"... three categories of atrocities: what we called there "constructive","benign" and "nefarious" bloodbaths. "Constructive bloodbaths" are those that serve the interests of U.S. power; "benign bloodbaths" are largely irrelevant to these concerns; and "nefarious bloodbaths" are those that can be charged to account of official enemies and ere thus useful for mobilizing the public."
