Psychological warfare is a tactic involving the use of propaganda or similar methods to demoralize the enemy in an attempt to ensure victory, possibly without even having to use physical violence. This form of warfare has matured over time from the intimidating military maneuvers of the Mongols to the spreading of leaflets by the United States over Japan in World War II and later over Afghanistan. New technologies such as the radio, television, and the internet have helped carve the face of modern psychological warfare, ever creating new ways to reach the opposition. As long as war exists, we can expect new forms of psychological warfare to be formulated in attempts to achieve victory at less cost to one's own side. Ultimately, however, the greatest victory will be a world in which all methods of war are unnecessary and human beings can resolve their differences peacefully.
Psychological warfare is a tactic used to demoralize one’s opponent in an attempt to ensure victory in battle. By feeding into the pre-existing fears of the enemy, psychological warfare causes terror, encourages opposing forces to retreat, and can end a battle before it begins. Alternatively, it may involve an attempt to sway the enemy's viewpoint towards one's own position, also leading him to abandon the fight. Such methods often include the use of propaganda, and may be supported by military, economic, or political means.
Civilization refers to a complex human society, in which people live in groups of settled dwellings comprising cities. Early civilizations developed in many parts of the world, primarily where there was adequate water available. The causes of the growth and decline of civilizations, and their expansion to a potential world society, are complex. However, civilizations require not only external advances to prosper, but also the maintenance and development of good social and ethical relationships usually grounded in religious and spiritual norms.
