This book explores the Falklands War from an Argentinian perspective, taking into consideration three aspects. First, it introduces classified documents after the end of the thirty-year ban. Second, it highlights various conceptual, institutional, and doctrinal reforms in the Argentinian and other South American armed forces as a result of lessons learned from the Malvinas War. Third, it reflects on the war's long-term implications on Argentina’s foreign policy and society. The book offers the first comprehensive, multi-level analysis, and Argentinian scholarship on the conflict. It is based on original primary data, mainly official documentation and interviews with military officers and combatants.
