Bush made up some evidence
No, the CIA gave him faulty information. New York Times journalist has been researching how she got the WMD story wrong in her reporting back in the day and she writes in http://www.wsj.com/articles/th...
"There was no shortage of mistakes about Iraq, and I made my share of them. The newsworthy claims of some of my prewar WMD stories were wrong. But so is the enduring, pernicious accusation that the Bush administration fabricated WMD intelligence to take the country to war."
"My sources were the same counterterrorism, arms-control and Middle East analysts on whom I had relied for my stories about Osama bin Laden and al Qaeda’s growing threat to America—a series published eight months before 9/11 for which the Times staff, including me, won a Pulitzer."
"Another enduring misconception is that intelligence analysts were “pressured” into altering their estimates to suit the policy makers’ push to war. Although a few former officials complained about such pressure, several thorough, bipartisan inquiries found no evidence of it."
"The CIA repeatedly assured President Bush that Saddam Hussein still had WMD. Foreign intelligence agencies, even those whose nations opposed war, shared this view. And so did Congress. Over the previous 15 years, noted Stuart Cohen, the former vice chairman of the National Intelligence Council, none of the congressional committees routinely briefed on Iraqi WMD assessments expressed concern about bias or error."
"Hans Blix, the former chief of the international weapons inspectors, ... told the U.N. in January 2003 that despite America’s ultimatum, Saddam was still not complying fully with his U.N. pledges. In February, he said “many proscribed weapons and items,” including 1,000 tons of chemical agent, were still “not accounted for.”"
"Years would pass before U.S. soldiers found remnants of some 5,000 inoperable chemical munitions made before the first Gulf War that Saddam claimed to have destroyed. Not until 2014 would the U.S. learn that some of Iraq’s degraded sarin nerve agent was purer than Americans had expected and was sickening Iraqi and American soldiers who had stumbled upon it."
"A two-year study by Charles Duelfer, the former deputy chief of the U.N. inspectors who led America’s hunt for WMD in Iraq, concluded that Saddam Hussein was playing a double game, trying (on the one hand) to get sanctions lifted and inspectors out of Iraq and (on the other) to persuade Iran and other foes that he had retained WMD. Not even the Iraqi dictator himself knew for sure what his stockpiles contained, Mr. Duelfer argued. Often forgotten is Mr. Duelfer’s well-documented warning that Saddam intended to restore his WMD programs once sanctions were lifted."
