The conditions of modern war are bound to be the cause of huge expenditure. First of all, military stores must be drawn by every country from its own resources. Artillery, rifles, and ammunition are all far more costly than they used to be, and the amount of ammunition consumed in a modern European campaign will be prodigious. The vastness of armies, and the deadliness of modern weapons, will add immensely to the requirements of the sick and wounded. The demand for provisions must vastly increase, and the increase will be followed by a great rise in prices. That an immense army cannot exist on the resources of an enemy's territory is plain, especially when the slowness of advance in a struggle for fortified positions is taken into account. Communications by sea will be interrupted at the very outbreak of war. In this respect England is in incomparably the worst position. There are serious reasons for doubting the proposition that a future war would be short. Thanks to railways, the period of preparatory operations would be considerably shortened; but in marches, manoeuvres, and battles railways can be employed only in very rare cases, and as lines of operation they cannot serve. The question naturally arises: Will it be possible to raise for war purposes revenues vastly exceeding the normal revenues of European states? And what results must we expect from such extraordinary tension? A careful and thorough inquiry shows that no great power is economically capable of bearing the strain of a great war. Russia has in this respect an important advantage in that her workers, who are her fighters, are mostly agricultural; the members of their families can continue their labours when the summons to war is issued. But, on the other hand, the Russian rural population is extremely poor, and her resources would quickly be exhausted. As for England, the interruption of maritime communications would affect disastrously, if not fatally, the industries of the country and the feeding of her population. England depends to so great an extent upon imported wheat that a war would threaten the whole population with famine. The very large industrial portion of the German community would be hit most severely. The stoppage of work and the rise in prices would cause intense suffering and violent discontent. Although France survived the economic strain of the war of 1870, it does not follow that she could endure the far greater strain of a campaign under the new conditions. Her industrial population, like that of Germany, would be ruined, and the resulting misery might well lead to revolution. A great European war, then, would bring about the economic prostration of every nation engaged in it, and would be a cause of violent danger to the fabric of society.
