This book examines diplomatic influence and collective decision-making within the transatlantic security regime, focusing on the four major states of NATO : France, Germany, the UK, and the United States. Two cases of post-Cold War transatlantic military intevention are examined in which regime member states sought to develop and adopt a single, collective policy on the use of military force outside of NATO's territorial area of operations : Bosnia-Herzegovina and Kosovo. The question is, what conditions or factors increase or decrease the likelihood of the member states of the transatlantic security regime adopting a common, collective policy with regard to military intervention in a given case? The author ansers that question by testing the roles of six alternative rival explanations : power, threat perception, international institutions, risk analysis, perceptual lenses, and domestic political pressures.

The politics of transatlantic military intervention -- About the rival variables -- Origins of the crisis : the breakup of Yugoslavia -- Bosnia-Herzegovina -- Kosovo.
