Political violence in the form of wars, insurgencies, terrorism, and violent rebellion constitutes a major human challenge. C. A. J. Coady brings a philosophical and ethical perspective as he places the problems of war and political violence in the frame of reflective ethics. Coady re-examines a range of urgent problems pertinent to political violence against the background of a contemporary approach to just war thinking. The problems examined include: the right to make war and conduct war, terrorism, revolution, humanitarianism, mercenary warriors, the ideal of peace and the right way to end war. Coady attempts to vindicate the contemporary relevance of the just war tradition to current problems without applying the tradition in a merely mechanical or uncritical fashion.
