Contributor(s): Dr Louise Arimatsu, Dr Robin Dunford, Dr Rachel Julian, Dr Michael Neu | What factors promote peace and what actions are justified to achieve it? Join us as we discuss the history, ethics, and politics of peace. Peace is highly valued, but how is it achieved? Why are some periods in world history relatively peaceful compared to others? What can we, as ordinary citizens, do to promote peace? Is pacifism a justified response to war? What are we justified in doing to ensure peace?
