Unlike recent books on this question that have targeted the media or gone after the entire Bush administration, Five Biggest Lies takes a narrow focus: what Bush and his team said about Iraq, versus what they actually knew. Using testimony from whistleblowers' in high places, including the US Foreign Service and State Department, the authors demonstrate plainly that the warmongers had information contradicting their 'evidence of peril', 'imminent threat', 'urgent duty', 'alliance with terrorists' and, most recklessly of all, 'msuhroom cloud' talking points.'
