"And it is ridiculous to blame the Americans for atrocities committed by one of the worst thugs in the latter half of the 20th centuiry - Pol Pot."
In fact, the US had been secretly funding Pol Pot in exile since January 1980. The extent of this support - $85m from 1980 to 1986 - was revealed in correspondence to a member of the Senate Foreign Relations Committee. On the Thai border with Cambodia, the CIA and other intelligence agencies set up the Kampuchea Emergency Group, which ensured that humanitarian aid went to Khmer Rouge enclaves in the refugee camps and across the border. Two American aid workers, Linda Mason and Roger Brown, later wrote: "The US government insisted that the Khmer Rouge be fed . . . the US preferred that the Khmer Rouge operation benefit from the credibility of an internationally known relief operation." Under American pressure, the World Food Programme handed over $12m in food to the Thai army to pass on to the Khmer Rouge; "20,000 to 40,000 Pol Pot guerillas benefited," wrote Richard Holbrooke, the then US assistant secretary of state.
...The Cambodian training became an exclusively British operation after the "Irangate" arms-for-hostages scandal broke in Washington in 1986.

It was one of those classic Thatcher-Reagan arrangements.
...Khieu Samphan, Pol Pot's prime minister during the years of genocide, took the salute of UN troops with their commander, the Australian general John Sanderson, at his side. Eric Falt, the UN spokesman in Cambodia, told me: "The peace process was aimed at allowing [the Khmer Rouge] to gain respectability."
