At page 557 Hitler writes:
“Germany will either become a world power or will not continue to exist at all. But in order to become a world power, it needs that territorial magnitude which gives it the necessary importance today and assures the existence of its citizens.”

“We must take our stand on the principles already mentioned in regard to foreign policy, namely, the necessity of bringing our territorial area into just proportion with the number of our population. From the past we can learn only one lesson, and that is that the aim which is to be pursued in our political conduct must be twofold, namely: (1) the acquisition of territory as the objective of our foreign policy and (2) the establishment of a new and uniform foundation as the objective of our political activities at home, in accordance with our doctrine of nationhood.”
Now, these passages from Mein Kampf raise the question, where did Hitler expect to find the increased territory beyond the 1914 boundaries of Germany? To this Hitler’s answer is sufficiently explicit. Reviewing the history of the German Empire from 1871 to 1918, he wrote, on page 132:
“Therefore, the only possibility which Germany had of carrying a sound territorial policy into effect was that of acquiring new territory in Europe itself. Colonies cannot serve this purpose so long as they are not suited for settlement by Europeans on a large scale. In the nineteenth century it was no longer possible to acquire such colonies by peaceful means. Therefore, any attempt at such colonial expansion would have meant an enormous military struggle. Consequently it would have been more practical to undertake that military struggle for new territory in Europe, rather than to wage war for the acquisition of possessions abroad.
“Such a decision naturally demanded that the nation’s undivided energies should be devoted to it. A policy of that kind, which requires for its fulfillment every ounce of available energy on the part of everybody concerned, cannot be carried into effect by half measures or in a hesitant manner. The political leadership of the German Empire should then have been directed exclusively to this goal. No political step should have been taken in response to other considerations than this task and the means of accomplishing it. Germany should have been alive to the fact that such a goal could have been reached only by war, and the prospect of war should have been faced with calm and collected determination. The whole system of alliances should have been envisaged and valued from that standpoint.
“If new territory were to be acquired in Europe it must have been mainly at Russia’s cost, and once again the new German Empire should have set out on its march along the same road as was formerly trodden by the Teutonic Knights, this time to acquire soil for the German plough by means of the German sword and thus provide the nation with its daily bread.”
To this program of expansion in the East Hitler returns again, at the end of Mein Kampf. After discussing the insufficiency of Germany’s pre-war frontiers, he again points the path to the East and declares that the Drang nach Osten, the drive to the East, must be resumed:
“Therefore we National Socialists have purposely drawn a line through the line of conduct followed by pre-war Germany in foreign policy. We put an end to the perpetual Germanic march towards the South and West of Europe and turn our eyes towards the lands of the East. We finally put a stop to the colonial and trade policy of pre-war times and pass over to the territorial policy of the future. But when we speak of new territory in Europe today we must principally think of Russia and the border states subject to her.”
