Enemy
An enemy or foe is a relativist term for an entity that is forcefully adverse or threatening. The term is usually used in the context of war, to denote the opposing group and the individuals within. The term "enemy" serves the social function of designating a particular entity as a threat, and the "most feared enemy" status reserved for those who pose the greatest mortal threat.
The general ideological mechanism by which particular threats are determined is called marginalization. (Mechanisms which assert a unilateral amnesty for particular individuals and groups as being "enemies" is protectionism.) The characterization of an individual or group as an enemy is called demonization. The propagation of demonization is called 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 tendecy to do evil, often personified as a malicious deity, such as the devil or a demon.
Terms
"Enemy" is a strong word, evoking associations of hate, violence, battle and war. The opposite of an enemy is a friend or ally; the state of being or having an enemy is enmity. But in general, "the enemy" is a bit too militaristic a term to use in polite society, and informal substitutes are moreoften used. Often the terms become pejoratives in the context that they are used. In any case, the designation of an "enemy" exists solely to denote the status of a people or group as a threat, and to propagate this within the local context.
"The enemy," as the object of social anger or repulsion, has througout 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 group or race of people, or conceptual, as with an idea which marks a particular group. In some cases the concept of the enemy has developed with society; wheras once racial and ethnic claims to support a call to war, later became ideological and conceptual.
In the United States, the current "War on Terrorism" is widely understood to be the replacement for the Cold War against "Communism." Thus the enemy term "communist" has largely given way to the newer "terrorist," and the threats of nuclear annihilation and "communist expansion" gave way to "terrorism" and Islamic fundamentalism.
During the Cold War, the term "Communist" or "Reds" were broadly understood in American society to mean "the enemy," and often this meaning was extremely pejorative, depending on the mood or state of fear and agitation within the society.
