In the preceding chapter we have said that, under the expression “overthrow of the enemy,” we understand the real absolute aim of the “act of war;” now we shall see what remains to be done when the conditions under which this object might be attained do not exist.
These conditions presuppose a great physical or moral superiority, or a great spirit of enterprise, an innate propensity to extreme hazards. Now where all this is not forthcoming, the aim in the act of war can only be of two kinds; either the conquest of some small or moderate portion of the enemy’s country, or the defence of our own until better times; this last is the usual case in defensive war.
Whether the one or the other of these aims is of the right kind, can always be settled by calling to mind the expression used in reference to the last. The waiting till more favourable times implies that we have reason to expect such times hereafter, and this waiting for, that is, defensive war, is always based on this prospect; on the other hand, offensive war, that is, the taking advantage of the present moment, is always commanded when the future holds out a better prospect, not to ourselves, but to our adversary.
The third case, which is probably the most common, is when neither party has anything definite to look for from the future, when therefore it furnishes no motive for decision. In this case, the offensive war is plainly imperative upon him who is politically the aggressor, that is, who has the
