“The United States never joined the League. Most historians hold that the League operated much less effectively without U.S. participation than it would have otherwise. However, even while rejecting membership, the Republican Presidents of the period, and their foreign policy architects, agreed with many of its goals. To the extent that Congress allowed, the Harding, Coolidge, and Hoover administrations associated the United States with League efforts on several issues. Constant suspicion in Congress, however, that steady U.S. cooperation with the League would lead to de facto membership prevented a close relationship between Washington and Geneva. Additionally, growing disillusionment with the Treaty of Versailles diminished support for the League in the United States and the international community. Wilson’s insistence that the Covenant be linked to the Treaty was a blunder; over time, the Treaty was discredited as unenforceable, short-sighted, or too extreme in its provisions, and the League’s failure either to enforce or revise it only reinforced U.S. congressional opposition to working with the League under any circumstances. However, the coming of World War II once again demonstrated the need for an effective international organization to mediate disputes, and the United States public and the Roosevelt administration supported and became founding members of the new United Nations.”
