Take the case of Austria under the new conditions, with a thick population concentrated in a great political capital suddenly deprived of all free access to its former sources of supply and the markets it used to serve. For her it is a sentence of economic strangulation. Here is an extreme instance of the effect of economic isolation on a weak country. But the dangerous truth may be more broadly stated. A very few great empires and nations today control the whole available supplies of many of the foods, fabrics, and metals, the shipping and finance, that are essential to the livelihood and progress of every civilized people. Are Britain, America, France, and Japan--and especially the two greatest of these powers--going to absorb or monopolize for their exclusive purposes of trade or consumption these supplies which every country needs, or are they going to let the rest of the world have fair access to them? I think this to be upon the whole the most important of the many urgent issues that confront us. For, if close nationalism or imperialism should prevail, the weaker placed nations could not acquiesce. Close economic nationalism is not for them a possibility. They must win access to the world's supplies, peacefully if possible, or else by force. The fatality of the great choice is thus evident. Nations must and will fight for the means of life. Close economic nationalism or imperialism on the part of the great empires must, therefore, compel the restricted countries to organize force for their economic liberation. This in turn will compel the great empires to maintain strong military and naval defences. It is impossible for the other nations of the earth to leave the essential supplies of metals, foods, and oils, and the control of transport in the exclusive possession of one or a few close national corporations or a permanent "Big Four." Under such conditions the sacrifices of the great war would have been made in vain. Nothing would have been done to end war, or to rescue the world from the burden of militarism. The pre-war policy of contending alliances and of competing armaments, draining more deeply than ever the surplus incomes of each people, would be resumed. And it would bring no sense of security, but only the postponement of further inevitable conflicts in which the very roots of western civilization might perish. The renewed and intolerable burdens of such a militarism, with its accompaniments of autocracy, must let loose class war in every nation which has gone through the agony of the European struggle and has seen the great hope of a peaceful internationalism blighted.
