Hans Martin Blix (Swedish: [hɑːns ˈblɪks]; born 28 June 1928) is a Swedish diplomat and politician for the Liberal People's Party. He was Swedish Minister for Foreign Affairs (1978–1979) and later became the head of the International Atomic Energy Agency. Blix was the first Western representative to inspect the consequences of the Chernobyl disaster in the Soviet Union on-site and led the agency's response to them. Blix was also the head of the United Nations Monitoring, Verification and Inspection Commission from March 2000 to June 2003, when he was succeeded by Dimitris Perrikos. In 2002, the commission began searching Iraq for weapons of mass destruction, ultimately finding none. On 17 March 2003, U.S. President George W. Bush delivered an address from the White House announcing that within 48 hours, the United States would invade Iraq unless Saddam Hussein would leave. Bush then ordered all of the weapons inspectors, including Blix's team, to leave Iraq so that America and its allies could invade Iraq on 20 March. In February 2010, Blix became head of the United Arab Emirates' advisory board for its nuclear power program. He is the former president of the World Federation of United Nations Associations.
