“It should be needless to add that policy needs to be somewhat flexible and adaptive since war has a way of frustrating political intentions. It is a blunt instrument, and there are many reasons why cunning plans often go awry, not the least among which is the fact of an enemy with an independent will.
It would be difficult to overstate the significance of this maxim. Maxim 3 insists both that we never forget that war is about peace (see Maxim 2), and, more pointedly, that the making of peace is likely to be more difficult than the waging of war. It is a common, and somewhat understandable, error to assume that if one takes care of the fighting in an efficient manner, and the enemy is duly humbled, somehow the subsequent peace will all but take care of itself. Indeed, to go further, it is by no means unknown for professional soldiers to be less than fascinated by the political consequences of their military efforts.”
