Jus Post Bellum and Counterinsurgency

Abstract

The United States’ continuing engagements in Iraq and Afghanistan have focused reflection on how best to wage counterinsurgency, recognizing that the blurred lines between combatants and noncombatants that characterize this type of fighting broaden the range of opportunities and obligations counterinsurgents face. While many have looked to jus in bello constraints on the just conduct of war to guide this effort, jus post bellum requirements for the just cessation of conflict provide a better framework in which to discuss how soldiers and marines may effectively and ethically pursue insurgents while simultaneously building host-nation capacity to govern politically, economically, and militarily. This paper demonstrates how jus post bellum obligations provide an important structure within which counterinsurgents may understand the full range of their obligations to the host nation and its population, best pursue insurgents while honoring their commitment to noncombatant immunity, and set the standard for what constitutes the end of the conflict and the appropriate point for military disengagement.
