PBS - Bill Moyers Journal: Buying the War orignially broadcast 25 April 2007.
"In the lead-up to the invasion of Iraq, the US government's claims about weapons of mass destruction and terrorist ties to Saddam Hussein went mostly unchallenged by the media. Four years after 'shock and awe,' how the government sold the war has been much examined, but a big question remains: how and why did the press buy it? Bill Moyers and his team piece together the reporting that shows how the media were complicit in shaping the 'public mind' toward the war, and ask what has happened to the press's role as skeptical 'watchdog' over government power. The program features the work of some journalists who didn't take the government's word at face value, including the team of reporters at Knight Ridder news service whose reporting turned up evidence at odds with the official view of reality. Buying the War includes interviews with Dan Rather, formerly of CBS; Tim Russert of Meet the Press; Bob Simon of 60 Minutes; Walter Isaacson, former president of CNN; and John Walcott, Jonathan Landay, and Warren Strobel of Knight Ridder newspapers, which was acquired by the McClatchy Co. in 2006."

• Book review:
  Illusions of Empire: Defining the New American Order
  by G. John Ikenberry, Foreign Affairs, March/April 2004

A good companion to this book is the documentary film: Why We Fight (2005), which includes interviews with Chalmers Johnson, and is inspired in part by President Eisenhower's Farewell Address in which he warned of (among other things): a new "permanent armaments industry of vast proportion," the military-industrial complex: "In the councils of government, we must guard against the acquisition of unwarranted influence, whether sought or unsought, by the military-industrial complex. The potential for the disastrous rise of misplaced power exists and will persist. We must never let the weight of this combination endanger our liberties or democratic processes. We should take nothing for granted. Only an alert and knowledgeable citizenry can compel the proper meshing of the huge industrial and military machinery of defense with our peaceful methods and goals, so that security and liberty may prosper together."
