Is war ever a just way to resolve conflict? Diana Francis argues that it is not. With passion and eloquence, she mounts a head-on challenge to the belief that war as an institution is either necessary or effective for good. Refuting the notion that human nature condemns us to perpetual carnage, she argues that we can change the ways we think and the systems we live by. In a tightly reasoned discussion of the ethics of war and peace she asserts that war is a gross denial of the core values on which peace depends, and that the Just War Theory has failed and deceived us. The book explores alternative ways of confronting aggression and injustice, showing that these are neglected but well proven. Francis argues that our security can be enhanced by recognition of our shared responsibility for each other and our planet. Practial solutions require a new level of participation in public affairs. Recent events have shown that this is possible. Francis outlines the steps we must take to bring about the radical shift so urgently needed.
