Works of fiction often express things better than do works of history. At the outset of his remarkably perceptive novel, Home Fires: An Intimate Portrait of One Middle-Class Family in Postwar America, Donald Katz writes of his protagonist in 1945:

Hardly a surprising reaction to the horrors of war, and obviously it is a considerable leap from (Jewish) middle-class America to a devastated European continent after the destruction of the “Third Reich.” However, this pithy statement points to a major, perhaps the major, social and psychological turning point of our century.

The history of the twentieth century revolves around mass death. At its center lies the mass killing and mass murder carried out during the decade roughly from the late 1930s to the late 1940s - during which time more people were killed by their fellow human beings than ever before in the history of humankind. Against the terrible dimensions of the mass death of that decade, the hitherto unimaginable horrors of the First World War and its immediate aftermath appear as merely an antechamber to the house of horrors that arose two decades later.
