Expenditure upon preparation for war falls, roughly, into two classes; there is expenditure upon things that have a diminishing value, things that grow old-fashioned and wear out, such as fortifications, ships, guns, and ammunition, and expenditure upon things that have a permanent and even growing value, such as organised technical research, military and naval experiment, and the education and increase of a highly trained class of war experts. I want to suggest that we are spending too much money in the former and not enough in the latter direction. We are buying enormous quantities of stuff that will be old iron in twenty years’ time, and we are starving ourselves of that which cannot be bought or made in a hurry, and upon which the strength of nations ultimately rests altogether; we are failing to get and maintain a sufficiency of highly educated and developed men inspired by a tradition of service and efficiency. No doubt we must be armed to-day, but every penny we divert from men-making and knowledge-making to armament beyond the margin of bare safety is a sacrifice of the future to the present. Every penny we divert from national wealth-making to national weapons means so much less in resources, so much more strain in the years ahead. But a great system of laboratories and experimental stations, a systematic, industrious increase of men of the officer-aviator type, of the research student type, of the engineer type, of the naval-officer type, of the skilled sergeant-instructor type, a methodical development of a common sentiment and a common zeal among such a body of men, is an added strength that grows greater from the moment you call it into being. In our schools and military and naval colleges lies the proper field for expenditure upon preparation for our ultimate triumph in war. All other war preparation is temporary but that. This would be obvious in any case, but what makes insistence upon it peculiarly urgent is the manifestly temporary nature of the present European situation and the fact that within quite a small number of years our war front will be turned in a direction quite other than that to which it faces now. For a decade and more all Western Europe has been threatened by German truculence; the German, inflamed by the victories of 1870 and 1871, has poured out his energy in preparation for war by sea and land, and it has been the difficult task of France and England to keep the peace with him. The German has been the provocator and leader of all modern armaments. But that is not going on. It is already more than half over. If we can avert war with Germany for twenty years, we shall never have to fight Germany. In twenty years’ time we shall be talking no more of sending troops to fight side by side on the frontier of France; we shall be talking of sending troops to fight side by side with French and Germans on the frontiers of Poland.
