A bold, revisionist study which challenges modern misconceptions about the creation of power and the operations of war, from a Professor of Strategic Studies War and power are two of the most-widely discussed issues in all of human history, and yet they are, time and again, misunderstood - often disastrously so. Whilst we might think the outcome of war is determined by so-called 'Great Powers' who dominate their opponents with their impressive size and military prowess, the reality of modern conflict, as renowned strategic historian Professor Phillips Payson O'Brien demonstrates, is very different. He urges us instead to look for 'Full Spectrum Powers'. For if we are considering how powerful a nation is and who will win a war, we need to think less about weapons, and more about the economies and societies that produce them; less about individual battles, and more about sustaining campaigns and alliances in which states operate. Using fascinating examples from the late 19th century to the present day, War and Power explains how misunderstanding war and power has led to terrible, even preventable conflicts - such as the war in Ukraine - and how more accurate analysis can help us consider the potential conflict between the US and China. War and Power provides a bold new way of understanding the dangerous world around us.

Phillips O'Brien is one of the keenest observers of modern strategy, and his new book takes a deep historical look at the evolution of warfare and its implications for conflicts like the ongoing one in Ukraine. -- Francis Fukuyama, author of The End of History and the Last Man
As wars rage across the world, Phillips O’Brien offers powerful insights into the past, present, and future of war and power. This book is vital reading for anyone grappling with America’s uncertain place in today’s global order. -- Alexander Vindman * New York Times–bestselling author of The Folly of Realism *
