At the dawn of the twentieth century, the United States was one of the world's richest, most populous, most technologically advanced nations. It was also a nation divided along numerous fault lines, with conflicting aspirations and concerns pulling it in different directions.

Many preferred to avoid being drawn into what seemed an ever more competitive, conflictual, and militarized international environment.
