Just as a state's police swear to prevent and punish murder, so the signers of the Genocide Convention [in 1948] swore to police a brave new world order. The rhetoric of moral utopia is a peculiar response to genocide. But those were heady days, just after the trials at Nuremberg, when the full scale of the Nazi extermination of Jews all over Europe had been recognized as a fact of which nobody could any longer claim ignorance. The authors and signers of the Genocide Convention knew perfectly well that they had not fought World War II to stop the Holocaust but rather--and often, as in the case of the United States, reluctantly--to contain fascist aggression. What made those victorious powers, which dominated the UN then even more than they do now, imagine that they would act differently in the future?
