We have still a very long road to travel before we arrive at the establishment of an international authority, but it is not very difficult to foresee the steps by which this result will be gradually reached. There is likely to be a continual increase in the practice of submitting disputes to arbitration, and in the realization that the supposed conflicts of interest between different states are mainly illusory. Even where there is a real conflict of interest, it must in time become obvious that neither of the states concerned would suffer as much by giving way as by fighting. With the progress of inventions, war, when it does occur, is bound to become increasingly destructive. The civilized races of the world are faced with the alternative of cooperation or mutual destruction. The present war is making this alternative daily more evident. And it is difficult to believe that, when the enmities which it has generated have had time to cool, civilized men will deliberately choose to destroy civilization, rather than acquiesce in the abolition of war. The matters in which the interests of nations are supposed to clash are mainly three: tariffs, which are a delusion; the exploitation of inferior races, which is a crime; pride of power and dominion, which is a schoolboy folly. The economic argument against tariffs is familiar, and I shall not repeat it. The only reason why it fails to carry conviction is the enmity between nations. Nobody proposes to set up a tariff between England and Scotland, or between Lancashire and Yorkshire. Yet the arguments by which tariffs between nations are supported might be used just as well to defend tariffs between counties. Universal free trade would indubitably be of economic benefit to mankind, and would be adopted to-morrow if it were not for the hatred and suspicion which nations feel one toward another. From the point of view of preserving the peace of the world, free trade between the different civilized states is not so important as the open door in their dependencies. The desire for exclusive markets is one of the most potent causes of war. Exploiting what are called "inferior races" has become one of the main objects of European statecraft. It is not only, or primarily, trade that is desired, but opportunities for investment; finance is more concerned in the matter than industry. Rival diplomatists are very often the servants, conscious or unconscious, of rival groups of financiers. The financiers, though themselves of no particular nation, understand the art of appealing to national prejudice, and of inducing the taxpayer to incur expenditure of which they reap the benefit. The evils which they produce at home, and the devastation that they spread among the races whom they exploit, are part of the price which the world has to pay for its acquiescence in the capitalist regime.
