There are of course the neo-Puginites or neo-Morrisites who like to think of Britain as leading the world into a post-industrial phase where this for… - Correlli Barnett

On the basis of legal advice sketchy enough to be put on one side of a sheet of A4, and from a single lawyer who was also a cabinet minister, Blair finally took Britain to war against a country which posed no threat at all to British interests, let alone to the United Kingdom itself.
There can be no sterner test of a national leader's soundness of judgement than when he has to decide between peace and war. And there can be no sterner test of his probity than his choice of the means of persuading his countrymen to back him. Both these tests Tony Blair has unquestionably failed. As a result, he stands convicted of being wholly unworthy of our trust. This is the central fact of this election, and we should vote accordingly.

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.

With the outbreak of war in 1914 the internationalists in the Liberal and Labour parties, already losing credit, seemed to go into intellectual bankruptcy. The moral law was demonstrated to carry less weight than a military railway timetable. A solemn treaty was shown to have the protective power of a magic charm. The natural harmony of human interests was disproved by the spectacle of great nations at each other's throats. The pacifying and unifying effects of modern science and communications were ridiculed by the convenience with which railways launched into battle millions of men equipped with artillery and machine-guns. The liberal-evangelical faith in love, reason and the brotherhood of man was cruelly mocked by the ferocious hatreds bayed by the mobs in the great cities of Europe.
