.

A third source, also in a position to know, reported in summer 2002 that Iraq had manufactured mobile production systems mounted on road trailer units and on rail cars.

Finally, a fourth source, an Iraqi major, who defected, confirmed that Iraq has mobile biological research laboratories, in addition to the production facilities I mentioned earlier.

We have diagrammed what our sources reported about these mobile facilities. Here you see both truck and rail car-mounted mobile factories. The description our sources gave us of the technical features required by such facilities are highly detailed and extremely accurate. As these drawings based on their description show, we know what the fermenters look like, we know what the tanks, pumps, compressors and other parts look like. We know how they fit together. We know how they work. And we know a great deal about the platforms on which they are mounted.

As shown in this diagram, these factories can be concealed easily, either by moving ordinary-looking trucks and rail cars along Iraq’s thousands of miles of highway or track, or by parking them in a garage or warehouse or somewhere in Iraq’s extensive system of underground tunnels and bunkers.

We know that Iraq has at lest seven of these mobile biological agent factories. The truck-mounted ones have at least two or three trucks each. That means that the mobile production facilities are very few, perhaps 18 trucks that we know of — there may be more — but perhaps 18 that we know of. Just imagine trying to find 18 trucks among the thousands and thousands of trucks that travel the roads of Iraq every single day.

It took the inspectors four years to find out that Iraq was making biological agents. How long do you think it will take the inspectors to find even one of these 18 trucks without Iraq coming forward, as they are supposed to, with the information about these kinds of capabilities?

Ladies and gentlemen, these are sophisticated facilities. For example, they can produce anthrax and botulism toxin. In fact, they can produce enough dry biological agent in a single month to kill thousands upon thousands of people. And dry agent of this type is the most lethal form for human beings.

By 1998, U.N. experts agreed that the Iraqis had perfected drying techniques for their biological weapons programs. Now, Iraq has incorporated this drying expertise into these mobile production facilities.

So Powell testified that the primary source was Curveball, that three others confirmed the story, and that US intelligence ‘knew’ they existed. He forgot to mention that German intelligence didn’t belive Curveball was on the level. And while UN inspectors poked visible holes in Curveball’s stories, before the war, the White House kept claiming these labs existed.

Just like it kept referring to the uranium yellowcake from Nigeria that Joe Wilson helped debunk. Just like it kept claiming ties between Al Qaida and Saddam, also discredited.

As I said, 60 Minutes will be adding a few formerly known details. The main question remaining is not whether the Bush administration twisted the intel to support its desire to invade, but did they present any unskewed evidence at all?
