What are the fundamental motives that explain the present rivalry of armaments in Europe, notably the Anglo-German? Each nation pleads the need for defence; but this implies that someone is likely to attack, and has therefore a presumed interest in so doing. What are the motives which each State thus fears its neighbors may obey?
They are based on the universal assumption that a nation, in order to find outlets for expanding population and increasing industry, or simply to ensure the best conditions possible for its people, is necessarily pushed to territorial expansion and the exercise of political force against others (German naval competition is assumed to be the expression of the growing need of an expanding population for a larger place in the world, a need which will find a realization in the conquest of English Colonies or trade, unless these are defended); it is assumed, therefore, that a nation's relative prosperity is broadly determined by its political power; that nations being competing units, advantage, in the last resort, goes to the possessor of preponderant military force, the weaker going to the wall, as in the other forms of the struggle for life.
