The Implementation of National Policy. Organized government exists for the purpose of bringing into systematic union the individuals of a State for the attainment of common ends. The primary national objective ([page 3]) is the ensurance of envisaged prosperity and of essential security for the social system which is the fundamental basis of the community. Whatever the form of government, the power and authority of the State are vested in an individual, or in a grouping of individuals, whose voice is the voice of the State. In the prosecution of the chief aim of organized government, the State crystallizes the many conflicting desires and views of its people into policies, internal and external. Each policy is a method of procedure for attaining one or more national objectives.

Internal policies are rendered effective by enforcement of the laws of the State.

External policies, to become effective, require recognition by other States, tacitly or by agreement. When there is conflict between the policies of one State and those of another, peaceful means of settlement are usually sought.

If peaceful (diplomatic) means fail to settle the point at issue, the State abandons the policy in question, defers action to enforce it, or adopts stronger measures. Such measures may take the form of psychological, political, or economic pressure. They may even include the threat to employ armed force before actually resorting to the imposition of physical violence. During actual hostilities, also, every means of pressure known to man, in addition to physical violence, may be employed.

Whether the use of armed force to impose or to resist the imposition of policy constitutes a legal state of war is a political question which does not affect the tasks the armed forces may be called on to perform. War, therefore, is to be understood herein as any condition in which one State employs physical violence against another, or against an organized part of itself which may be in rebellion.

By agreement among nations, effort has been made to discountenance aggressive warfare. The distinction between aggression and self-defense is, however, not a matter of agreement. War is still employed as an instrument of national policy. No nation has, as yet, manifested willingness to relinquish the right to employ armed force in resisting aggression, nor the right to decide what constitutes self-defense. States still maintain and employ armed forces as a means of promoting and expanding, as well as of defending, their welfare and interests.

The Primary Function of the Armed Forces. Whether war is an ethical institution is not a matter within the purview of the armed forces. Their primary function is, when called upon to do so, to support and, within the sphere of military effort, to enforce the policy of the State. The performance of this function constitutes the chief reason for their existence.

The fundamental objective of the armed forces is, therefore, the reduction of the opposing will to resist. It is attained through the use of actual physical violence or the threat thereof ([page 7]). This fact constitutes the underlying motive of every military plan, whether for the conduct of a minor or contributory operation, or for the prosecution of a major campaign. The final outcome is dependent on ability to isolate, occupy, or otherwise control the territory of the enemy, for land is the natural habitat of man ([page 46]). Since opposition is to be expected, the military problem is primarily concerned with the application of power—mental, moral, and physical—in overcoming resistance, or in exerting effort to resist.

The application of power implies effort, i.e., the exertion of strength. The mental, moral, and physical power at the disposal of the armed forces depends on the effort which can be exerted by the human and material components of their fighting strength.

The skillful employment of fighting strength, as a weapon more effective than the enemy's under a given set of circumstances, is the goal toward which the armed forces direct their effort. The elements of the material component—arms, ammunition, and other equipment—are indispensable. They are impotent, however, without the direction and energy supplied by the human component, its moral and mental elements nicely balanced and judiciously compounded with physical fitness. A true concept of the art of war will insist that the necessity for the achievement of a high standard of technical and administrative skill not be permitted to outweigh the need for maximum development of other mental attainments, and of the moral components of fighting strength.
