Advantages of pledges.

A conference is an excellent thing. The proposal of a league to enforce peace by no means excludes it; but the important matter, the effective principle, is that every member of the league should know that whether a conference meets or not, or whatever action it may take or fail to take, all the members of the league have pledged themselves to declare war forthwith on any member that commits a breach of the peace before submitting its case to the international tribunal or council of conciliation. Such a pledge, and such a pledge alone, can have the strong deterrent influence, and thus furnish the sanction, that is needed. Of course the pledge may not be kept. Like other treaties it may be broken by the parties to it. Nations are composed of human beings with human weaknesses, and one of these is a disinclination to perform an agreement when it involves a sacrifice. Nevertheless, nations, like men, often do have enough sense of honor, of duty, or of ultimate self-interest, to carry out their contracts at no little immediate sacrifice. They are certainly more likely to do a thing if they have pledged themselves to it than if they have not; and any nation would be running a terrible risk that went to war in the hope that the other members of the league would break their pledges.

The threats of universal war and boycott.

The same objection applies to another alternative proposed in place of an immediate resort to military force: that is the use of economic pressure, by a universal agreement, for example, to have no commercial intercourse with the nation breaking the peace. A threat of universal boycott is, no doubt, formidable, but by no means so formidable as a threat of universal war. A large country with great natural resources which has determined to make war, might be willing to face commercial non-intercourse with the other members of the league during hostilities, when it would not for a moment contemplate the risk of fighting them. A threat, for example, by England, France, and Germany to stop all trade with the United States might or might not have prevented our going to war with Spain; but a declaration that they would take part with all their armies and navies against us would certainly have done so.

It has often been pointed out that the threat of general non-intercourse would bear much more hardly on some countries than on others. That may not in itself be a fatal objection, but a very serious consideration arises from the fact that there would be a premium on preparation for war. A nation which had accumulated vast quantities of munitions, food, and supplies of all kinds, might afford to disregard it; while another less fully prepared could not.

Moreover, economic pressure, although urged as a milder measure, is in fact more difficult to apply and maintain. A declaration of war is a single act, and when made sustains itself by the passion it inflames; while commercial non-intercourse is a continuous matter, subject to constant opposition exerted in an atmosphere relatively cool. Our manufacturers would complain bitterly at being deprived of dye-stuffs and other chemical products on account of a quarrel in which we had no interest; the South would suffer severely by the loss of a market for cotton; the shipping firms and the exporters and importers of all kinds would be gravely injured; and all these interests would bring to bear upon Congress a pressure well-nigh irresistible. The same would be true of every other neutral country, a fact that would be perfectly well known to the intending belligerent and reduce its fear of a boycott.

Drastic threats by a League could probably prevent war.

But, it is said, why not try economic pressure first, and, if that fails, resort to military force, instead of inflicting at once on unoffending members of the league the terrible calamity of war? What do we mean by “if that fails”? Do we mean, if, in spite of the economic pressure, the war breaks out? But then the harm is done, the fire is ablaze and can be put out only by blood. The object of the league is not to chastise a country guilty of breaking the peace, but to prevent the outbreak of war, and to prevent it by the immediate prospect of such appalling consequences to the offender that he will not venture to run the risk. If a number of great Powers were to pledge themselves with serious intent, to wage war jointly and severally on any one of their members that attacked another before submitting the case to arbitration, it is in the highest degree improbable that the casus fœderis would ever occur, while any less drastic provision would be far less effective.

Object is to lessen chances of war, though the League could not meet all possible contingencies.

An objection has been raised to the proposal for a league to enforce peace on the ground that it has in the past often proved difficult, if not impossible, to determine which of two belligerents began a war. The criticism is serious, and presents a practical difficulty, grave but probably not insurmountable. The proposal merely lays down a general principle, and if adopted the details would have to be worked out very fully and carefully in a treaty, which would specify the acts that would constitute the waging of war by one member upon another. These would naturally be, not the mere creating of apprehension, but specific acts, such as a declaration of war, invasion of territory, the use of force at sea not disowned within forty-eight hours, or an advance into a region in dispute. This last is an especially difficult point, but those portions of the earth’s surface in which different nations have conflicting claims are growing less decade by decade.
