This four-session discussion guide, intended for use by teachers, students, and the community at large, explores the ethics of intervening or not intervening in conflicts abroad. Inserts provide current information on conflicts in Bosnia, Haiti, North Korea, and Somalia where U.S. military involvement is at issue, but the flexibility of the guide enables groups to include other world conflicts in discussions. The discussion sessions in the program focus on four areas: (1) reasonable grounds for using military force; (2) U.S. lives placed in harm's way; (3) U.S. involvement in the cases of the globe. Each session contains brief background material, a full range of possible positions, and discussion questions. Session 1 also provides a summary of the just-war doctrine and an annotated bibliography. Session 2 includes further information with an annotated bibliography, and session 3 presents a summary of current wars and an annotated bibliography. Session 4 presents information about who is responsible for dealing with conflicts around the globe. A description of a typical study circle follows the sessions and includes an outline for a single study circle session. Information on organizing a study circle, leading a study circle, and suggestions for participants conclude the discussion guide. (CK)
