The foreign capitalists appealed to their governments; commercial imperialism responded by dispatching military forces to protect the lives and “property” of its citizens, in some instances going so far as to take possession of the country. A classic case, as cited by Hobson, is Britain’s South African War, in which the blood and treasure of the people of the United Kingdom were expended because British capitalists had found the Boers recalcitrant, bent on retaining their own country for themselves. To be sure, South Africa, like Mexico is rich in resources for which advancing civilization continually makes demands. And, in the case of Mexico, the products of the tropics, such as rubber, are increasingly necessary to the industrial powers of the temperate zone. On the other hand, if the exploiting nation aspire to self-government, the imperialistic method of obtaining these products by the selfish exploitation of the natural and human resources of the backward countries reacts so powerfully on the growth of democracy at home--and hence on the growth of democracy throughout the world--as to threaten the very future of civilization. The British Liberals, when they came into power, perceived this, and at once did their best to make amends to South Africa by granting her autonomy and virtual independence, linking her to Britain by the silken thread of Anglo-Saxon democratic culture. How strong this thread has proved is shown by the action of those of Dutch blood in the Dominion during the present war. Eventually, if democracy is not to perish from the face of the earth, some other than the crude imperialistic method of dealing with backward peoples, of obtaining for civilization the needed resources of their lands, must be inaugurated--a democratic method. And this is perhaps the supreme problem of democracy today. It demands for its solution a complete reversal of the established policy of imperialism, a new theory of international relationships, a mutual helpfulness and partnership between nations, even as democracy implies cooperation between individual citizens. Therefore President Wilson laid down the doctrine that American citizens enter Mexico at their own risk; that they must not expect that American blood will be shed or the nation’s money be expended to protect their lives or the “property” they have acquired from Mexican dictators. This applies also to the small capitalists, the owners of the coffee plantations, as well as to those Americans in Mexico who are not capitalists but wage earners. The people of Mexico are entitled to try the experiment of self-determination. It is an experiment, we frankly acknowledge that fact, a democratic experiment dependent on physical science, social science, and scientific education. The other horn of the dilemma, our persistence in imperialism, is even worse--since by such persistence we destroy ourselves.
