There is only one treaty in the world that, despite its limitations, binds nations together: the United Nations Charter. Representatives of fifty nations wrote and ratified the UN Charter in 1945, with others joining in the years that followed. The charter itself only sets the terms for the behaviour of nations. It does not and cannot create a new world. It depends on individual nations to either live by the charter or die without it.
