The revolutions of 1989-90 in Eastern Europe and the current crisis in the Middle East raise a whole new series of questions about national security and how they can be defined and implemented. But there are a number of basic philosophical and political issues which remain constant at a level deepr than tactical considerations. The essays in this volume bring together concerned philosphers, political scientists, Christian ethicists, and policymakers who discuss the fundament and perduing questions of pacifism, war, intervention, and political negotiation. What, for instance, do the churches have to contribute to the quest for peace other than exhortation? Who defines our "national interests" and what does it have to do with a deeper "national purpose?" How can we come to consider the question of intervention in other than strictly unilateral terms? These are the kinds of questions that require considerable reflection as well as political savvy.
