U.S. President Harry S. Truman commented: "We must make the United Nations continue to work, and to be a going concern, to see that difficulties between nations may be settled just as we settle difficulties between States here in the United States. When Kansas and Colorado fall out over the waters in the Arkansas River, they don't go to war over it; they go to the Supreme Court of the United States, and the matter is settled in a just and honorable way. There is not a difficulty in the whole world that cannot be settled in exactly the same way in a world court". – President Truman's remarks in Omaha, Nebraska on June 5, 1948, at the dedication of the War Memorial. The cultural moment of the late 1940s was the peak of World Federalism among Americans.
