The Limits of Military Power: The United States in Iraq

Military strategy and tactics evolved rapidly during the twentieth century to account for the new reality of a modern world that has grown increasingly smaller and connected. While new weapons and new methods of waging war forever changed the nature of combat, the advent of sub-national actors capable of waging campaigns against the most powerful nation-states heralded an era of military operations other than war. At various points in history, the United States military has pioneered a number of innovative weapons systems and tactics to counter traditional threats. However, the nation’s defense establishment has at times been slow to adapt to changes and evolutions in warfare giving rise to the oft-cited admonishment that “the military is always preparing for the last war.” The end of the Cold War initiated a period of uncertainty and new missions for the US military which culminated in the War on Terror launched in the aftermath of the terrorist attacks of September 11. This was done without a firm understanding of the more holistic nature of international relations and the need to account for non-state national threats. More specifically, US military prowess was applied unevenly in the new campaigns in Afghanistan and Iraq. This chapter explores the evolution of modern warfare and the application of new strategy and tactics within the Iraq conflict. Specifically, the essay examines the rise of asymmetric warfare within the broader scope of the emergence of fourth generation warfare and the impact of the Iraq War on American military planning and force structures.
