Experience has shown that the mass-armies of "democratic” states fight with greater zeal when they are animated by hatred and supported by a hate-crazed populace that fancies it is fighting a holy war. Lies have therefore become military equipment, a kind of mental logistics; but it is the essence of such propaganda that its spuriousness is known only to the persons who manufacture it. The model of such operations is the famous lie-factory managed by Lord Bryce during the First World War, in which a corps of expert technicians forged photographs, while expert liars, including Arnold Toynbee, concocted stories, of "atrocities,” to inspire the emotionally overwrought British with a fanatical hatred of the incredibly bestial Germans and with a noble Christian ardor to kill them.
