This book investigates the factors that determine the European Union's decision-making processes and operational effectiveness in military crisis management. Katarina Engberg, a scholar in European security policy, utilizes a comparative framework to examine specific military interventions and non-interventions. By analyzing the political and strategic constraints inherent in the EU's institutional structure, the author argues that the union's military engagement is shaped by a complex interplay of member state interests and regional geopolitical realities.
