カール・フォン・クラウゼヴィッツ
The strategy of demonization of the enemy unavoidably leads to a vicious cycle of atrocities, which was elaborated by many authors including Carl von Clausewitz. Demonization of the enemy makes diplomatic solution impossible and inevitably leads into the war or worsening of relations. Depicting the enemy as particularly evil inspires feelings that make killings more easy.
