C. Anthony Pfaff, ©2024 C. Anthony Pfaff; Monograph from the US Army War College, Strategic Studies Institute. US Army War College Press; As wars in Ukraine and Gaza continue with little end in sight, the sense of urgency to determine how they should end is increasing, given how the wars could end. A just war aims to establish a better state of peace, but a better state of peace may not always be achievable, and even when it is achievable, it may not be good enough. When that is the case, actors must determine on what terms to settle, given what they think they can achieve based on relative capabilities and cost tolerances. The resulting “maximin” solution, a practical approach where actors maximize the minimum they can achieve, provides a range of solutions. But taking only these factors into account is not likely to produce an enduring or more perfect peace. To get to a “good enough” state of peace, justice concerns—in this case framed by the just-war tradition—play a role. By impacting what counts as costs and benefits and placing boundaries on what actors should accept independently of those costs and benefits, the just-war tradition can help actors construct more durable settlements. The experiences in Ukraine and Gaza further illustrate gaps in the just-war tradition, which this book also addresses.

John R. Deni and Lisa A. Aronsson, ©2024 John R. Deni; Monograph from the US Army War College Press, Strategic Studies Institute, US Army War College; What more can US allies in Europe do to assist Ukraine militarily? More broadly, what can the United States expect from its closest allies in Europe in strategic competition with Russia and China? In this monograph, John R. Deni and Lisa A. Aronsson assess whether US allies and partners in Europe can continue providing military assistance to Ukraine or expand assistance, while preserving their own national security and fulfilling their NATO commitments. They also explore what the Russia-Ukraine War reveals about the role of European allies in future iterations of strategic competition. Their findings indicate European allies remain firmly in support of assisting Ukraine politically, even if the reasons for allied support vary across Europe. Despite agreeing support is necessary, European allies face several hurdles on the path toward scaling up military assistance to Ukraine. The reasons for the hurdles vary, and some exceptions exist, but Deni and Aronsson find without continued, sustained US engagement, leadership, and presence in Europe, Washington may find itself with few European allies by its side. To facilitate and sustain continued success in transatlantic burden sharing, the authors provide several practical recommendations for US policymakers to consider.

Satellites in the Russia-Ukraine War Ron Gurantz Monograph by the US Army War College, Strategic Studies Institute, US Army War College Press Satellites and counterspace systems have shown themselves to be important parts of modern warfare in the Russia-Ukraine War but have also been subject to various restrictions to prevent escalation. This monograph examines the role of satellites and counterspace systems in the Russia-Ukraine War’s high-technology warfare and the effects of satellite proliferation and commercialization on the conduct of the war. It also analyzes the restrictions under which space-based capabilities have been operating and the implications of these limits for future conflicts—a subject that has received little attention. Relying on an exhaustive study of open-source material and the application of limited-war theory to the case of the Russia-Ukraine War, this monograph will help officials and strategists better understand the roles satellites are likely to play in future conflicts and the limits under which states will operate them as governments seek to gain military advantage and avoid escalation.

Lieutenant General Robert C. Richardson Jr.: Central Pacific Theater Army Commander for Admiral Chester W. Nimitz 1943–45; James D. Scudieri; Historical Study Monograph by the US Army War College, US Army War College Press, Strategic Studies Institute; This monograph analyzes Lieutenant General Robert C. Richardson Jr.’s service as de facto theater Army commander to Admiral Chester W. Nimitz from August 1943 to June 1945. It focuses on the theater-strategic level when Richardson led US Army Forces in Central Pacific Area and US Army Forces, Pacific Ocean Areas. This study highlights the context of Richardson’s operating environment beginning with prewar plans, the realities of early wartime defeats, and the state of joint operating procedures. It assesses Richardson’s accomplishments in exercising Landpower in the Pacific, across the entire range of today’s Army war-fighting and Joint functions and discusses the implications of posturing for large-scale combat operations in competition, crisis, and conflict. These assessments are relevant to US Army Pacific today in its four current roles of Theater Joint Force Land Component Command, Combined Joint Task Force, Combined Joint Force Land Component Command, and Army Service Component Command.

A Call to Action: Lessons from Ukraine for the Future Force John A. Nagl, Project Director Katie Crombe, Chief of Staff Integrated Research Project by the US Army War College, US Army War College Press, Strategic Studies Institute This book explores the changing character of war through the lens of the Russia-Ukraine War. The authors analyze the conflict’s history, each side’s warfighting functions, the role of multidomain operations, and more. The radical changes in the character of war suggest the United States is at a strategic inflection point. The authors draw lessons from both the Ukrainians and the Russians to suggest improvements for the United States. Advances in drone technology, cyber warfare, and electromagnetic warfare pose new technological vulnerabilities and possibilities. In addition, the war has highlighted the roles of allies in deterrence and training as well as how leadership styles within the military—specifically, in the implementation of mission command—can be a decisive factor. As the Russia-Ukraine War has demonstrated, modern conflict touches a plethora of domains; thus, having sufficient personnel who are ready to fill a variety of capacities will be critical in the future. Finally, the war has shown history and justice are critical aspects of going to war and achieving peace, so crafting a narrative and satisfying stakeholders will be necessary for establishing a stable world order. The Russia-Ukraine War foreshadows the challenges the United States will face in future conflict and highlights the keys to adapting to modern warfare.

The US Army War College’s 2023 Conference on the People’s Liberation Army (PLA) was held February 22 to 24, 2023, at Carlisle Barracks, Pennsylvania. The conference, entitled “Decisive Decade: PRC Global Strategy and the PLA as Pacing Challenge,” featured presentations on PRC global and regional strategy, and the PLA’s enabling role by experts from a wide range of academic, media, and government agencies and organizations. The conference papers better defined the notion of the PLA as a pacing challenge as evidenced by PRC strategies and activities in various regions to build a much stronger appreciation of how PLA operations in these locations matter to each other and the whole of the PRC’s broader national strategy. The event also included presentations on Chinese military deterrence and potential justifications for a cross-Strait conflict following US House Speaker Pelosi’s visit to Taiwan in August 2022. Specific topics included the PRC’s acceleration of military reforms and its extending reach; how the PRC can use various regional crises to justify military action against Taiwan; countering PRC military strength in Northeast Asia; and the PRC’s growing economic and security engagements with Latin America, Africa, South Asia, Russia, and Europe.

In a world where technology is rapidly advancing and available to the masses, companies and policymakers face a daunting reality—non-state actors are using innovation for sinister purposes. While artificial intelligence (AI) and autonomous systems promise enhanced threat detection, terrorist groups are exploiting these tools for recruitment and attacks. The future is concerning as AI becomes more widespread and autonomous systems and augmented reality redefine society. A groundbreaking report is born from a collaboration between NATO COE-DAT and the US Army War College Strategic Studies Institute. This book unveils a grim forecast that terrorists are poised to exploit advances in artificial intelligence, autonomous systems, augmented reality, biotechnology, and nanotechnology. The line between reality and fiction blurs in the age of rapid technological evolution, urging governments, industries, and academia to unite in crafting ethical frameworks and regulations. As geopolitical tides shift, NATO stresses national responsibility in combating terrorism and advocating for collective strength against the looming specter of technology-driven threats. However, questions linger. Can regulatory frameworks keep pace with technological innovation? Will industry prioritize ethical considerations over profit margins?
