According to David Bruce MacDonald, Dadrian is a "towering figure in the field of Armenian genocide history". Taner Akcam writes that by employing Justin McCarthy's own method of calculating population figures and classifying individuals, Vahakn Dadrian has shown the ridiculousness of the claim that "the events of 1915 were in fact a civil war between the Armenians and Turks". German Swiss scholar Hans-Lukas Kieser writes that the documents related to fifteen Turkish ministers published by V. Dadrian show best the ministers' conception of their responsibility in the "abuses" committed against Ottoman Armenians.
