But, above all, she put her trust in a vast political combination which she had laboriously prepared during the years preceding the great conflict: the combination which we have learned to call Mittel-Europa. None of us realised to how great an extent this plan had been put in operation before the war began. Briefly it depended on the possibility of obtaining an intimate union with the Austro-Hungarian Empire, a control over the Turkish Empire, and a sufficient influence or control among the little Balkan states to ensure through communication. If the scheme could be carried out in full, it would involve the creation of a practically continuous empire stretching from the North Sea to the Persian Gulf, and embracing a total population of over 150,000,000. This would be a dominion worth acquiring for its own sake, since it would put Germany on a level with her rivals. But it would have the further advantage that it would hold a central position in relation to the other world-powers, corresponding to Germany’s central position in relation to the other nation-states of Europe. Russia could be struck at along the whole length of her western and south-western frontier; the British Empire could be threatened in Egypt, the centre of its ocean lines of communication, and also from the Persian Gulf in the direction of India; the French Empire could be struck at the heart, in its European centre; and all without seriously laying open the attacking powers to the invasion of sea-power.
