Until we have managed somehow to create an economic code or comity which makes the sovereignty of each nationality subject to the general need of the whole body of organised society, this struggle, in which nationality is for ever threatened, will go on. The alternatives were very clearly stated on the other side of the Atlantic:-- 'The underlying assumption heretofore has been that a nation's security and prosperity rest chiefly upon its own strength and resources. Such an assumption has been used to justify statesmen in attempting, on the ground of the supreme need for national security, to increase their own nation's power and resources by insistence upon strategic frontiers, territory with raw material, outlets to the sea, even though that course does violence to the security and prosperity of others. Under any system in which adequate defence rests upon individual preponderance of power, the security of one must involve the insecurity of another, and must inevitably give rise to covert or overt competitions for power and territory, dangerous to peace and destructive to justice. 'Under such a system of competitive as opposed to co-operative nationalism, the smaller nationalities can never be really secure. International commitments of some kind there must be. The price of secure nationality is some degree of internationalism. 'The problem is to modify the conditions that lead to war. It will be quite inadequate to establish courts of arbitration or of law if they have to arbitrate or judge on the basis of the old laws and practices. These have proved insufficient. 'It is obvious that any plan ensuring national security and equality of opportunity will involve a limitation of national sovereignty. States possessing ports that are the natural outlet of a hinterland occupied by another people, will perhaps regard it as an intolerable invasion of their independence if their sovereignty over those ports is not absolute but limited by the obligation to permit of their use by a foreign and possibly rival people on equal terms. States possessing territories in Africa or Asia inhabited by populations in a backward state of development, have generally heretofore looked for privileged and preferential treatment of their own industry and commerce in those territories. Great interests will be challenged, some sacrifice of national pride demanded, and the hostility of political factions in some countries will be aroused.
