Robert Greenwald builds his case against the Iraq war entirely out of the government's own experts, assembling interviews with a former CIA director, a former U.S. ambassador to Saudi Arabia, career foreign service officers, and even President Bush's own Secretary of the Army, who question the administration's claims one by one. The film walks through the specific arguments made for invasion in the aftermath of September 11: aluminum tubes cited as evidence of a nuclear program, alleged links between Saddam Hussein and al-Qaeda, and the shifting rationale as earlier justifications failed to hold up. U.N. weapons inspectors describe what they actually found on the ground in Iraq, and intelligence officials describe how raw assessments got reshaped into public statements. Greenwald keeps the structure simple: administration claim, then the people whose job it was to know better explaining why it did not add up. Made while the war was still underway, it plays less like commentary and more like a cross-examination of the case for going in.
