THE HOLOCAUST REENACTED THE FIRST WORLD WAR
Richard Rhodes

“The Great War set the stage for the Holocaust. The foul trenches (‘the long grave already dug,’ the English poet John Masefield called them), the no man’s lands of barbed wire, the piles of rotting corpses, the muddy, denuded landscape--prefigured the killing pits and the death camps of the Third Reich."
