The world has become so closely connected through modern means of communication that any war might result in a world war. The prevalent political tendencies are in the direction of combination and resultant consolidation. The question soon arises, Shall combination and regulation go beyond national limits? The old-fashioned ideas of national limits do not seem to be adapted to present conditions. Commercially such limits are impracticable and appear to be so in other ways.[6] The Constitution of the United States has 18 amendments. This demographic law of interdependence of nations necessarily results in combination, which eventually may lead to international solidarity. Whether we will or no, this demographic law of interdependence of nations can not be escaped. Just as the States of the Union are now closer together than their counties were many years ago, through the enormous development of physical means of communication, so governments are now brought more closely in contact than were the States at the time of the formation of the Union. This demographic law of increasing interdependence when carefully examined appears to be almost as necessary as the law of gravity. It has been at work ever since history began and, though little noticed perhaps, it has been manifesting itself more and more as history advanced. The individual is subordinate to the community and must yield some of his sovereignty to it, the community in turn must yield to the county, the county to the State, the State to the Nation, and finally the Nation to the world. This last step is the one now pending in Europe, and eventually, if not presently, may result in international solidarity, which will practically put an end to political wars just as the Westphalian peace did with religious wars. INTERNATIONAL ORGANIZATIONS AND DEMOGRAPHIC LAW OF INTERDEPENDENCE OF STATES. The tendency toward this demographic law of interdependence of States is shown by the large number of international organizations such as congresses or conferences which are held from time to time in different countries of the world. From the Conference of Vienna (1815) to the present time there have been some two hundred or more international congresses, the majority of which had to do with regulation of economic and sociologic affairs. Thus manufacturers, merchants, and capitalists of different countries have met and made agreements to control and regulate production and distribution of merchandise. There is also the Universal Postal Union, which is an illustration of international control or government. Objections are sometimes made against international government, which were made years ago against the International Postal Union. It now has a constitution obeyed by all nations. Refusal to obey would deprive a country of the benefits of the union. As a matter of fact, no country has done this. POWER OF INTERNATIONAL ORGANIZATIONS.
