The White House propaganda blitz was launched on September 7, 2002, at a Camp David press conference. British Prime Minister Tony Blair stood side by side with his co-conspirator, President George W. Bush. Together, they declared that evidence from a report published by the UN International Atomic Energy Agency (IAEA) showed that Iraq was "six months away" from building nuclear weapons.

"I don't know what more evidence we need," crowed Bush.

Actually, any evidence would help-there was no such IAEA report. But at the time, few mainstream American journalists questioned the leaders' outright lies. Instead, the following day, "evidence" popped up in the Sunday New York Times under the twin byline of Michael Gordon and Judith Miller. "More than a decade after Saddam Hussein agreed to give up weapons of mass destruction," they stated with authority, "Iraq has stepped up its quest for nuclear weapons and has embarked on a worldwide hunt for materials to make an atomic bomb, Bush administration officials said today."

In a revealing example of how the story amplified administration spin, the authors included the phrase soon to be repeated by President Bush and all his top officials: "The first sign of a 'smoking gun,' [administration officials] argue, may be a mushroom cloud."

This was the classic disinformation two-step: the White House leaks a lie to The Times, the newspaper publishes it as a startling expose, and then the White House conveniently masquerades behind the credibility of The Times.

"What mattered," wrote MacArthur, "was the unencumbered rollout of a commercial for war."

After a year of bogus scoops from Miller, the paper gave itself a bit of cover. Not corrections-just cover. On September 28, 2003, Times reporter Douglas Jehl surprisingly kicked the legs out from under Miller's sources. In his story headlined AGENCY BELITTLES INFORMATION GIVEN BY IRAQ DEFECTORS, Jehl revealed: An internal assessment by the Defense Intelligence Agency has concluded that most of the information provided by Iraqi defectors who were made available by the Iraqi National Congress was of little or no value, according to federal officials briefed on the arrangement. In addition, several Iraqi defectors introduced to American intelligence agents by the exile organization and its leader, Ahmed Chalabi, invented or exaggerated their credentials as people with direct knowledge of the Iraqi government and its suspected unconventional weapons program, the officials said.
