Inefficient nations were always conquered sooner or later, and the struggle for efficiency was inimical to illusions. War was a sure safeguard of sanity, and so far as the ruling classes were concerned it was probably the most important of all safeguards. While wars could be won or lost, no ruling class could be completely irresponsible. But when war becomes literally continuous, it also ceases to be dangerous. When war is continuous there is no such thing as military necessity.
Technical progress can cease and the most palpable facts can be denied or disregarded.
As we have seen, researches that could be called scientific are still carried out for the purposes of war, but they are essentially a kind of daydreaming, and their failure to show results is not important. Efficiency, even military efficiency, is no longer needed. The war, therefore, if we judge it by the standards of previous wars, is merely an imposture. It is like the battles between certain ruminant animals whose horns are set at such an angle that they are incapable of hurting one another. But though it is unreal it is not meaningless.
