Historian Adam Hochschild:

Lessons for the Antiwar Movement from the Pacifists of World War I
As the Obama administration continues to engage in military operations abroad, we turn now to the making—and sustaining—of war from a historical perspective. How do politicians galvanize populations to support wars? Why do people continue fighting in unpopular conflicts even after nationalist fervor has waned? In his new book, the historian Adam Hochschild examines these questions and many others through the prism of one of the world’s bloodiest conflicts, World War I. The book is called To End All Wars: A Story of Loyalty and Rebellion, 1914-1918.
