“CBS News’ 60 Minutes exposure last night of the Iraqi agent known as CURVEBALL has put a major aspect of the Bush administration’s case for war against Iraq back under the spotlight. Rafid Ahmed Alwan’s charges that Iraq possessed stockpiles of biological weapons and the mobile plants to produce them formed a critical part of the U.S. justification for the invasion in Spring 2003. Secretary of State Colin L. Powell’s celebrated and globally televised briefing to the United Nations Security Council on February 5, 2003, relied on CURVEBALL as the main source of intelligence on the biological issue. Today the National Security Archive posts the available public record on CURVEBALL’s information derived from declassified sources and former officials’ accounts.”
