" Hitler's psychological artillery was composed primarily of the weapon of fear. He had, for example, a network of fifth columnists whose main job was to sow rumours and suspicions among the citizens of the countries against which he eventually planned to fight... [an example of such a rumour/slogan was:] "Why should France die for England?" Fear began to direct people's actions. Instead of facing the real threat of German invasion, instead of preparing for it, all of Europe shuddered at spy stories, discussed irrelevant problems, argued endlessly about scapegoats and minorities.
