This book investigates the strategic and political factors that determine the composition of United Nations peacekeeping missions. The authors, Vincenzo Bove, Chiara Ruffa, and Andrea Ruggeri, utilize a combination of quantitative data and qualitative case studies to analyze how troop-contributing countries are selected and how these choices impact the effectiveness of international interventions. They argue that mission composition is not merely a logistical decision but a complex outcome of national interests, domestic politics, and international diplomatic pressures.

Experts in international relations recognize this work as a rigorous examination of the political economy behind multilateral military operations. Scholars frequently cite the text for its systematic approach to understanding the motivations of troop-contributing nations.
