War Made New

Technology, Warfare, and the Course of History, 1500 to Today

Book
Foreign policy analyses written by CFR fellows and published by the trade presses, academic presses, or the Council on Foreign Relations Press.

A sweeping, epic history that ranges from the defeat of the Spanish Armada to the war on terrorism, War Made New is a provocative new vision of the rise of the modern world through the lens of warfare. Acclaimed author Max Boot explores how innovations in weaponry and tactics have not only transformed how wars are fought and won but also have guided the course of human events, from the formation of the first modern states, to the collapse of the Soviet Union, to the coming of al-Qaeda.

Boot argues that the past five centuries of history have been marked not by gradual change in how we fight but instead by four revolutions in military technology—and that the nations who have successfully mastered these revolutions have gained the power to redraw the map of the world. Boot brings these moments of transformation to vivid life through gripping combat scenes.

Magisterial.
The New York Times

For the Gunpowder Age, he argues that firearm technology brought from China shattered the ritualized combat of the Middle Ages as innovators such as Swedish King Gustavus Adolphus and the Duke of Wellington incorporated artillery and cavalry in new ways, leading to the rise of the Western powers. Exploring the Industrial Revolution, Boot discusses how breakthrough inventions such as the steam engine led to a rapid mechanization of fighting technology in the mid-nineteenth century and terrifying new levels of bloodshed, from the Prussian victory over the Austrian Empire at the Battle of Koniggratz to the newly industrialized Japanese navy's devastation of the Russian fleet at Tsushima. For the Second Industrial Revolution, Boot focuses on how the oil-driven combustion engine and the advent of combat aviation culminated in the battlefield breakthroughs of World War Two, from the German blitzkrieg of France to the American firebombing of Tokyo, which would lead to the rise of global superpowers.

Brilliantly crafted.
The Wall Street Journal

War Made New concludes with the ongoing Information Revolution, beginning with the Gulf War in 1991. Boot describes how the use of precision-guided missiles along with stealth planes and cruise missiles granted the United States critical advantage over enemies in Iraq and Afghanistan, and also looks at how the world's last superpower can combat the asymmetric tactics of groups such as al-Qaeda.

Maj. Gen. Robert H. Scales, The Wall Street Journal

Superb. ... Mr. Boot's historical sections, commencing with the Spanish armada and marching briskly through four centuries of organized mayhem, can be enjoyed even by the reader who is aware of the broad parameters of the conflicts he describes. But what is utterly fascinating is Mr. Boot's section on what is happening now in modernizing the battle field.

Joe Goulden, The Washington Times

[Boot] is, all hyperbole aside, a modern-day Thucydides, telling the story of war and why it matters. In this rich and highly readable tome, he focuses on four revolutions in technology and doctrine. ... Boot is not only an excellent historian, but also an excellent writer.Furthermore, he explains the implications not just for armed conflict, but also for military and political alliances, coronations, and redrawn boundaries around the globe. ... Based on his thorough understanding of military history.

Mark Yost, The Philadelphia Inquirer

Max Boot traces the impact of military revolutions on the course of politics and history over the past 500 years. In doing so, he shows that changes in military technology are limited not to war fighting alone, but play a decisive role in shaping our world. Sweeping and erudite, while entirely accessible to the lay reader, this work is key for anyone interested in where military revolutions have taken usand where they might lead in the future.

U.S. Senator John McCain

Meticulously researched … A timely and important work, providing an excellent thumbnail sketch of the sometimes simultaneous strokes of genius, luck, and technological smarts that kings and generals have used for centuries to best their enemies in the field.

Christian Science Monitor

War Made New is an ambitious effort that ultimately succeeds in capturing the general sweep of history. ... The product of prodigious research and concise analysis. ... Engaging.

Frank Hoffman, Armed Forces Journal

War Made New is a tour-de-force of warfare over the past half-millennium.... It is fast-paced and reads like a novel. Boot grabs the readers and causes him or her to turn the page to find out what happened next. This is not only essential reading for anyone who is a serious student of warfare, technology, and the like, but for anyone wanting to know what has made the world unfold the way it has over the past five centuries.

Capt. George Galdorisi, U.S. Navy (Retired), Naval Institute Proceedings

I really enjoyed reading it. Boot is a fantastic writer who eloquently describes the march of military history from the 15th century to the present day, using vignettes like the British drubbing the Spanish Armada in 1588 and Japan's smashing of the Russian fleet in 1905 to illustrate certain key points.

Philip Carter, Slate

While of substantial length (624 pages), it is so well written and so full of information and insight that was new to me that it didn't seem long enough. ... War Made New is one of those books that had me saying, 'Ah hah, now I understand,' over and over again.

John Steele Gordon, American Heritage

Max Boot provides both facts and a deeper examination of causes, producing an interesting, readable and compelling examination of military transformations throughout history.

If you take military history seriously, you'll simply devour this book.

Military Book Club

Mr. Boot is ably filling the role occupied for many years by John Keegan, the famed British author of classics like The Face of War and The Mask of Command. Both use a similar approach: Illustrate broad military trends with specific examples, and embed the analysis in an entertaining historical narrative accompanied by commentary. Fans of Mr. Keegan's will enjoy Mr. Boot.

Bruce Berkowitz, New York Sun

Max Boot has the intellectual audacity and meticulous scholarship to rearrange the kaleidoscope of military history. War Made New is a classic that must be savored.... A wonderful book, combining impressive scholarship and keen insights. It is not possible to read this book without stopping every twenty or so pages to say, 'I didn't know that,' and without frequently pausing to reflect on the future.

Bing West, Marine Corps Gazette

It's not only a terrific read; it's a cheap education on how, for half a millennium, machines made war and war made machines. The research is impressive, the judgments are soundand Max Boot's a strong, clear writer. ... This is a book for both the general reader and reading generals.

Ralph Peters, New York Post

Boot has bitten off a big chunk of history. But thanks to his knowledge of the facts and his skill in setting them down, he has served up a first-class book.

St. Louis Post Dispatch

A dazzling history of war.

The Arkansas Democrat-Gazette

Readable and informative, this book provides a valuable overview of how military innovations can abruptly affect the course of history. Highly recommended.

Library Journal

From bronze cannons to smart bombs, this engaging study examines the impact of new weaponry on war by spotlighting exemplary battles, including famous epics like the defeat of the Spanish Armada and the attack on Pearl Harbor along with obscure clashes like the 1898 Battle of Omdurman, in which a British colonial force mowed down Sudanese tribesmen with machine guns. Boot (The Savage Wars of Peace: Small Wars and The Rise of American Power) gives due weight to social context: advanced weapons don't spell victory unless accompanied by good training and leadership; innovative doctrine; an efficient, well-funded bureaucracy; and a 'battle culture of forbearance' that eschews warrior ferocity in favor of a soldierly ethos of disciplined stoicism under fire. These factors flourish, he contends, under a rationalist, progressive Western mindset. The author, a journalist, and senior fellow at the Council on Foreign Relations, enlivens his war stories with profiles of generals from Gustavus Adolphus to Norman Schwarzkopf and splashes of blood and guts. Boot distills 500 years of military history into a well-paced, insightful narrative.

Publishers Weekly

Max Boot's War Made New condenses the evolution of Western warfare from the Renaissance to the present into a single readable and entertaining volume.

Geoffrey Wawro, History Book Club

While much has been written in recent years about the so-called 'Revolution in Military Affairs,' Max Boot is the first scholar to place it within the broad sweep of history, and in the context of the rise of the West in world affairs since 1500. In so doing, he not only tells a remarkable tale, but he compels us all, even those obsessed solely with contemporary military affairs, to ask the right questions and to distinguish what is truly new and revolutionary from what is merely ephemeral. He has rendered a valuable service, and given us a fascinating read at the same time, so we are doubly in his debt.

Paul Kennedy, Professor of History at Yale University and author of The Rise and Fall of the Great Powers

War Made New is impressive in scope. What is equally impressive is its unique interpretation of the causal relationship between technology, warfare and the contemporary social milieu. This is a superb thinking-person's book, which scrutinizes conventional historical wisdom through a new lens.

Lt. Gen. Bernard E. Trainor, USMC (ret.), coauthor of Cobra II: The Inside Story of the Invasion and Occupation of Iraq

Max Boot's book takes hundreds of years of tactical battle history and reduces it to an incisive narrative of how war has changed. By providing such a coherent view of the past, he has pointed us toward the future. What is doubly impressive is how he draws surprising, fresh lessons from wars we thought we knew so much about but in fact didn't.

Robert D. Kaplan, author of Imperial Grunts

From Drake's ships harrying the Armada up the Channel to U.S. Special Forces deploying in the mountains of Afghanistan, Boot's narrative takes the widest possible view, yet it always crackles with fascinating detail and swift, adept character sketches. Drawing examples from scores of battlefields, War Made New shows how nations have seized technological opportunities, or failed to do so at the steepest imaginable cost. Boot makes events from the dawn of the gunpowder era as immediate to contemporary America as is the threat of terrorist attack, all the while telling a story as enthralling as it is significant.

Richard Snow, Editor, American Heritage

A powerful tome.

History Wire

Excellent. ... Cogent and compelling, War Made New should be required reading for anyone dealing with military issues.

Tom Miller, Military.com

Boot provides a sweeping, accessible narrative.

National Review

Boot's detail-packed discussion of the impact of military revolutions on the course of modern history makes War Made New one of the most provocative, thought-stimulating books in recent memory.

In the Middle East, Israel and Iran are engaged in what could be the most consequential conflict in the region since the wars in Afghanistan and Iraq. CFR’s experts continue to cover all aspects of the evolving conflict on CFR.org. While the situation evolves, including the potential for direct U.S. involvement, it is worth touching on another recent development in the region which could have far-reaching consequences: the diffusion of cutting-edge U.S. artificial intelligence (AI) technology to leading Gulf powers. The defining feature of President Donald Trump’s foreign policy is his willingness to question and, in many cases, reject the prevailing consensus on matters ranging from European security to trade. His approach to AI policy is no exception. Less than six months into his second term, Trump is set to fundamentally rewrite the United States’ international AI strategy in ways that could influence the balance of global power for decades to come. In February, at the Artificial Intelligence Action Summit in Paris, Vice President JD Vance delivered a rousing speech at the Grand Palais, and made it clear that the Trump administration planned to abandon the Biden administration’s safety-centric approach to AI governance in favor of a laissez-faire regulatory regime. “The AI future is not going to be won by hand-wringing about safety,” Vance said. “It will be won by building—from reliable power plants to the manufacturing facilities that can produce the chips of the future.” And as Trump’s AI czar David Sacks put it, “Washington wants to control things, the bureaucracy wants to control things. That’s not a winning formula for technology development. We’ve got to let the private sector cook.” The accelerationist thrust of Vance and Sacks’s remarks is manifesting on a global scale. Last month, during Trump’s tour of the Middle East, the United States announced a series of deals to permit the United Arab Emirates (UAE) and Saudi Arabia to import huge quantities (potentially over one million units) of advanced AI chips to be housed in massive new data centers that will serve U.S. and Gulf AI firms that are training and operating cutting-edge models. These imports were made possible by the Trump administration’s decision to scrap a Biden administration executive order that capped chip exports to geopolitical swing states in the Gulf and beyond, and which represents the most significant proliferation of AI capabilities outside the United States and China to date. The recipe for building and operating cutting-edge AI models has a few key raw ingredients: training data, algorithms (the governing logic of AI models like ChatGPT), advanced chips like Graphics Processing Units (GPUs) or Tensor Processing Units (TPUs)—and massive, power-hungry data centers filled with advanced chips.  Today, the United States maintains a monopoly of only one of these inputs: advanced semiconductors, and more specifically, the design of advanced semiconductors—a field in which U.S. tech giants like Nvidia and AMD, remain far ahead of their global competitors. To weaponize this chokepoint, the first Trump administration and the Biden administration placed a series of ever-stricter export controls on the sale of advanced U.S.-designed AI chips to countries of concern, including China.  The semiconductor export control regime culminated in the final days of the Biden administration with the rollout of the Framework for Artificial Intelligence Diffusion, more commonly known as the AI diffusion rule—a comprehensive global framework for limiting the proliferation of advanced semiconductors. The rule sorted the world into three camps. Tier 1 countries, including core U.S. allies such as Australia, Japan, and the United Kingdom, were exempt from restrictions, whereas tier 3 countries, such as Russia, China, and Iran, were subject to the extremely stringent controls. The core controversy of the diffusion rule stemmed from the tier 2 bucket, which included some 150 countries including India, Mexico, Israel, Switzerland, Saudi Arabia, and the United Arab Emirates. Many tier 2 states, particularly Gulf powers with deep economic and military ties to the United States, were furious.  The rule wasn’t just a matter of how many chips could be imported and by whom. It refashioned how the United States could steer the distribution of computing resources, including the regulation and real-time monitoring of their deployment abroad and the terms by which the technologies can be shared with third parties. Proponents of the restrictions pointed to the need to limit geopolitical swing states’ access to leading AI capabilities and to prevent Chinese, Russian, and other adversarial actors from accessing powerful AI chips by contracting cloud service providers in these swing states.  However, critics of the rule, including leading AI model developers and cloud service providers, claimed that the constraints would stifle U.S. innovation and incentivize tier 2 countries to adopt Chinese AI infrastructure. Moreover, critics argued that with domestic capital expenditures on AI development and infrastructure running into the hundreds of billions of dollars in 2025 alone, fresh capital and scale-up opportunities in the Gulf and beyond represented the most viable option for expanding the U.S. AI ecosystem. This hypothesis is about to be tested in real time. In May, the Trump administration killed the diffusion rule, days before it would have been set into motion, in part to facilitate the export of these cutting-edge chips abroad to the Gulf powers. This represents a fundamental pivot for AI policy, but potentially also in the logic of U.S. grand strategy vis-à-vis China. The most recent era of great power competition, the Cold War, was fundamentally bipolar and the United States leaned heavily on the principle of non-proliferation, particularly in the nuclear domain, to limit the possibility of new entrants. We are now playing by a new set of rules where the diffusion of U.S. technology—and an effort to box out Chinese technology—is of paramount importance. Perhaps maintaining and expanding the United States’ global market share in key AI chokepoint technologies will deny China the scale it needs to outcompete the United States—but it also introduces the risk of U.S. chips falling into the wrong hands via transhipment, smuggling, and other means, or being co-opted by authoritarian regimes for malign purposes.  Such risks are not illusory: there is already ample evidence of Chinese firms using shell entities to access leading-edge U.S. chips through cloud service providers in Southeast Asia. And Chinese firms, including Huawei, were important vendors for leading Gulf AI firms, including the UAE’s G-42, until the U.S. government forced the firm to divest its Chinese hardware as a condition for receiving a strategic investment from Microsoft in 2024. In the United States, the ability to build new data centers is severely constrained by complex permitting processes and limited capacity to bring new power to the grid. What the Gulf countries lack in terms of semiconductor prowess and AI talent, they make up for with abundant capital, energy, and accommodating regulations. The Gulf countries are well-positioned for massive AI infrastructure buildouts. The question is simply, using whose technology—American or Chinese—and on what terms? In Saudi Arabia and the UAE, it will be American technology for now. The question remains whether the diffusion of the most powerful dual-use technologies of our day will bind foreign users to the United States and what impact it will have on the global balance of power.  We welcome your feedback on this column.
