The book is about assessing the effectiveness of a traditional UN Peace Operation. The book first goes on to develop a conceptual framework for the evaluation of UN peace operations and apply that to assess the performance of a traditional UN Peace Operation with UNIFIL as a case study. The author relies on empirical data, supported by perceptions and practical experiences of peacekeepers and 'subject matter experts' at both the operational and tactical levels using a mixed method of qualitative and quantitative analysis. The author proves that UNIFIL can be assessed to be a satisfactorily successful UN Peace Operation. He ends the book with a few major takeaways and offers actionable recommendations to the practitioners of peacekeeping and for future reform of UN peace operations. This book is the first of its kind by a former Indian peacekeeper who holds a PhD from Tilburg University, the Netherland.
