Are today's wars different from earlier wars? Or do we need a different ethics for old and new wars alike? Unlike most books on the morality of war, this book rejects the 'just war' tradition, proposing a virtue ethics of war to take its place. Like torture, war cannot be justified. David Chan asks and answers the question: 'If war is a very great evil, would a leader with courage, justice, compassion, and all the other moral virtues ever choose to fight a war?' A 'philosophy of co-existence' is proposed which is much more restrictive than just war theory but not pacifist. War can be correctly chosen by a virtuous leader only in rare 'supreme emergencies' when faced with enemies as evil as Hitler. This virtue ethics approach to war is used to find new answers to difficult issues such as humanitarian intervention, terrorism and weapons of mass destruction.
