The truck-lab diagram shown to the Security Council on 5 February 2003

A State Department slide from Colin Powell's 5 February 2003 presentation to the UN Security Council renders truck-mounted plants for making biological agents. The claim behind it rested mainly on one defector known as Curveball.

What the slide shows

The image is a computer rendering, not a photograph. Truck trailers are drawn in cutaway, with each piece of equipment labeled as if it had been inspected. The only words on the slide are its title and those labels:

Mobile Production Facilities For Biological Agents

Active Material Tanks

Spray Dryers

Filling Machine

Fermentation

Control Panel

Who presented it

The slide belongs to the U.S. Department of State: it was part of Secretary of State Colin Powell's remarks to the UN Security Council on 5 February 2003, about six weeks before the invasion of Iraq. The archive took it from Wikimedia Commons on 27 September 2026 and records it as a public-domain U.S. government work.

What it left out

A rendering carries a particular kind of authority. Clean lines and part names read as knowledge, and nothing on the slide tells the viewer how much was seen and how much was inferred. According to the archive record, the claim rested mainly on a single Iraqi defector, code-named Curveball, whose reliability had already been doubted inside U.S. and German intelligence. Those doubts were not on the screen. The slide presented the labs as a settled fact.

The audience in the room was the Security Council, but the audience that mattered under the Constitution was at home. Congress authorizes force, and citizens hold Congress to account; both depend on knowing how firm the evidence is. A drawing that drops the caveats takes that judgment away from them while appearing to inform it. That is the wrong here, and it is the government's, whatever one thinks of the war.

The case study Caveats in the vault, certainty at the podium places this slide in the wider case for war, and also covers Johnson's Gulf of Tonkin address. The Nayirah case study, Kuwait's money, an unsworn witness, names it as the closest American parallel in the archive.
