When criticizing the different military systems, we must remember that with growing civilization the requisite military capacities are always changing. The duties expected from the Roman legionary or the soldiers who fought in line under Frederick the Great were quite different from those of the rifleman and cavalryman of to-day. Not merely have the physical functions of military service altered, but the moral qualities expected from the fighting man are altered. This applies to the individual soldier as much as to the whole army. The character of warfare has continually been changing. To fight in the Middle Ages or in the eighteenth century with comparatively small forces was one thing; it is quite another to handle the colossal armies of to-day. The preparations for war, therefore, in the social as well as military sense, must be quite different in a highly developed modern civilized State from those in countries, standing on a lower level of civilization, where ordinary life is full of military elements, and war is fought under relatively simple conditions.
The crushing superiority of civilized States over people with a less developed civilization and military system is due to this altered form of military efficiency. It was thus that Japan succeeded in raising herself in a brief space to the supremacy in Eastern Asia. She now reaps in the advancement of her culture what she sowed on the battlefield, and proves once again the immeasurable importance, in its social and educational aspects, of military efficiency. Our own country, by employing its military powers, has attained a degree of culture which it never could have reached by the methods of peaceful development.
When we regard the change in the nature of military efficiency, we find ourselves on ground where the social duty of maintaining the physical and moral power of the nation to defend itself comes into direct contact with the political duty of preparing for warfare itself.
A great variety of procedure is possible, and actually exists, in regard to the immediate preparations for war. This is primarily expressed in the choice of the military system, but it is manifested in various other ways. We see the individual States—according to their geographical position, their relations to other States and the military strength of their neighbours, according to their historic claims and their greater or less importance in the political system of the world—making their military preparations with more or less energy, earnestness, and expenditure. When we consider the complex movements of the life of civilized nations, the variety of its aims and the multiplicity of its emotions, we must agree that the growth or decrease of armaments is everywhere affected by these considerations. War is only a means of attaining political ends and of supporting moral strength.
Thus, if England attaches most weight to her navy, her insular position and the wide oversea interests which she must protect thoroughly justify her policy. If, on the other hand, England develops her land forces only with the objects of safeguarding the command of her colonies, repelling a very improbable hostile invasion, and helping an allied Power in a continental war, the general political situation explains the reason. As a matter of fact, England can never be involved in a great continental European war against her will.
So Switzerland, which has been declared neutral by political treaties, and can therefore only take the field if she is attacked, rightly lays most stress on the social importance of military service, and tries to develop a scheme of defence which consists mainly in increasing the security afforded by her own mountains. The United States of America, again, are justified in keeping their land forces within very modest limits, while devoting their energies to the increase of their naval power. No enemy equal to them in strength can ever spring up on the continent of America; they need not fear the invasion of any considerable forces. On the other hand, they are threatened by oversea conflicts, of epoch-making importance, with the yellow race, which has acquired formidable strength opposite their western coast, and possibly with their great trade rival England, which has, indeed, often made concessions, but may eventually see herself compelled to fight for her position in the world.
While in some States a restriction of armaments is natural and justifiable, it is easily understood that France must strain every nerve to secure her full recognition among the great military nations of Europe. Her glorious past history has fostered in her great political pretensions which she will not abandon without a struggle, although they are no longer justified by the size of her population and her international importance. France affords a conspicuous example of self-devotion to ideals and of a noble conception of political and moral duties.
In the other European States, as in France, external political conditions and claims, in combination with internal politics, regulate the method and extent of warlike preparations, and their attitude, which necessity forces upon them, must be admitted to carry its own justification.
A State may represent a compact unity, from the point of view of nationality and civilization; it may have great duties to discharge in the development of human culture, and may possess the national strength to safeguard its independence, to protect its own interests, and, under certain circumstances, to persist in its civilizing mission and political schemes in defiance of other nations. Another State may be deficient in the conditions of individual national life and in elements of culture; it may lack the resources necessary for the defence and maintenance of its political existence single-handed in the teeth of all opposition. There is a vast difference between these two cases.
A State like the latter is always more or less dependent on the friendliness of stronger neighbours, whether it ranks in public law as fully independent or has been proclaimed neutral by international conventions. If it is attacked on one side, it must count on support from the other. Whether it shall continue to exist as a State and under what conditions must depend on the result of the ensuing war and the consequent political position—factors that lie wholly outside its own sphere of power.
