As anyone who is interested in military history can attest, an early step is finding a suitable ‘survey’ book—a foundational text that provides both overview and analysis, leading to other works for further reading. This can be a difficult balance to strike, between the barebones entries in the encyclopedia and thousand-page paperweights that cover every troop movement and intercepted communiqué. Both have value; however, for most readers of history, both are likely less than desirable. In Military History for the Modern Strategist, Brookings Institution senior fellow Michael O’Hanlon packages crisp recaps of America’s major conflicts from 1861 to 2022 with analysis of grand strategy, offering an excellent starting point for aspiring strategists looking to apply lessons from past conflicts to today’s and tomorrow’s challenges….Military History for the Modern Strategist arrives at a critical transition point in U.S. military history. White papers abound from civilian think tanks and military red cells about what ‘could’ happen, but the lessons of history are equally important in strategy planning. O’Hanlon says it best as he concludes: ‘Military history is fundamentally sobering. For that reason its value is hard to exaggerate.’ This book is a necessary historical guide that will help inform the hard decisions that the next generation of planners and strategists will have to make, when the United States once again goes to war.

Michael O’Hanlon has devoted his career to thinking and writing about the causes, courses, and consequences of war so that future such tragedies are less likely to occur, and less devastating when they do. With Military History for the Modern Strategist O’Hanlon has produced a focused, consumable volume full of lessons from America’s past wars – lessons that are more apt and urgent today than at any time since the Cold War’s end. The book is an insistent reminder that it is only the knowledge, perceptions, and choices of America’s leaders, expressed in strategy, that bind the destructive activities of war to the nation’s political purpose, and to its principles. Reading this book will help the country’s leaders design those strategies with humanity and humility.

In Military History for the Modern Strategist, Michael O’Hanlon demonstrates once again why he is one of the outstanding defense analysts of our time. He has astutely recognized that at a time of profound strategic uncertainty and change, the smartest thing we can do is to go back to basics: start with the military history of our nation over the past century and a half and build upon its lessons to fashion a new grand strategy that can carry us through the coming era. It is a brilliant approach, and he has executed it marvelously well in these pages. Here he provides all of the key information and insights from America’s major conflicts since the Civil War in a way that is both elegant and concise—precisely right as the basis for new strategic thinking.

Michael O’Hanlon has created a unique American military history primer for policymakers that particularly emphasizes two great truths: wars never proceed along the path belligerents expect, and quick, cheap victories are extremely rare.

History humbles us—hence the reason we continue to ignore Clio’s lessons. Dr. O’Hanlon’s superb book, however, returns Clio to her indispensable role for the strategist and policymaker, whilst also reminding us that to prepare for future (and inevitable) conflict, we need to learn from our past. Dr. O’Hanlon’s book serves as a welcome primer to guide undergraduate and graduate classrooms alike in understanding that without history’s instruction we will fail.

O’Hanlon focuses on the operational level of war, though he deftly interweaves discussion of tactics and technology, strategy and policy, and civil-military relations and politics as appropriate. His descriptions and analyses of these conflicts are clear and balanced. Though readers already familiar with these conflicts might gain little in terms of new factual knowledge, even experts will benefit from the analytical framing of key decisions by civilian and military leaders. O’Hanlon’s consistent focus throughout the book on contingency—at what point things might have gone differently—is a particular strength. In short, this book successfully delivers what the sub-title promises: a concise discussion of America’s major wars since 1861 through the eyes of an experienced analyst…. The modern strategist will indeed benefit from his overview of America’s major wars since 1861 and the warnings to remain humble and ready for the unexpected.
