Continued Evolution of U. S. Law of Armed Conflict Implementation

"U.S. policies implementing the Law of Armed Conflict (LOAC) have increasingly restricted military activities over the past two decades. Greater concern for civilian casualties in particular has motivated the U.S. military to take increasing precautions in its planning and deterred it from undertaking military actions anticipated to place civilians at risk. Despite the clear impact of such implementations on military operations in recent years, however, relatively little attention has been paid to assessing their potential future direction. This report aims to fill this gap by surveying potential strategic, technological, and normative trends that may affect the future evolution of U.S. LOAC implementation, and assessing the resulting implications for the U.S. military. The report's assessment of these trends suggests that the U.S. military is likely to find it increasingly difficult to reconcile its operational responsibilities with political pressures to adopt highly restrictive implementations of the LOAC in the years to come, highlighting the need for policy options to mitigate both operational and political risks. The types of adversaries and operational environments that the United States is likely to face will tend to increase the difficulty of distinguishing between combatants and civilians and limiting collateral damage. At the same time, normative trends are likely to further increase the pressure on the United States to adopt restrictive rules of engagement and other implementations of the LOAC that emphasize the importance of avoiding civilian casualties, or place domestic public and foreign partner support for military operations at risk."--Back cover.
