War either with Japan or Britain or both is, of course, quite within the region of possibility. It is merely an evasion of the trouble which facing reality always involves, to say that war between Britain and America is "unthinkable." If any war, as we have known it these last ten years, is thinkable, war between nations that have already fought two wars is obviously not unthinkable. And those who can recall at all vividly the forces which marked the growth of the conflict between Britain and Germany will see just those forces beginning to colour the relations of Britain and America. Among those forces none is more notable than this: a disturbing tendency to stop short at the ultimate questions, a failure to face the basic causes of divergence. Among people of good will there is a tendency to say: "Don't let's talk about it. Be discreet. Let us assume we are good friends and we shall be. Let us exchange visits." In just such a way, even within a few weeks of war, did people of good will in England and Germany decide not to talk of their differences, to be discreet, to exchange visits. But the men of ill will talked--talked of the wrong things--and sowed their deadly poison. These pages suggest why neither side in the Anglo-German conflict came down to realities before the War. To have come to fundamentals would have revealed the fact to both parties that any real settlement would have asked things which neither would grant. Really to have secured Germany's future economic security would have meant putting her access to the resources of India and Africa upon a basis of Treaty, of contract. That was for Britain the end of Empire, as Imperialists understood it. To have secured in exchange the end of "marching and drilling" would have been the end of military glory for Prussia. For both it would have meant the surrender of certain dominations, a recasting of patriotic ideals, a revolution of ideas. Whether Britain and America are to fight may very well depend upon this: whether the blinder and more unconscious motives rooted in traditional patriotisms, and the impulse to the assertion of power, will work their evil before the development of ideas has brought home to us a clearer vision of the abyss into which we fall; before we have modified, in other words, our tradition of patriotism, our political moralities, our standard of values. Without that more fundamental change no scheme of settlement of specific differences, no platforms, Covenants, Constitution can avail, or have any chance of acceptance or success. As a contribution to that change of ideas and of values these pages are offered. SUMMARY OF ARGUMENT
