　　War Made Easy reaches into the Orwellian memory hole to expose a 50-year pattern of government deception and media spin that has dragged the United States into one war after another from Vietnam to Iraq. Narrated by actor and activist Sean Penn, the film exhumes remarkable archival footage of official distortion and exaggeration from LBJ to George W. Bush, revealing in stunning detail how the American news media have uncritically disseminated the pro-war messages of successive presidential administrations.
