How do wars end? A strategic perspective

ABSTRACT

This article gives an overview of the literature on war termination both in the fields of behaviouralism social sciences and policy-oriented strategic studies. It identifies shortcomings and problems related to both lines of research. The main problem is the undifferentiated and indiscriminate use of the term ‘war’. The article proposes a categorisation of wars that could form the basis for more thorough research on the topic of war termination.     

How do wars end? A multidisciplinary enquiry

ABSTRACT

The cessation of military confrontations rarely coincides with the end of war. Legal and political matters continue after the last shot has been fired, civilians driven from their homes try to rebuild their houses and their lives, veterans need to adapt to their new role in civil society, and the struggle to define the history and the significance of past events only begins. In recent years, in particular, the changes in the character of contemporary warfare have created uncertainties across different disciplines about how to identify and conceptualise the end of war. It is therefore an opportune moment to examine how wars end from a multidisciplinary perspective that combines enquiries into the politics of war, the laws of war and the military and intellectual history of war. This approach enables both an understanding of how ‘the end’ as a concept informs the understanding of war in international relations, in international law and in history and a reconsideration of the nature of scientific method in the field of war studies as such.     

Reconsidering the Legal Equality of Combatants

ABSTRACT

The legal equality of combatants (LEC) is a fixture of international law and just war theory. Both scholars who embrace and those who reject the moral equality of combatants seem committed to the legal equality of combatants. Their reasons usually include pragmatic worries about unjust combatants committing even more harm if they were to be simply prohibited from fighting. In this article I argue that this sweeping commitment to the legal equality of combatants is mistaken and that it is often grounded in a misunderstanding of the way international law governs behavior.
