During the earlier years of the League we were fortunate in having many statesmen of outstanding ability who were convinced supporters of international cooperation under the League Covenant. … It is enough to say that under the leadership of those great men the first ten years of the League of Nations was a period of almost unbroken prosperity. The League moved from strength to strength. It established its organization and its Secretariat — a very remarkable achievement which has worked extremely well. Then, too, came the Permanent Court of International Justice, which has also been a very marked success and which, I trust, will establish ultimately the rule of law in all international affairs.
