[T]he essential and constant factor common to all three national academies [in Britain, France and America] is the indoctrination with tradition: pot… - Correlli Barnett

Britain therefore entered the twentieth century an ill-educated, one might say ignorant, nation compared with its rivals; and particularly weak in those key areas of education on which industrial success depends. We see in these failures the combined baneful effects of liberal laissez-faire's reluctance to embark on large-scale state education at all levels, the "practical man"s' scorn for technical education, and a public-school-educated governing élite's lack of comprehension that Britain stood or fell by her industrial capability.

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.

That Clausewitz lives, and will live, is equally shown in such cases as the former Yugoslavia, where Nato has simply frozen a war which will certainly break out again if and when the intervention forces leave; or Israel–Palestine, where the political relations between Jew and Arab reflect the military outcome of past wars, where the conflict of interest is essentially irreconcilable, and where therefore policy and violence will continue to go hand in hand.
What may therefore be safely predicted is that over the next 170 years the world will continue to be an arena of complex rivalries and direct collisions of interest rather than a "world order" or a "world community", and that human groups engaged in such rivalries will from time to time resort to force as an instrument of their politics. What weapons will be then available, and what tactics will consequently be employed, only a fool would pretend to guess. It will be remarked that so far I have not mentioned the United Nations Organisation, that expensive figment of liberal wishful thinking. I have done so now.
