To some people the place of war in the economy of nations appears to be unsatisfactory. They think war wicked and a world where it exists out of joint. Accordingly they devote themselves to suggestions for the abolition of war and for the discovery of some substitute for it. Two theories are common; the first, that arbitration can in every case be a substitute for war, the second that the hopes of peace would be increased by some general agreement for disarmament.

The idea of those who regard arbitration as a universal substitute for war appears to be that the relations between States can be put upon a basis resembling that of the relations between citizens in a settled and civilised country like our own. In Great Britain we are accustomed to a variety of means for settling disagreements between persons. There are the law courts, there are the cases in which recourse is had, with the sanction of the law courts, to the inquiry and decision of an arbitrator, and in all our sports we are accustomed to the presence of an umpire whose duty it is impartially to see that the rules of the game are observed and immediately to decide all points that might otherwise be doubtful.

The work of an umpire who sees that the rules of the game are observed is based upon the consent of the players of both sides. Without that consent there could be no game, and the consent will be found to be based upon the fact that all the players are brought up with similar traditions and with like views of the nature of the game. Where this unity does not exist, difficulties constantly arise, as is notoriously the case in international sports. The attempt has been made, with constantly increasing success, to mitigate the evils of war by the creation of institutions in some way analogous to that of the umpire in a game. The Declaration of London, recently published, is an agreement between the principal Powers to accept a series of rules concerning maritime war, to be administered by an International Prize Court.

The function of an arbitrator, usually to decide questions of fact and to assess compensation for inconvenience, most commonly the inconvenience occasioned to a private person by some necessary act of the State, also rests upon the consent of the parties, though in this case the consent is usually imposed upon them by the State through some legislative enactment or through the decision of a court. The action of a court of law, on the other hand, does not rest upon the consent of the parties. In a civil action the defendant may be and very often is unwilling to take any part in the proceedings. But he has no choice, and, whether he likes it or not, is bound by the decision of the court. For the court is the State acting in its judicial capacity with a view to insure that justice shall be done. The plaintiff alleges that the defendant has done him some wrong either by breach of contract or otherwise, and the verdict or judgment determines whether or not this is the case, and, if it is, what compensation is due. The judgment once given, the whole power of the State will be used to secure its execution.

The business of a criminal court is the punishment of offenders whom it is the function of the State to discover, to bring to trial, and, when convicted, to punish. The prisoner's consent is not asked, and the judgment of the court is supported by the whole power of the State.

In the international sphere there is no parallel to the action either of a civil or of a criminal court. Civil and criminal jurisdiction are attributes of sovereignty, and over two independent States there is no sovereign power. If, therefore, it is desired to institute between two States a situation analogous to that by which the subjects of a single Government are amenable to judicial tribunals, the proper way is to bring the two States under one sovereignty. This can be effected, and is constantly effected, by one of two methods. Either the two States federate and form a united State, or one of them conquers and annexes the other. The former process has been seen in modern times in the formation of the United States of America: the latter formed the substance of the history of civilisation during the first three centuries before Christ, when the Roman State successively conquered, annexed, and absorbed all the other then existing States surrounding the basin of the Mediterranean.

The history of no State justifies the belief that order and justice can successfully be maintained merely by the action of umpires and of arbitrators. Every State worth the name has had to rely upon civil and criminal courts and upon law enforced by its authority, that is, upon a series of principles of right expressed in legislation and upon an organisation of force for the purpose of carrying those principles into practical effect.

It appears, then, that so far from the experience of States justifying the view that it is wrong to employ force, the truth is that right or law, unless supported by force, is ineffective, that the objection in principle to any use of force involves anarchy, or the cessation of the State, and that the wish to substitute judicial tribunals for war as a means of settling disputes between State and State is a wish to amalgamate under a single Government all those States which are to benefit by the substitution.

The reasonable attitude with regard to arbitration is to accept it whenever the other side will accept it. But if the adversary refuses arbitration and insists upon using force, what course is open to any State but that of resisting force by force?

Arbitration has from the earliest times been preferred in most of those cases to which it was applicable, that is, in cases in which there was a basis of common view or common tradition sufficient to make agreement practicable. But wherever there has been a marked divergence of ideals or a different standard of right, there has been a tendency for each side to feel that to submit its conscience or its convictions of right, its sense of what is most sacred in life, to an outside judgment would involve a kind of moral suicide. In such cases every nation repudiates arbitration and prefers to be a martyr, in case of need, to its sense of justice. It is at least an open question whether the disappearance of this feeling would be a mark of progress or of degeneration. At any rate it is practically certain that the period when it will have disappeared cannot at present be foreseen.

The abolition of war, therefore, involves the abolition of independent States and their amalgamation into one. There are many who have hoped for this ideal, expressed by Tennyson when he dreamed of

Proposals for disarmament stand on an entirely different footing from proposals to agree to arbitration. The State that disarms renounces to the extent of its disarmament the power to protect itself. Upon what other power is it suggested that it should rely? In the last analysis the suggestion amounts to a proposal for the abolition of the State, or its abandonment of its claim to represent the right. Those who propose agreements for disarmament imagine that the suggestion if adopted would lead to the establishment of peace. Have they considered the natural history of peace as one of the phenomena of the globe which we inhabit? The only peace of any value is that between civilised nations. It rests either upon the absence of dispute between them or upon an equilibrium of forces. During the last few centuries there has usually been at the end of a great European war a great European congress which has regulated for the time being the matters which were in dispute, and the treaty thus negotiated has remained for a long time the basis of the relations between the Powers. It is always a compromise, but a compromise more or less acceptable to all parties, in which they acquiesce until some change either by growth or decay makes the conditions irksome. Then comes a moment when one or more of the States is dissatisfied and wishes for a change. When that has happened the dissatisfied State attempts to bring about the change which it desires, but if the forces with which its wish is likely to be opposed are very great it may long acquiesce in a state of things most distasteful to it. Let there be a change in the balance of forces and the discontented State will seize the opportunity, will assert itself, and if resisted will use its forces to overcome opposition. A proposal for disarmament must necessarily be based upon the assumption that there is to be no change in the system, that the status quo is everywhere to be preserved. This amounts to a guarantee of the decaying and inefficient States against those which are growing and are more efficient. Such an arrangement would not tend to promote the welfare of mankind and will not be accepted by those nations that have confidence in their own future. That such a proposal should have been announced by a British Government is evidence not of the strength of Great Britain, not of a healthy condition of national life, but of inability to appreciate the changes which have been produced during the last century in the conditions of Europe and the consequent alteration in Great Britain's relative position among the great Powers. It was long ago remarked by the German historian Bernhardi that Great Britain was the first country in Europe to revive in the modern world the conception of the State. The feudal conception identified the State with the monarch. The English revolution of 1688 was an identification of the State with the Nation. But the nationalisation of the State, of which the example was set in 1688 by Great Britain, was carried out much more thoroughly by France in the period that followed the revolution of 1789; and in the great conflict which ensued between France and the European States the principal continental opponents of France were compelled to follow her example, and, in a far greater degree than has ever happened in England, to nationalise the State. It is to that struggle that we must turn if we are to understand the present condition of Europe and the relations of Great Britain to the European Powers.
