One can imagine a drawn first attack; a situation where after incredible slaughter and destruction on both sides, the belligerents would settle down to a war of gas on the frontiers and of aeroplane raids on the towns, while each side strove to manufacture enough munitions for a decisive victory. However, even a war of a few weeks or months would be enough. It would probably roll up at least as large a score of killed and maimed soldiers, of property destruction, as the late war of unblessed memory. It would probably kill many more civilians.
