In assessing the early value of all proposals for better international relations, the best practical test is afforded by the question, 'Will the proposal lead nations to reduce their armaments?' For it will be admitted that any settlement or international agreement, which leaves the claims of militarism and navalism upon the vital and financial resources of the several nations unimpaired, affords little hope of a pacific future. A return to the era of competing armaments will destroy the moral strength of any formal international agreements, however specious. The importance of this consideration has led many to insist that an explicit agreement for proportional disarmament should take a prominent place in any settlement. This proposal, however, seems to me defective in that it presumes in all or some of the nations a persistence of the motives which have hitherto led them to strengthen their fighting forces. Now the primary object of such international arrangements as we are discussing, is to bring about a state of things in which the past motives to arm will weaken and tend to disappear. If nations, actuated either by arrogance or greed or fear, continue to desire to increase their fighting strength, no arrangements for proportionate disarmament are likely to be effective. On the other hand, if the basis of a really valid league or federation can be laid, precluding the most ambitious State from any reasonable hope of indulging dreams of successful conquest, while relieving timid States from the apprehensions under which they have lived hitherto, the natural play of political forces within each State will favour disarmament. An international arrangement that meets our requirements must be strong enough to reverse the motives, aggressive and defensive, which in the past have caused nations to arm. Nations will not pile up armaments if they believe that they will have no need or opportunity to use them. To produce this belief in the uselessness of national armies and navies is therefore a prime object of international policy. The successful establishment of this belief involves, however, a change of disposition among national governments amounting to the process known in religious circles as conversion. They must be induced to forgo that right of war which according to past statecraft has been the brightest jewel in the crown of sovereignty.
