In the '' Journal of Genocide Research '' , David Stannard called Lewy one of the last of a disappearing breed : the extreme " uniqueness " advocate determined to assert — in the face of contrary and increasingly overwhelming fact and logic — that , of all the mass killings that have ever occurred in the history of the world , only the Holocaust , or more precisely the Shoah , rose to the level of true " genocide . " Lewy 's response included : Let me try to set the record straight : In none of my writings have I ever asserted the uniqueness or singularity of the Holocaust , and indeed I do not believe that the Holocaust is the only instance of mass killing that deserves to be classified as an act of genocide . With Yehuda Bauer I would call the Holocaust unprecedented but not unique , because the term unique suggests that something like the Holocaust can never happen again . In point of fact , later in the 20th century we witnessed the terrible genocides of Cambodia and Rwanda . I would welcome it if critics of my work would limit themselves to dealing with the substance of my positions rather than falsely impute to me ulterior motives . -- >
