Pp. 61-80.Understanding peace between nations requires a combination of theories from the schools of international relations and social psychology. The idea of stable peace is a situation where different parties enjoy enough harmony that the possibility of war is not really a factor. Bar-Siman-Tov identifies three conditions for stable peace, including mutual satisfaction, common and cooperative structural-institutional conditions, and learning or cognitive change. Meanwhile, reconciliation signifies the transformation from hostility to harmonious relations, and requires cognitive and emotional changes on both sides. The author examines dialectics between stable peace and reconciliation, suggesting a conceptual framework for combining the complementary ideas.
