As Friedländer notes in The Years of Extermination, Hitler lost the war against the Allied forces but not the one he unleashed against the Jews.

Conversely, in the face of imminent destruction, the victims accumulated testimonies. Are there such things as languages of life and languages of death? Dialogue between a historian and his translator.
