At the beginning of 1917 the air in America was vibrant with a strong, unfocused, and oddly unwarlike patriotism. The war in Europe was fascinating and it closely touched American interests, but it was a long way off and it seemed like a good war to stay out of. One of the country’s most popular songs was a little number that carried its message in its title—“I Didn’t Raise My Boy to Be a Soldier.” Woodrow Wilson had won re-election at least partly because “he kept us out of war.” He wrote stiff notes to the warring nations when American rights were trodden on, but he seemed unlikely to go any further than that. A musical show in 1916 drew a round of appreciative laughter with a skit showing a soldier marching along with a typewriter on his shoulder—the typewriter, it was explained, was “a Wilson machine gun.”
Then came Germany’s announcement of unrestricted submarine warfare, Wilson’s April message to Congress, the declaration of war—and America was in it. Now the powerful patriotic impulse had something to focus on, and there was an abrupt reorientation of the nation’s emotions.
