The French, in their attitude to making peace, were...preoccupied with the question of Germany's power in the future; a future which they saw as one … - Correlli Barnett

British policy was therefore the child of their insemination of the politicians – politicians like Baldwin and MacDonald, the Chamberlains, Simon and Henderson, Halifax, Eden. It was as if the encumbents of quiet early-nineteenth-century rectories and nonconformist minister's houses had been miraculously transported into the great offices of State of a hundred years later. Instead of the suspicious minds of pre-Victorian statesmen, there was trustfulness; instead of a worldly scepticism, a childlike innocence and optimism. And instead of a toughness, even a ruthlessness, in the pursuit of English interests, there was a yielding readiness to appease the wrath of other nations. For the very bedrock of the national character had been crumbled since the eighteenth century. Whereas the pre-Victorian Englishman had been renowned for his quarrelsome temper and his willingness to back his argument with his fists – or his feet – now the modern British, like the elderly, shrank from conflict or unpleasantness of any kind. In Lord Vansittart's words: "Right or Left, everybody was for a quiet life."

Two things caused the decadence of British maritime power: the long peaceful supremacy after Trafalgar and the capture of the navy by that hierarchy of birth and class that controlled so many of Britain's national institutions. Drawing most of its officers from 1 per cent of the nation, the Royal Navy never tapped that great reservoir of urban middle-class talent that made Scheer's fleet so well-educated and so intelligent... The navy reflected social rather than functional values, preoccupation with tradition rather than technology... It was a tragedy for Britain that the aristocracy and gentry had never been cut off from the national life, as had largely happened in France... [T]he social and intellectual values of industrial society never ousted those of the aristocracy. The richer Victorian England became, the more ashamed in a deep sense did she become of the technological origin of those riches. The engineer and the businessman have never been as "respectable" in Britain as in Germany or America... [I]n the world after 1870, when Britain faced the technical challenges of the more complex phase of the industrial revolution and the commercial challenge of foreign competition, the leadership of the country was in the hands of the social group least likely (because of its wealth and privilege) to be aware of the challenges and to respond to them. From 1870 to 1914 Britain was decadent because a decadent ruling social group and decadent (non-functional) values had captured or corrupted the forces of technological and social change.

"Niceness", the desire "to do the decent thing" – these qualities constituted then, and still constitute today, the emotional essence of small 'l' liberalism. They are qualities desirable in a friend, a neighbour or a colleague, and admirable in the citizen of a democracy. But they serve ill as a guide to a nation's total strategy in a ruthless world of struggle. The dominance of these qualities over the British public mind and feelings therefore accounts more than any other factor for the contrast between British power in 1918 and British power in 1956. For the desire to be "nice" and "do the decent thing" lay at the heart of "appeasement", whether of dictators in the 1930s or trade unions in the 1940s and 1950s; it explains why the British saw their colonial empire as a trust, a civilising mission, rather than as a resource to be exploited if profitable, and dumped if not; it explains why the British saw the Commonwealth and the Sterling Area – indeed, world affairs in general – in terms of altruistic responsibility rather than of self-interested calculation. And it was this same desire to be "nice" and "do the decent thing", rather than a resolve to improve the competitive quality of Britain's human resources, which provided the inspiration behind "New Jerusalem".
