The US got it wrong" about Saddam Hussein and Iraq, the CIA analyst who interrogated the former dictator has said. John Nixon had numerous conversations with the deposed leader and now says that America was critically mistaken about their intervention Iraq. In particular, he claims, the CIA's view of Hussein's attitude to using chemical weapons was wrong. During the interrogations, Mr Nixon asked Hussein if he'd ever thought of engaging in a pre-emptive strike with WMDs against US troops based in Saudi Arabia. According to Mr Nixon ... the former dictator's reply was: "We never thought about using weapons of mass destruction. It was not discussed. Use chemical weapons against the world? Is there anyone with full faculties who would do this?" Mr Nixon admitted this was "not what we had expected to hear". The main reason the American and British governments used to justify the controversial invasion of Iraq was the supposed risk posed by the WMDs possessed by the country. Nearly 200,000 people have died in the conflicts that followed. Iraq is now widely regarded as a failed state, and still suffers from widespread violence. Thirteen years on, at least 5,000 American troops remain in the country. Mr Nixon also spoke out against Mr Bush, who was rude towards him and reportedly made inappropriate jokes about the missing WMDs. Mr Bush blamed the CIA for Iraq's failures, Mr Nixon said, adding that he "called its analysis 'guesswork' while hearing only what he wanted to hear".
