The great advantage of a large military State is that it increases the area over which internal war is not possible except by revolution. If England and Canada have a disagreement, it is taken as a matter of course that a settlement shall be arrived at by discussion, not by force. Still more is this the case if Manchester and Liverpool have a quarrel, in spite of the fact that each is autonomous for many local purposes. No one would have thought it reasonable that Liverpool should go to war to prevent the construction of the Manchester Ship Canal, although almost any two Great Powers would have gone to war over an issue of the same relative importance. England and Russia would probably have gone to war over Persia if they had not been allies; as it is, they arrived by diplomacy at much the same iniquitous result as they would otherwise have reached by fighting. Australia and Japan would probably fight if they were both completely independent; but both depend for their liberties upon the British Navy, and therefore they have to adjust their differences peaceably. The chief disadvantage of a large military State is that, when external war occurs, the area affected is greater. The quadruple Entente forms, for the present, one military State; the result is that, because of a dispute between Austria and Serbia, Belgium is devastated and Australians are killed in the Dardanelles. Another disadvantage is that it facilitates oppression. A large military State is practically omnipotent against a small State, and can impose its will, as England and Russia did in Persia and as Austria-Hungary has been doing in Serbia. It is impossible to make sure of avoiding oppression by any purely mechanical guarantees; only a liberal and humane spirit can afford a real protection. It has been perfectly possible for England to oppress Ireland, in spite of democracy and the presence of Irish Members at Westminster. Nor has the presence of Poles in the Reichstag prevented the oppression of Prussian Poland. But democracy and representative government undoubtedly make oppression less probable: they afford a means by which those who might be oppressed can cause their wishes and grievances to be publicly known, they render it certain that only a minority can be oppressed, and then only if the majority are nearly unanimous in wishing to oppress them. Also the practice of oppression affords much more pleasure to the governing classes, who actually carry it out, than to the mass of the population. For this reason the mass of the population, where it has power, is likely to be less tyrannical than an oligarchy or a bureaucracy.
