the Russian, French, Chinese and other governments to prevent military action against Iraq, and although Iraq almost certainly did not possess weapons of mass destruction, Saddam's desire to preserve ambiguity on the issue, together with his government's secrecy and previous attempts to deceive UN inspectors made it difficult for Iraq to convince the world that it had disarmed. For more information, see Iraqi Perspectives Project. The study also cites documents demonstrating that key evidence presented by Colin Powell to the United Nations in February 2003 had been severely misinterpreted by the U.S. government. Audiotapes played by Powell during his presentation, cited by Powell as evidence of Iraqi attempts to circumvent U.N. regulations on WMD, were reexamined in light of the new documents. According to the authors of the study: Ironically, it now appears that some of the actions resulting from Saddam's new policy of cooperation actually helped solidify the coalition's case for war. Over the years, Western intelligence services had obtained many internal Iraqi communications, among them a 1996 memorandum from the director of the Iraqi Intelligence Service directing all subordinates to "insure that there is no equipment, materials, research, studies, or books related to manufacturing of the prohibited weapons (chemical, biological, nuclear, and missiles) in your site." And when UN inspectors went to these research and storage locations, they inevitably discovered lingering evidence of WMD-related programs. In 2002, therefore, when the United States intercepted a message between two Iraqi Republican Guard Corps commanders discussing the removal of the words "nerve agents" from "the wireless instructions," or learned of instructions to "search the area surrounding the headquarters camp and [the unit] for any chemical agents, make sure the area is free of chemical containers, and write a report on it," U.S. analysts viewed this information through the prism of a decade of prior deceit. They had no way of knowing that this time the information reflected the regime's attempt to ensure it was in compliance with UN resolutions. What was meant to prevent suspicion thus ended up heightening it. Website closure In November 2006, the documents were removed from the Internet by the Office of the Director of National Intelligence. The U.S. government had already received warnings about the site's content from the International Atomic Energy Agency, who was specifically concerned about sensitive documents about the pre-1991 Iraqi nuclear program, but the documents were not removed until the New York
