The motive of this desire for expansion, it is true, was in all cases chiefly an economic need. But the very fact that the various efforts at expansion, at least in their early stages, found almost always popular approval, shows that there usually was a secondary motive, a desire for aggrandizement. For it is very rare, indeed, that public opinion possesses sufficient foresight to either appreciate or be guided by economic necessities, while undertakings which can be made to appeal to the sentiments of jealousy, of nationalism, and of rivalry, readily find public support. The second of these--nationalism--especially was reawakened and in many an instance grew into chauvinism, endangering frequently the peace of the world. This, in a way, was very remarkable; for hand in hand with the increase of nationalism went an increase of internationalism to a degree that never before had been achieved in the history of the world. Indeed, for a considerable period it looked as if the world nations were rapidly approaching that happy state when war would be unnecessary because a peaceful method of adjusting international difficulties had been found and had been universally adopted. Whether the Great War of 1914 has destroyed all that was accomplished in the years preceding to make peace lasting, or whether it was only one of the obstacles in the path of this revolutionary undertaking, remains to be seen. The international cooperation of which we have just spoken was, of course, nothing new. For treaties have been signed and alliances have been concluded between nations ever since they have been developed far enough to be capable of definite, deliberate political efforts. But never before have treaties and alliances been so plentiful or gone so far, and only rarely have they resulted in such a definite alignment of the European nations into two groups. The inception of this policy the world owes to the great modern German statesman, Bismarck. It was through his efforts that the Triple Alliance was created soon after the Franco-Prussian War and after the foundation of the new German Empire which chose as its companions Austria-Hungary and Italy. That Bismarck built well then is clearly shown by the wonderful progress that Germany especially has been able to make since the Triple Alliance was founded and insured European peace for a long period of years. But that either he did not build well enough for all exigencies or else that his successors were not as capable as he, is shown equally clearly by the fact that at the most crucial moment in Germany's modern history one member of the Triple Alliance, Italy, deserted. The second group of European nations, in a way, was the logical result of the first, for the latter, as it were, left high and dry on the sea of international cooperation the three powerful countries of England, France, and Russia. At the time of the formation of the Triple Alliance France, of course, was disabled through its defeat by
