For the States entering such a League will be of various grades of political development: some may enter with reluctance and rather because they fear to be left out than because they believe in or desire the success of the League. It is idle to imagine that a society starting with so little inner unity of status and of purpose can dispense entirely with the backing of physical force with which the most highly evolved of national societies has been unable to dispense. [Sidenote: How constituted.] What form, then, should the required international force take, and who should exercise it? The proposal to endow some executive international body with the power of levying and maintaining a new land and sea force, superior to that of any Power or combination it may be called upon to meet, scarcely merits consideration. Apart from the hopelessness of getting the Powers to consent to set up a Super-State upon this basis, the mere suggestion of curing militarism by creating a large additional army and navy would be intolerable. Nor is it any more reasonable to expect the Powers to abandon their separate national forces, simply contributing their quota towards an international force under the permanent control of an International Executive. No such abandonment of sovereign power, no such complete confidence in the new internationalism, could for a long time to come be even contemplated. Each nation would insist upon retaining within its own territory and at its own disposal the forces necessary to preserve internal order and to meet at the outset any sudden attack made from outside. It is evident, in other words, that the forces required by the International League in the last resort, for the maintenance of public law and the repression of breaches of the treaty, must be composed of contingents drawn upon some agreed plan from the national forces and placed for the work in hand at the disposal of an international command. Such armed cooperation is, of course, not unknown. Several times within recent years concerted action has been taken by several European Powers, and though the Pekin expedition in 1900 cannot be regarded as a very favorable example, it illustrates the willingness of Powers to act together for some common end which seems to them of sufficient importance. Is it too much to expect that the nations entering the Confederation will realize with sufficient clearness the importance of preserving the integrity of their international agreement to be willing to entrust a permanent executive with the duty of commandeering the forces necessary to achieve this purpose when they may be required? [Sidenote: Armies and navies must be held in trust for the world-community. Each nation would get more security at less cost.]
