The Senate Intelligence Committee Report shreds the CIA's WMD intelligence: In a long-awaited report that goes to the heart of President Bush's rationale for going to war against Iraq, the committee said that prewar assessments of Saddam Hussein's supposed arsenal of chemical and biological weapons, and his desire to have nuclear weapons, were wildly off the mark. 'Today, we know these assessments were wrong, and as our inquiry will show, they were also unreasonable and largely unsupported by the available intelligence,' Senator Pat Roberts, the Kansas Republican who heads the panel, said at a briefing on the 511-page report. Mr. Roberts said the committee had found no evidence that intelligence analysts were subjected to overt political pressure to tailor their findings. And the senator praised the men and women in the intelligence field as 'true and dedicated professionals.' But he said the committee's investigation of many months had also concluded that intelligence analysis and conclusions about Iraq's weapons had been warped by 'a collective group-think' that caused ambiguous evidence to be elevated to the level of conclusive evidence. 'It is clear that this group-think also extended to our allies and to the United Nations and several other nations as well, all of whom did believe that Saddam Hussein had active w.m.d. programs,' Mr. Roberts said, using the abbreviation for weapons of mass destruction. 'This was a global intelligence failure.'
