The attempt to give international society a minimum of government and order through the establishment of a League of Nations has proved only moderately successful. It is true that states have begun to play politics in Geneva, but they have not ceased the older and grimmer struggle for power in the world at large. The state is still today, as far as its international relations are concerned, primarily a military organization. Its specific aims in its struggle for power may be many, but among them the geographic objectives, the attainment of which will increase the state's relative military strength, are the oldest and the most persistent.
There are several types of geographic objectives, but in this analysis we shall concern ourselves with the strategic geographic objectives of foreign policy. Before we attempt to analyze these specific objectives, however, it is essential to consider briefly the phenomenon of expansion as such, which may be defined as a mere advancement of frontier in contrast to the conquest of a particular bit of territory for strategic reasons.
