From Joschka Fischer:
An Oral History of the Bush White House: Politics & Power: vanityfair.com: Joschka Fischer, German foreign minister and vice-chancellor: I was astonished that the Americans used Curveball, really astonished. This was our stuff. But they presented it not in the way we knew it. They presented it as a fact, and not as the way an intelligence assessment is—could be, but could also be a big lie. We don’t know.
