Background: John Richard Pilger (; born 9 October 1939) is an Australian journalist and documentary film maker mainly based in the United Kingdom since 1962. Pilger has been a strong critic of American, Australian and British foreign policy, which he considers to be driven by an imperialist agenda. Pilger has also criticised his native country's treatment of Indigenous Australians. His career as a documentary film maker began with The Quiet Mutiny (1970), made during one of his visits to Vietnam, and has continued with over fifty documentaries since then.
Context: William Shawcross wrote in his book The Quality of Mercy: Cambodia, Holocaust and Modern Conscience (1984) about Pilger's series of articles about Cambodia in the Daily Mirror during August 1979: "A rather interesting quality of the articles was their concentration on Nazism and the holocaust. Pilger called Pol Pot 'an Asian Hitler' -- and said he was even worse than Hitler . . . Again and again Pilger compared the Khmer Rouge to the Nazis. Their Marxist-Leninist ideology was not even mentioned in the Mirror, except to say they were inspired by the Red Guards. Their intellectual origins were described as 'anarchist' rather than Communist". Ben Kiernan, in his review of Shawcross's book, notes that Pilger did compare Pol Pot's Khmer Rouge to Stalin's terror, as well as to Mao's Red Guards. Kiernan notes instances where other writers' comparisons of Pol Pot to Hitler or the Vietnamese to the Nazis are either accepted by Shawcross in his account, or not mentioned. Shawcross wrote in The Quality of Mercy that "Pilger's reports underwrote almost everything that refugees along the Thai border had been saying about the cruelty of Khmer Rouge rule since 1975, and that had already appeared in the books by the Readers Digest and Francois Ponchaud. Nonetheless, the reaction to the stories in Britain was as if they were something quite new." Oliver Kamm asserted in 2006: "Pilger's documentaries are full of falsehoods. They operate by misdirection, simultaneously denouncing one form of injustice while ignoring or denying others". In Heroes, Pilger disputes Francois Ponchaud and Shawcross's account of Vietnamesse atrocities during the Vietnamese invasion and near famine as being "unsubstantiated". Ponchard had interviewed members of anti-communist groups living in the Thai refugee border camps. According to Pilger, "At the very least the effect of Shawcross's 'expose'" of Cambodian's treatment at the hands of the Vietnamese "was to blur the difference between Cambodia under Pol Pot and Cambodia liberated by the Vietnamese: in truth. a difference of night and day". In his book, Shawcross himself doubted that anyone had died of starvation.
