Almost everybody hopes that, when this war is over, it will be possible to secure the conditions of a lasting peace by reducing the power of militarism and by setting the relations between nations on a better footing. To watchers of the present conflict it seems an intolerable thought that, after the fighting is done, we should once more return to a condition of “armed peace,” with jealous, distrustful, and revengeful Powers piling up armaments and plotting singly or in groups against their neighbors until Europe is plunged into another war more terrible, more bloody, and more costly than this. Yet nothing is more certain than that this will happen unless the Peoples which are so vitally concerned are able to mobilize their powers of clear thought, sane feeling, and goodwill in carefully considered plans for a cooperative policy of nations. [Sidenote: The peril of “crushing” Germany.] The first great obstacle to the performance of this task is the state of mind of those who seem to think that all that is required is “to crush German militarism,” and that, this incubus once removed, the naturally pacific disposition of all other nations will dispose them to live together in amity. It is not easy to induce such persons to consider closely what they mean by “crushing German militarism,” or how its destruction, whatever it does mean, would secure the peace of Europe, we will not say in perpetuity, but for a single generation. But let us suppose the most complete success for the arms of the Allies, the slaughter or the capture of great German forces, the invasion of Germany, and the dictation of terms of peace by the Allies at Berlin. Such terms as were imposed might cripple her military power of aggression or revenge for some years. But would it kill what we know as German militarism? If our accepted political analysis be right, the German militarism that must be crushed is not an army and a navy, but a spirit of national aggression, proud, brutal, and unscrupulous, the outcome of certain intellectual and moral tendencies embodied in the “real” politics and the “real” culture of the nation. Can we seriously suppose that this evil spirit will be exorcised by a crushing defeat on land and sea, followed by a humiliating peace? If Germany could be permanently disabled from entertaining any hopes of recovering her military strength, or from exercising any considerable influence in the high policy of Europe, her feelings of resentment and humiliation might perhaps be left to rankle in impotence, or to die out by lapse of time. But nothing which the Allies can do to Germany will leave her in such long-lasting impotence. Even if stripped of her non-Teutonic lands and populations, she will remain a great Power—great in area, population, industry, and organizing power—and no temporary restrictions or guarantees can long prevent her from once more developing a military strength that will give dangerous meaning to her thirst for vengeance.
