The prompt adoption of the Charter of the United Nations by the United States stands in bold relief against the failure to ratify, the Covenant of the League of Nations twenty-five years ago. The causes responsible for the success of the Charter and the failure of the Covenant are probably diverse in character and varying in importance. The indorsement of the Charter by a virtually unanimous vote in the Senate was probably due in no small measure to the decision of the Roosevelt Administration to place the issue of American participation in an international security organization, almost from the very beginning, on a non-partisan basis. The issue, however, was not one of joining an international organization of the Woodrow Wilson type. The vote in the Senate, accordingly, does not necessarily represent a belated conversion to the idealism of Wilson. It would seem, on the contrary, that the Roosevelt Administration, drawing on the rich experience of international cöoperation during the interwar period, and more particularly during World War II, had taken care to keep from the Charter all the important matters to which the majority of the Senate, in voting on the Covenant with the Lodge Reservations on March 19, 1920, had taken exception. It may be that this policy was merely part of an over-all strategy aiming at bringing the United States into some sort of international security organization rather than running the risk of a repetition of the 1919/1920 drama. It may be, on the other hand, that the Roosevelt Administration, together with the other sponsoring governments, had become genuinely convinced that the League Covenant represented a type of international organization which, under the prevailing circumstances, was unattainable or undesirable or unworkable in practice.
