An enemy or foe is a relativist term for an entity that is seen as forcefully adverse or threatening. The term "enemy" serves the social function of designating a particular entity as a threat.
The term is usually used within the greater context of war, to denote an opposing group and the individuals within as threats to one's own national, ethic, or political group. To individuals within the threatened group, the "enemy" concept is an amorphous personification of both a threat to one's collective social group, as well as a personal threat to oneself.
The general ideological mechanism by which particular threats are determined is called marginalization. The characterization of an individual or group as an enemy is called demonization. The propagation of demonization is a major aspect of propaganda.
An "enemy" may also be conceptual; used to describe impersonal phenomena such disease, and a host of other things. Throughout religious theology, "the Enemy" is typically reserved to represent the human tendency to do evil, often personified as a malicious deity, such as the devil or a demon.
"The enemy," as the object of social anger or repulsion, has throughout history been used as the prototypical propaganda tool to focus the fear and anxiety within a society toward a particular target. The target is often general, as with a ethnic group or race of people, or it can also be a conceptual target, as with an ideology which characterises a particular group. In some cases the concept of the enemy have morphed; whereas once racial and ethnic claims to support a call to war may later have changed to ideological and conceptual based claims.
During the Cold War, the terms "Communists" or "Reds" were believed by many in American society to mean "the enemy," and the meaning of the two terms could be extremely pejorative, depending on the political context, mood, or state of fear and agitation within the society at the time.
In Peace studies, enemies are those entities who are perceived as frustrating or preventing achievement of a goal. The enemy may not even know they are being regarded as such, since the concept is one-sided.
Thus, in order to achieve peace, one must eliminate the enemy. This can be achieved by either by:
Personal conflicts are frequently either unexamined (one's goals are not well defined) or examined only from one point of view. This means it is often possible to resolve conflict (to 'eliminate' the enemy) by redefining goals such that the frustration (not the person) is either eliminated, obvious, negotiated away, or decided upon.
