The European states, and above all Germany (newly united in 1871), therefore entered the second Industrial Revolution, that of science-based industri… - Correlli Barnett

The importance of war and military institutions has been generally neglected in British historical writing, whose tone has been set by the Whig and liberal emphasis on peaceful constitutional progress. In this liberal view war appears as an aberration, an interruption of a "natural" condition of peace: almost as a form of delinquency unworthy of intellectual attention. The liberal, pacifistic view of history can only be maintained by resolute aversion of the gaze from the facts. For conflict between tribal or social groups and nations constitutes the essential human condition in the absence of a world-state with a monopoly of force. The relations between nation states have always been those of a struggle for advantage and domination, where friendships may indeed burgeon while interests temporarily coincide, but then again languish when those interests diverge. Peace and war in history flow continually in and out of each other, alternative aspects of the single phenomenon of the struggle for power. It is false and unrealistic therefore to divide policy between hard-and-fast categories of "peace" and "war". Policy may shade all the way from trade and diplomatic rivalry through indirect conflict and limited war to total war; the distinctions are of degree, not of kind

The truth is that the Labour Government, advised by its resident economic pundits, freely chose not to make the re-equipping of Britain as an industrial society the Schwerpunkt of her use of Marshall Aid. Instead, the Government saw Marshall Aid (like the American loan of 1945) primarily as a wad of greenbacks stuffed by a kindly Uncle Sam into the breeches pocket of a nearly bankrupt John Bull who, though diligently seeking future solvency, nevertheless still wished in the meantime to go on playing the squire, beneficent to his family and the poor, and grand among the neighbours.

It is Northern Ireland that provides the classic contemporary demonstration of Clausewitzian principles in action. In 1974 the Ulster Protestants rejected powersharing under the 1973 Sunningdale agreement to the point of launching a general strike which the British army warned the British government it could not handle. The government thereupon abandoned the project. But in 1998 the majority of Unionist political parties and at least half the Unionist electorate have come to accept power-sharing under the deal brokered by Mo Mowlam. Wherein lies the essential difference between 1973–74 and 1998? It lies in the profound yearning on the island of Ireland and on the British mainland (including Whitehall and Westminster) for "peace" after the intervening 25 years of unrelenting "war" on the part of the IRA, years of violence of the most extreme kind intended (to quote Clausewitz) "to compel our opponent to fulfil our will". Thus all the talk of compromise and reconciliation in Northern Ireland is just so much small-l liberal blather disguising the Clausewitzian reality that by their "continuation of politics by other means" the IRA have indeed compelled their opponents to fulfil their will.
