D. Blatman presents an ongoing research on the end of World War II and of Shoah and Nazi genocide, arguing that differences between prisoners for different reasons (Jews and others) were somehow fading away in those last months, while there was a growing generalized violence, which he illustrates presenting specific cases of massacre and profiles of persecutors. M. de Bernart introduces the theme in general, linking Holocaust studies to the work and duty of memory as expressed in institutional settings; and, specifically, examines the implications of Blatman's attention to the last phases of war in a cultual-scientific context which generally links all perspectives of prevention to paying attention to early warning or middle phases.
