That lesser form of self-government might be sought in a local autonomy under a federal government. It is not improbable that the political development, of south-eastern Europe for example, will tend towards group organisations based on the co-operation of diverse nationalities and stocks somewhat on the Swiss model. If the political question could be divorced from the question of the economic exploitation of these small nations, and if each nationalistic group were permitted to retain its language, traditions and Kultur, the result might be better than a mere morcellement of south-eastern Europe, with petty nationalities fighting the battles of their big backers. In such a larger Switzerland, each group might be represented in proportion to its numbers, and the worst evils of the present racial contests be avoided.

The important question in the present connection, however, is not what the particular solution is to be, but whether any solution is possible. It need not be a perfect but only a permanent settlement. Such a settlement presupposes a concert among the Great Powers, an agreement concerning their own problems. Given such an agreement, however, the Powers could in time work out a Balkan arrangement, which neither Servia nor Bulgaria, Roumania nor Greece would dare resist. In the end, if the arrangement were definite, practicable, in reasonable conformity with nationalistic lines, and with a strong and certain sanction, the small nations would become resigned. To-day they have boundless ambitions because the division among the Great Powers gives them a chance of realising ambitions, and what ambitions they have not to start with, Austria or Russia will lend to them on short notice. In this sense and to this extent, the nationalistic problem in its worst form is an appendage to the vast struggle between the powers, and it may cease to be provocative of great wars once a basis of agreement is established among these larger nations.

With the best will such a basis of international agreement among the Great Powers cannot be established in a few years. It requires a gradual development, a progressive give and take, a continuous widening of the principle of joint use. An international convention, altering the rules of maritime warfare, would be a long step in this direction; a congress of the nations for opening up the trade of colonies (like our international postal conventions) would be another step. The internationalisation of Panama, Kiel, Gibraltar, Constantinople, would immensely enhance security, and advance the progress of internationalisation. So also an economic convention between France and Germany, or between Germany and Russia, in which reciprocal industrial advantages were accorded. Such specific arrangements, which permit of international interpretation and enforcement, would help to bring about a larger economic internationalism.

But for the real foundations of peace we must look far below the level of all these diplomatic and political arrangements, in the world industry itself. To-day we are still in the full momentum of an economic development that makes for war, but we are also at the beginning of an economic trend towards peace. In the present world-economy the nation is the unit and international friction the rule, but the movement, at what rate we do not know, tends towards a world business in which the unit will be international and there will be peace between partners. We are already in the first beginnings of the internationalism of capital.

This development is in part the cause of a general phenomenon, the growth of an internationalism of class. Each social group seeks to establish relations with similar groups across the border, for the protection of interests that traverse national boundaries. Thus we have a certain internationalism of the wage-earning class, of finance, of various scientific groups. The possibility of this internationalism grows with the integration of the world through commerce, industry, communication and the spread of knowledge.

The most obviously international of social groups is the proletariat. Though sundered on the question of immigration, though (in some countries) nationalistic and even militaristic in spirit, the wage-earners on the whole have less to gain from imperialism and national aggression than have wealthier classes, while they share disproportionately in the burdens that war entails. On the other hand workers have less influence in the making of diplomatic decisions than do their employers. In the end, moreover, their decision, like that of the capitalist class, is chiefly determined by economic forces largely beyond their control. It is the nascent internationalism of capital, not of capitalists or of wage-earners, that is the supreme element making for peace.

We must beware, however, of welcoming all foreign investment as a portent of a growing internationalism of capital. Much that is accounted economic internationalism is in truth merely an extended nationalism, an extra-nationalism. For investments to allay international discord they should create a community of interest between nations potentially hostile. If Britain invested freely in Germany and Germany in Britain there would be created a mutuality of interest which would render peace probable. Each nation would have a stake in the prosperity of the other; each would have given hostages to peace. But when the London financier puts his money in India, Canada or the Argentine, he is not co-operating but competing with potentially hostile nations. The process is an extension of the national economy to outlying districts, a transition to a larger national unit, like that created in the Middle Ages when the free cities ruled adjoining farm territory. Such an economic extension exacerbates national antagonisms and leads to war.

While foreign investment is preponderatingly of this sort, however, there also exist the beginnings of a movement more truly international. The securities of one nation are dealt with upon the stock exchanges of another, capital flows across national borders and great international business concerns are created. The movement in favourable circumstances is likely to accelerate, either by the mutual economic interpenetration of nations, as when the French build factories in Germany or the Germans in France, or by the amalgamation of the capitals of two countries and their use in joint enterprises. The formation of large international syndicates for the exploitation of backward countries, whatever its other consequences, tends towards the creation of a community of interest. If the powers unite, for example, and can agree upon a Chinese loan, a step forward will have been taken towards an internationalism of capital.

The process of trust formation tends in the same direction. As competing industries within a nation frequently end by combining, so in many great industries the competing national units may develop a gentleman's agreement to regulate output and finally may establish an international cartel. Considerable progress has already been made in the division of the international field. A further development along these lines, though not easy, is by no means impossible or even improbable.
