This book brings together contributions from scholars of various social science disciplines on three themes that appeared significant for the study of the phenomenon of conflict and conflict resolution. The first theme is centered on the new aspects of war in the twenty-first century where asymmetric warfare has changed many rules of the game, imposing a profound transformation on the military, not only tactical, but also structural, preparatory, mental and ideological.The second theme regards the delicate relations between the armed forces and societies. The ever-greater technicality of military operations and their lower comprehensibility to the broad public as a result, together with increased sensitivity in many countries in regard to the use of violence and death, have created social situations and problems that deserve to be investigated. The third theme, building and sustaining peace, operationalizes different types and levels of violence and conflict. It assesses ongoing efforts, for instance, governments trying to contain or diffuse conflict, businesses and national service schemes building peaceful civil spheres, and the efforts of organized groups to claim, shape, and extend the spheres of life that are free of conflict.
