American elites still pursued the broader project of making such treaties in the aftermath of this bitter experience. The Republican secretary of state and later New York senator Elihu Root was a fanatic for arbitration in order to keep the United States out of European wars.

U.S. interest in international law exploded, with professional associations formed and new journals founded.
