Often it has been asserted that if the United States had stood by her allies after 1918 and joined the League of Nations, peace in Europe would have been secure. While this overstresses the point, it is certainly true that the lack of unity among the victors, both at Versailles and afterwards, deprived the world of anything like a center of coördination and leadership. Even the Concert of Europe of bygone days could claim greater authority than a League from which five out of seven great powers were either permanently or temporarily absent, and in which the two remaining powers, Britain and France, were rarely in agreement.

In view of this experience, it makes sense to regard continued coöperation between at least some of the important allies of this war, assuming the defeat of Hitler and his partners, as being an essential prerequisite for a more durable peace. If at least the two great English-speaking powers could form between themselves a solid partnership, so it is argued, would not their combined strength and their supremacy of the seas quite naturally attract other nations into their orbit and thus enable them to preserve the order and peace of the world? Their rôle is envisaged as a kind of enlarged replica of that which the British Empire fulfilled with no little success throughout most of the nineteenth century.
