Latin America has long aspired for an interstate system based on the principles of nonintervention and adherence to international law. Over time, the region has become increasingly free of war, and interstate disputes are frequently settled via diplomacy or by international courts. But it has achieved a largely “negative” peace as peaceful relations in the region are neither the result of nor have produced deeper commercial integration, effective regional organizations, or epistemic security communities. This chapter examines realist, liberal, and constructivist explanations to explain the sources of peace and peaceful change in Latin America, as well as how structural changes in the international system have affected the region. In particular, it analyzes how Latin America’s relative weakness in terms of material capabilities has led it to rely on diplomacy, “soft balancing,” and norms entrepreneurship in international law to secure its interest in a progressively more peaceful and rule-bound international order.
