The trauma of the First World War gives Europe no appetite for any further conflicts, but within subsequent two decades the world would return to rearmament and militarism. The Paris Peace Conference introduced the concept of self-determination, leading to the establishment of Czechoslovakia, Poland and Yugoslavia from the former Central Powers. The League of Nations is established to assist in resolving international disputes in an open environment, but fails to receive strong support and is eventually provent impotent in preventing Italy's conquest of Ethiopia. Despite a public push for disarmament, prompted by All Quiet on the Western Front and other reminders of the First World War, few countries make any serious moves. French and British demands for heavy war reparations, lead to Germany's economic ruin, but this and other unforseen consequences of the Treaty of Versailles would result in the emergence of Adolf Hitler. As Germany begins to absorb its neighbours, the rest of europe mobilises, and the moral utility of pacifism is questioned. The introductory scene shows Armistice Day. Interviewees include Lord Soper.
