Understanding future armed conflict requires recognizing both the constants and changes in the nature of war. The U.S. Army Operating Concept emphasizes the importance of clear thinking about war for military professionals at all levels. Neglecting the continuities in the nature of war can lead to challenges in decision-making, planning, and training. It is crucial to grasp that war is inherently political, with military actions needing to align with broader political objectives. The experiences in Afghanistan and Iraq have validated the significance of understanding these key continuities in the nature of war.
