1 Recent literature on Americans during the neutrality phase of World War I include Keene, Jennifer D., “Americans Respond: Perspectives on the Global War, 1914–1917,” Geschichte und Gesellschaft 40:2 (2014): 266–86; Irwin, Julia F., Making the World Safe: The American Red Cross and a Nation's Humanitarian Awakening (New York: Oxford University Press, 2013). May's, Henry F. study remains particularly relevant: The End of American Innocence: A Study of the First Years of Our Own Time, 1912–1917 (New York: Alfred A. Knopf, 1959). For a recent overview of groups of Americans in the war zone, also see Rose, Kenneth D., The Great War and Americans in Europe, 1914–1917 (New York: Routledge, 2017).

4 Consider, for example, Irwin, Julia, “Taming Total War: Great War-Era American Humanitarianism and Its Legacies,” Diplomatic History 38:4 (2014): 763–75. Irwin proposes “a reperiodization of U.S. involvement in the war” since American “participation in the conflict entailed more than a three-year window of U.S. military intervention and postwar peace negotiations” (765).

32 This limitation was particularly striking in the case of a debate at Harvard University about a proposed monument dedicated to the university's war volunteers. Should the monument be dedicated to Harvard men who had fought on both sides in the war, or only to those who had fought for the Allies? One father whose son died as a pilot in France in 1916 argued that a monument honoring all volunteers would be a “monument of zero” but he did not call for intervention.
