Assuming that the members of the League included all or most of the important commercial and financial nations, and that they could be relied upon to press energetically all or even a few of these forms of boycott, could any country long resist such pressure? Would not the threat of it and the knowledge that it could be used form a potent restraint upon the law-breaker? Even the single weapon of a complete postal and telegraphic boycott would have enormous efficiency were it rigorously applied. Every section of the industrial and commercial community would bring organized pressure upon its Government to withdraw from so intolerable a position and to return to its international allegiance. It may be said, Why is it that such a powerful weapon of such obvious efficacy has never been applied? The answer is that the conditions for its rapid and concerted application have never hitherto existed. For in order that it may be effective, a considerable number of nations must have previously undertaken to apply it simultaneously and by common action. And, what is more, each nation must have confidence in the _bona fides_ of the intention of other nations to apply it. For the detailed application of the boycott, in most points, must of necessity remain in the hands of the several national Governments. Here comes the practical difficulty. Every boycott has a certain injurious rebound. It hits back the nation that applies it. The injury of suspended intercourse is, of course, not equal, otherwise the process would be futile. If the whole circle of A’s neighbors boycott him, each suffers half the loss of his separate intercourse with A, but A suffers this loss multiplied by the number of his neighbors. Now if A’s intercourse with all his neighbors is of equal magnitude, each of them can probably afford easily to bear the sacrifice involved in the boycott, trusting to the early effect of their action in bringing A to terms. But if one or two of A’s neighbors are in much closer relations with A than the others, and if, as may be the case, they are getting more advantage from this intercourse than A, the risk or sacrifice they are called upon to undergo will be proportionately greater. They must bear the chief brunt of a policy in the adoption of which they have not the determinant voice. Take, for example, the case of Germany. An all-round boycott applied to her would evidently cause more damaging reactions to Holland, Belgium, and Denmark than to any of the greater nations whose united voice might have determined its application. The injury to Holland, in particular, might in the first instance be almost as grave as that sustained by Germany, the supposed object of the boycott. It would evidently be necessary to make provision against this unequal incidence by devising a system of compensations or indemnity to meet the case of such a special injury or sacrifice.
