The power of the State outside its own borders is in the main derived from war or the threat of war. Some power is derived from the ability to persuade its citizens to lend money or not to lend it, but this is unimportant in comparison with the power derived from armies and navies. The external activity of the State—with exceptions so rare as to be negligible—is selfish. Sometimes selfishness is mitigated by the need of retaining the goodwill of other States, but this only modifies the methods employed, not the ends pursued. The ends pursued, apart from mere defense against other States, are, on the one hand, opportunities for successful exploitation of weak or uncivilized countries, on the other hand, power and prestige, which are considered more glorious and less material than money. In pursuit of these objects, no State hesitates to put to death innumerable foreigners whose happiness is not compatible with exploitation or subjection, or to devastate territories into which it is thought necessary to strike terror. Apart from the present war, such acts have been performed within the last twenty years by many minor States and by all the Great Powers[7] except Austria; and in the case of Austria only the opportunity, not the will, was lacking. Why do men acquiesce in the power of the State? There are many reasons, some traditional, some very present and pressing. The traditional reason for obedience to the State is personal loyalty to the sovereign. European States grew up under the feudal system, and were originally the several territories owned by feudal chiefs. But this source of obedience has decayed, and probably now counts for little except in Japan, and to a lesser extent in Russia.
