Endorsing "force to enforce peace" and praising the Monroe Doctrine as the mainstay of US international relationships, former President William Howard Taft lectured on "World Relationships and Their Effect on National and International Policies." The ex-president's concern, reported The Vassar Miscellany Weekly, was that the "most valuable thing we have," the United States government, was under threat from the natural cupidity of other nations. "Shall we permit this cupidity to be diverted towards our most precious possession? It is our duty to safeguard this possession and remove this constant temptation from them."

Defeated in 1912 in a bid for a second term, Taft and a group of eminent Americans founded the League to Enforce Peace in June of 1915.
