"The Lost Fruits of Waterloo" by John Spencer Bassett is a historical account written in the early 20th century. The work explores the consequences of the Napoleonic Wars and the subsequent attempts to establish lasting peace in Europe, particularly reflecting on the failures to unite nations effectively after the defeat of Napoleon. Bassett emphasizes the need for a structured cooperative approach among nations to prevent future conflicts. The opening of the book begins with a preface where Bassett reveals his motivation for writing, inspired by President Wilson's advocacy for a league of nations to ensure permanent peace after World War I. He reflects on the historical context of the Napoleonic Wars, suggesting that the peace achieved post-Waterloo was superficial and temporary, as the fundamental issues of conflict remained unaddressed. Bassett outlines the evolving landscape of international relations, hinting at the recurring historical ideologies that spur conflict and the critical importance of creating a sustainable system of cooperation among nations.
