You know, we don't really mind if you make it up

I'm sure we'll beat the truth out of these guys eventually.

Despite vigorous efforts, the U.S. government has been unsuccessful so far in finding key senior Iraqi scientists to support its prewar claims that former president Saddam Hussein was pursuing an aggressive program to develop nuclear, biological and chemical weapons, according to senior administration officials and members of Congress who have been briefed recently on the subject.

The sources said four senior scientists and more than a dozen at lower levels who worked for the Iraqi government have been interviewed by U.S. officials under the direction of the CIA. Some scientists have been arrested and held for months, others have made deals in return for information and at least one has agreed to be interviewed outside Iraq.

No matter the circumstances, all of the scientists interviewed have denied that Hussein had reconstituted his nuclear weapons program or developed and hidden chemical or biological weapons since United Nations inspectors left in 1998. Several key Iraqi officials questioned the significance of evidence cited by the Bush administration to suggest that Hussein was stepping up efforts to develop new weapons of mass destruction programs.
