President Harry S. Truman signs the United Nations Charter, and the United States becomes the first nation to complete the ratification process and join the new international organization. Although hopes were high at the time that the United Nations would serve as an arbiter of international disputes, the organization also served as the scene for some memorable Cold War clashes.
President Truman took a step that many Americans hoped would mean continued peace in the post-World War II world. The president signed the United Nations Charter, thus completing American ratification of the document. Secretary of State James F. Byrnes also signed. In so doing, the United States became the first nation to complete the ratification process. The charter would come into full force when China, Russia, Great Britain, France, and a majority of the other nations that had constructed the document also completed ratification.
