The international authority ought to possess an army and navy, and these ought to be the only army and navy in existence. The only legitimate use of force is to diminish the total amount of force exercised in the world. So long as men are free to indulge their predatory instincts, some men or groups of men will take advantage of this freedom for oppression and robbery. Just as the police are necessary to prevent the use of force by private citizens, so an international police will be necessary to prevent the lawless use of force by separate states.
But I think it is reasonable to hope that if ever an international government, possessed of the only army and navy in the world, came into existence, the need of force to enact obedience to its decisions would be very temporary. In a short time the benefits resulting from the substitution of law for anarchy would become so obvious that the international government would acquire an unquestioned authority, and no state would dream of rebelling against its decisions. As soon as this stage had been reached, the international army and navy would become unnecessary.
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 coöperation 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 régime.
But neither tariffs nor financiers would be able to cause serious trouble, if it were not for the sentiment of national pride. National pride might be on the whole beneficent, if it took the direction of emulation in the things that are important to civilization. If we prided ourselves upon our poets, our men of science, or the justice and humanity of our social system, we might find in national pride a stimulus to useful endeavors. But such matters play a very small part. National pride, as it exists now, is almost exclusively concerned with power and dominion, with the extent of territory that a nation owns, and with its capacity for enforcing its will against the opposition of other nations. In this it is reinforced by group morality. To nine citizens out of ten it seems self-evident, whenever the will of their own nation clashes with that of another, that their own nation must be in the right. Even if it were not in the right on the particular issue, yet it stands in general for so much nobler ideals than those represented by the other nation to the dispute, that any increase in its power is bound to be for the good of mankind. Since all nations equally believe this of themselves, all are equally ready to insist upon the victory of their own side in any dispute in which they believe that they have a good hope of victory. While this temper persists, the hope of international coöperation must remain dim.
If men could divest themselves of the sentiment of rivalry and hostility between different nations, they would perceive that the matters in which the interests of different nations coincide immeasurably outweigh those in which they clash; they would perceive, to begin with, that trade is not to be compared to warfare; that the man who sells you goods is not doing you an injury. No one considers that the butcher and the baker are his enemies because they drain him of money. Yet as soon as goods come from a foreign country, we are asked to believe that we suffer a terrible injury in purchasing them. No one remembers that it is by means of goods exported that we purchase them. But in the country to which we export, it is the goods we send which are thought dangerous, and the goods we buy are forgotten. The whole conception of trade, which has been forced upon us by manufacturers who dreaded foreign competition, by trusts which desired to secure monopolies, and by economists poisoned by the virus of nationalism, is totally and absolutely false. Trade results simply from division of labor. A man cannot himself make all the goods of which he has need, and therefore he must exchange his produce with that of other people. What applies to the individual, applies in exactly the same way to the nation. There is no reason to desire that a nation should itself produce all the goods of which it has need; it is better that it should specialize upon those goods which it can produce to most advantage, and should exchange its surplus with the surplus of other goods produced by other countries. There is no use in sending goods out of the country except in order to get other goods in return. A butcher who is always willing to part with his meat but not willing to take bread from the baker, or boots from the bootmaker, or clothes from the tailor, would soon find himself in a sorry plight. Yet he would be no more foolish than the protectionist who desires that we should send goods abroad without receiving payment in the shape of goods imported from abroad.
The wage system has made people believe that what a man needs is work. This, of course, is absurd. What he needs is the goods produced by work, and the less work involved in making a given amount of goods, the better. But owing to our economic system, every economy in methods of production enables employers to dismiss some of their employees, and to cause destitution, where a better system would produce only an increase of wages or a diminution in the hours of work without any corresponding diminution of wages.
Our economic system is topsyturvy. It makes the interest of the individual conflict with the interest of the community in a thousand ways in which no such conflict ought to exist. Under a better system the benefits of free trade and the evils of tariffs would be obvious to all.
