Since the term ‘strategy’ is now generally used to describe the use of available resources to gain any objective, from winning at bridge to selling soap, it is necessary to make clear that, in this paper, I shall use it in the traditional sense only: that is, as meaning the art of the strategon, or military commander. ‘The strategic approach’ is thus one which takes account of the part which is played by force, or the threat of force, in the international system. It is descriptive in so far as it analyses the extent to which political units have the capacity to use or to threaten the use of armed force to impose their will on other units; whether to compel them to dos ome things, to deter them from doing others, or if need be to destroy them as independent communities altogether. It is prescriptive in so far as it recommends policies which will enable such units to operate in an international system which is subject to such conditions and constraints.
