When all nations realize that if England can no longer exert force towards her Colonies, others certainly could not; that if a great modern Empire cannot usefully employ force as against communities that it "owns," still less can we employ it usefully against communities that we do not "own"; when the world as a whole has learned the real lesson of British Imperial development, not only will that Empire have achieved greater security than it can achieve by battleships, but it will have played a part in human affairs incomparably greater and more useful than could be played by any military "leadership of the human race," that futile duplication of the Napoleonic rôle, which Imperialists of a certain school seem to dream for us.
It is to Anglo-Saxon practice, and to Anglo-Saxon experience, that the world will look as a guide in this matter. The extension of the dominating principle of the British Empire to European society as a whole is the solution of the international problem which this book urges. That extension cannot be made by military means. The English conquest of great military nations is a physical impossibility, and it would involve the collapse of the principle upon which the Empire is based if it were. The day for progress by force has passed; it will be progress by ideas or not at all.
Because these principles of free human co-operation between communities are, in a special sense, an Anglo-Saxon development, it is upon us that there falls the responsibility of giving a lead. If it does not come from us, who have developed these principles as between all the communities which have sprung from the Anglo-Saxon race, can we ask to have it given elsewhere? If we have not faith in our own principles, to whom shall we look?
