Germany's former foreign minister Joschka Fischer has accused the former head of the CIA George Tenet of making implausible claims about the handling of the Curveball case by the US.
On Wednesday Tenet, the director of central intelligence between 1997 and 2004, issued a statement on his website saying he discovered "too damn late" that Curveball – the Iraqi defector who became a key source for the CIA and the German secret service (BND) – might be a fabricator.
Reprinting an extract from his autobiography, Tenet claimed he only found out in 2005, two years after the Iraq invasion, that the BND had doubts about Curveball's claims to have witnessed first-hand Saddam Hussein's bio-weapons programme.
Asked by the Guardian whether Tenet's claims were plausible, Fischer said: "No. I don't think so."
Fischer said the BND realised some time before the war that Curveball was not a watertight source, and passed on his testimony to the CIA with warnings attached.
"Our position was always: [Curveball] might be right, but he might not be right. He could be a liar but he could be telling the truth," said Fischer at a press conference in Berlin to promote his memoir about the Iraq war.
Fischer said Germany was put in a "very difficult position" when the CIA asked whether they could "have" Curveball, or at least use his evidence to justify a war in Iraq. Germany's official position was that it would not join the coalition of the willing. Fischer himself famously told Donald Rumsfeld in February 2003 that he was "not convinced" about the case for war.
