"There was, to be sure, a great deal to regret about the Cold War: the running of risks with everyone's future; the resources expended for useless armaments; the environmental and health consequences of massive military-industrial complexes; the repression that blighted the lives of entire generations; the loss of life that all too often accompanied it. No tyrant anywhere had ever executed a fifth of his own people, and yet the Khmer Rouge leader Pol Pot did precisely this in the aftermath of the Vietnam War. The future will surely remember that atrocity when it has forgotten much else about the Cold War, and yet hardly anyone outside of Cambodia noticed at the time. There was no trial for crimes against humanity: Pol Pot died in a simple shack along the Thai border in 1998, and was unceremoniously cremated on a heap of junk and old tires. At least there was no mausoleum."
