Blix's statements about the Iraq WMD program came to contradict the claims of the Bush administration, and attracted a great deal of criticism from supporters of the invasion of Iraq. In an interview on BBC TV on 8 February 2004, Dr. Blix accused the U.S. and British governments of dramatising the threat of weapons of mass destruction in Iraq, in order to strengthen the case for the 2003 war against the regime of Saddam Hussein.
Newt Gingrich stated that approving Hans Blix as chief U.N. weapons inspector was a mistake made "even though he was clearly opposed to war and determined to buy time and find excuses for Saddam Hussein."
In an interview with London's Guardian newspaper, Hans Blix said, "I have my detractors in Washington. There are bastards who spread things around, of course, who planted nasty things in the media".
In 2004, Blix published a book, Disarming Iraq
, where he gives his account of the events and inspections before the coalition began its invasion.
Ultimately, no stockpiles of weapons of mass destruction were found, leading to accusations that the United States, and in particular its President George W. Bush had deliberately inflated intelligence or lied about Iraq's weapons in order to justify an invasion of the country.
