Unfortunately Germany was not a democratic and unmilitary state like the other industrial giant of the world, the United States. She was a militarymonarchy, just as France had been in her own days of greatness. Like France, Germany had been united by the sword. She inherited the martial traditions and myths of Prussia, and she also possessed the most efficient, best equipped and incomparably the most powerful army in the world. Moreover, Germany was geographically so placed as to command Europe from its heartland; able to expand diplomatically, economically and, if necessary, militarily to the east or the west. The advantage of this central position was enhanced by a superb strategic railway system planned by the Prussian general staff. And, lastly, all Germany's powers and resources were rendered the more effective by the German talent for organisation.
