With regard to Blunt, we should remember that the 1920s and 1930s marked a high tide of romantic idealism, or high-minded priggishness, among the pub… - Correlli Barnett

The deal between the French and the Israelis was struck in Paris on 1 October 1956. An eighteenth-century British cabinet would not have hesitated to join in... In contrast, Eden's cabinet was riven by moral squeamishness; so too were the house prefects of the Foreign Office.
The irony lay in that the political and psychological shackles which the morally squeamish now found so uncomfortable had been forged by themselves. It was they and their predecessors who since 1918 had brought about the prevailing climate of opinion in which a state's naked pursuit of self-interest, if necessary by armed diplomacy, if necessary by war, was deemed a sin, even a crime. In furtherance of their romantic vision that a "world community" ruled by law could, and would, replace the existing world arena of group struggle, they and their predecessors had first created the League of Nations and its futile Covenant, and then, after the Second World War, the United Nations Organisation and its Charter. Since this document outlawed war except in clear cases of self-defence, it now supplied an peculiarly uncomfortable shackle for Britain, for here she was, a Permanent Member of the UN Security Council and yet secretly plotting to revert to realpolitik.

[L]ate-Victorian Oxbridge positively harmed the prospects of the British economy by completing the work of the public schools in turning out a governing élite imbued with Newmanian ideals of a liberal education in humanistic culture; an élite which both generally and in particular cases...neglected or even hamstrung developments in technical education.

It was the grimmest legacy ever inherited by an English Prime Minister; a situation probably beyond remedy even by statesmanship of the most far-sighted and cool-headed genius. The first and urgent question, the question which filled the minds of War Cabinet and nation alike, was whether the United Kingdom itself could for long survive in the face of the immensely powerful forces, elated with victory, which were gathering just across the narrow seas; or whether the swastika would fly above the Houses of Parliament and on the church towers of the English countryside, and the boots of a foreign conqueror stand on the soil of England for the first time since the Middle Ages.
It was a time for former moralising internationalists either to repent, or skulk behind the armed forces they had sought so devotedly to dismantle. For this was the hour, an hour too long delayed, when England returned to herself; when English policy once again spoke in broadsides instead of sermons. To the world's astonishment, the nation which had allowed itself to be represented by – which had even seen itself mirrored in – men like Baldwin, MacDonald, Henderson, Simon, Chamberlain, reverted of a sudden to its eighteenth-century character, hard as a cannon.
