Despite the millennial hopes for peace wishfully harboured by so many, the opening years of the twenty-first century have seen the morality of war remain urgently central to political argument around the world. The just war tradition has provided one of the most beguiling frameworks for the question of when it is right to go to war, and how war ought to be conducted. However, criticisms of it are as old as the tradition itself and many now claim that the nature of contemporary warfare has made it truly redundant. This book addresses the criticisms and explores new angles to just war thinking, analysing its practical adequacy in the face of modern-day realities. It is written with the aim of stimulating debate, recasting or revivifying critical reservations, but also powerfully demonstrating how just war theory cannot be ignored if we take seriously the moral questions warfare forces upon us.
