Regional collective security in Europe: Past patterns and future prospects

Abstract

NATO's entry into the Balkan war raised salient questions about the alliance's broader mission and, more generally, about Europe's security architecture. This article confronts these questions by revisiting the debate about collective defense versus collective security as organizing principles for alliances. NATO is viewed as serving a hybrid role of promoting collective defense and regional collective security. This latter, under‐valued function relates to NATO's role in promoting internal cohesion among its members and is crucial to understanding the alliance's evolution and its persistance long after the Cold War.
