A statesman's responsibility to act morally while remaining politically fastidious is a primary difficulty in international relations. Theories that provide definitive guidance for political morality are often viewed with suspicion and considered unrealistic. Coll, in opposition to this dismissive approach, sees in the Christian worldview three core values that can be used to discern moral political actions: the importance of history, the ubiquity of tragedy, and practical wisdom. Coll explicates the Christian tradition that informs each of these values and considers their pertinence in international relations today. He goes on to extract some general prescriptions for foreign policy, showing that these core values speak to military action, immigration, foreign aid, and the environment.
