After playing a major role in winning the Great War, Americans were disillusioned by the peace process and the realization that war had not been abolished forever. At the moment that America had finally become a global power, Garrett Peck points out, it retreated into isolationism. How did President Woodrow Wilson's idealism go sour so quickly? Noting the turbulent domestic struggles with the Red Scare, race riots, women's suffrage, and Prohibition, Peck also theorizes why the first global conflict remains a forgotten war in America.
