This paper addresses how fear and hate have had an impact on the ways in which people and nations behave. A study of World War II reveals to people the terrible consequences of fear and hate. After this long war ended, many hoped that the United Nations would put an end to warfare and the acts that had nourished hatred. Using the theme of "Fear and Hate vs. Hope and Cooperation" to study World War II, teachers can address World War II in a meaningful way with children of different ages, abilities, and interests. Suggestions are given for discussion questions, trade books, large and small group activities, and interviewing techniques. (EH)
