This book focuses on Post-Soviet ethnic conflicts and Russia's involvement in them. In light of its significant importance for general ethnic conflict, specifically the post-Soviet Caucasus, along with the most recent war just fought over the area from September-November 2020, this book appropriately argues that it is time to reconsider Karabakh. This project deals with the historical, social and political aspects of the Karabakh issue regarding its origins, development and the current status of the conflict subsequent to the war in the autumn of 2020. Thus, the main themes will stress these points, as well as the importance of the Karabakh issue for the future, by considering its precedents and implications for other secessionist wars. This book also explores how such wars begin and end, the international legal precedents of self-determination versus territorial integrity, its implications for post-Soviet developments and conflicts, and the latest successful weaponsdevelopments lessons from the recent war involving drones, among others such as Azerbaijan's rich oil reserves.
