Book excerpt: Coker (international relations, London School of Economics and Political Science, UK) puts a new spin on war by considering it as a changeable phenomenon that varies through time and place. The shift of war from an event that drew physically and emotionally on a nation's people to one that is seen with detachment as foreign policy is the book's major premise. Coker considers numerous wars, both ancient and modern (including the recent conflicts in Somalia and Afghanistan), and also considers the impact of computers and the possibility of cyber-war.
