And one of the most extraordinary features of this whole question is that the absolute demonstration of the falsity of this idea, the complete exposure of the illusion which gives it birth, is neither abstruse nor difficult. This demonstration does not repose upon any elaborately constructed theorem, but upon the simple exposition of the political facts of Europe as they exist to-day. These facts, which are incontrovertible, and which I shall elaborate presently, may be summed up in a few simple propositions stated thus: 1. An extent of devastation, even approximating to that which Mr. Harrison foreshadows as the result of the conquest of Great Britain, could only be inflicted by an invader as a means of punishment costly to himself, or as the result of an unselfish and expensive desire to inflict misery for the mere joy of inflicting it. Since trade depends upon the existence of natural wealth and a population capable of working it, an invader cannot "utterly destroy it," except by destroying the population, which is not practicable. If he could destroy the population he would thereby destroy his own market, actual or potential, which would be commercially suicidal.[6] 2. If an invasion of Great Britain by Germany did involve, as Mr. Harrison and those who think with him say it would, the "total collapse of the Empire, our trade, and the means of feeding forty millions in these islands ... the disturbance of capital and destruction of credit," German capital would also be disturbed, because of the internationalization and delicate interdependence of our credit-built finance and industry, and German credit would also collapse, and the only means of restoring it would be for Germany to put an end to the chaos in England by putting an end to the condition which had produced it. Moreover, because of this delicate interdependence of our credit-built finance, the confiscation by an invader of private property, whether stocks, shares, ships, mines, or anything more valuable than jewellery or furniture--anything, in short, which is bound up with the economic life of the people--would so react upon the finance of the invader's country as to make the damage to the invader resulting from the confiscation exceed in value the property confiscated. So that Germany's success in conquest would be a demonstration of the complete economic futility of conquest. 3. For allied reasons, in our day the exaction of tribute from a conquered people has become an economic impossibility; the exaction of a large indemnity so costly directly and indirectly as to be an extremely disadvantageous financial operation.
