Why War? The Nature of War in the Ages of Tradition, Modernity and Post-modernity

An investigation and analysis of different periods of war and also its nature and role among different societies is of paramount importance to sociologists and researchers of political sciences. The present research, in addition to conducting a study of the history of war and the changes it experienced in its nature among traditional, modern and post-modern societies, will make an assessment of a society's structural and cognitive changes; it will also try to delineate the role of war in shaping the identity of a society. The author chiefly aims at proving this important point that "We are still living in militaristic societies".
In other words and contrary to the quite optimistic approach of modern age in doing away with war from the lives of people, we can constantly witness the more destructive forms of war and negative consequences that it leaves on world environment. This danger is so huge that it threatens the human race in the post-modern world. This research work will resort to various statistics and examples in objectifying the hypotheses it raised.
