action shall be guided by principles diametrically opposed to them. Assent to a declaration of the kind suggested would certainly affect the spirit in which international questions are approached in future, and probably the resulting action also. It runs: "The League to recognise that war from whatever cause is a danger to our common civilisation, and that international disputes ought to be settled on principles of right and justice and not by force of arms." The last clause dealing with the admission of new members of the League is the complement of this. There is to be power "to admit a nation as a member of the League, if satisfied in each case that the nation bona fide accepts the principle on which the League is founded, and bona fide intends that international disputes shall thereafter be settled by peaceful means." It is contemplated, and rightly contemplated, that there should be a possibility for the Central Empires to join the League sooner or later, but it can only be on terms of their rulers at the time saying expressly, "We abjure in the sight of the world and of our own people those principles of action which German rulers and leaders of thought have been inculcating for two generations." The choice for Germany would be either to stand excommunicated from the brotherhood of nations for ever, or to say plainly, "I declare what my professors and schoolmasters have for half a century had to teach to be false; the doctrines of Treitschke and of his disciple von Bernhardi are anathema; it is infamous to adopt the statement of the German writer that 'It is of no importance to me whether an action is just or unjust,' or that 'If I am powerful enough to perform any deed, then I am justified in doing it.' I renounce such leaders and teachers and all their words and works, so that I will not follow or be led by them." It may be urged that the recantation might not be sincere, but it would discredit the authority of those who attempt to revive the damnable doctrines.[2] The great difficulty, of course, arises as to the means of enforcing the agreement against war, of finding some proper and effective sanction to secure its observance. It may be well to note that throughout this discussion the word sanction is used in the strict legal sense, meaning some definite penalty or punishment to be inflicted on a wrong-doer. It is the existence of such a "sanction" which is the clearest way of enforcing obedience, and gives a rule of conduct the force of law.
