Psychological operations include psychological warfare and encompass those political, military, economic, and ideological actions planned and conducted to create in neutral, friendly, and nonhostile foreign groups the emotions, attitudes, or behavior to support the achievement of national objectives.
Psychological warfare is the planned use of propaganda and other psychological actions to influence the opinions, emotions, attitudes, and behavior of hostile foreign groups in such a way as to support the achievement of national objectives.
Society is an enduring and cooperative social group whose members have developed organized patterns of relationships, traditions, institutions, and collective activities and interests. Societies may be considered to be relatively independent human groupings that have their own territory, contain persons of all ages and both sexes, and maintain their unique respective lifestyle (culture). The American people, for instance, have formed lasting and cooperative social groupings which demonstrate organized patterns of behavior such as religious, educational, and political systems.
