Dan Reiter, "Untied Hands: How States Avoid the Wrong Wars" (Cambridge UP, 2025)

How do states advance their national security interests? Conventional wisdom holds that states must court the risk of catastrophic war by “tying their hands” to credibly protect their interests. Dan Reiter overturns this perspective with the compelling argument that states craft flexible foreign policies to avoid unwanted wars. Through a comprehensive analysis of key international crises, including the Berlin, Taiwan Straits, and Cuban Missile Crises, and the Korean and Vietnam Wars, Reiter provides new perspectives on the causes of wars, the role of international alliances, foreign troop deployments, leader madness, and the impact of AI on international relations. With critical insights into contemporary foreign policy challenges, such as America’s role in NATO, the risks of war with China, containing a resurgent Russia, and the dangers of nuclear war, Untied Hands: How States Avoid the Wrong Wars (Cambridge University Press, 2025) is essential reading for anyone interested in understanding how states can effectively manage international crises while avoiding the wrong wars.

hat is the relationship between culture and trade? In Trading on Art: Cultural Diplomacy and Free Trade in North America Sarah E. K. Smith, an Associate Professor in the Faculty of Information and Media Studies at Western University and the Canada Research Chair (Tier 2) in Art, Culture and Global Relations, examines the history of cultural relations between Canada, the USA and Mexico at the turn of the twenty-first century. The book considers how North America was conceptualised by cultural practices such as art and video, as well as how the arts engaged and responded to free trade agreements in that period. As the world confronts a very different trading and cultural context, the book is essential reading for anyone interested in the future, as well as the past, of cross-national cultural exchange. The book will also be available open access in 2026 Learn more about your ad choices. Visit megaphone.fm/adchoices

In his new book, The Deepest Border: The Strait of Gibraltar and the Making of the Hispano-African Border(Stanford, 2019), Sasha D. Pack considers the Strait of Gibraltar as an untamed in-between space—from “shatter zone” to borderland. Far from the centers of authority of contending empires, the North African and Southern Iberian coast was a place where imperial, colonial, private, and piratical agents competed for local advantage. Sometimes they outmaneuvered each other; sometimes they cooperated. Gibraltar entered European politics in the Middle Ages, and became a symbol of the Atlantic Empire in the Early Modern period (the Pillars of Hercules of Emperor Charles V are featured on the Spanish flag to this day), but Pack’s study focuses on the nineteenth century. Europe’s new imperialism, Britannic naval supremacy, the age of steam, the ever-present danger of cholera, all mark the change of a Spanish-Moorish border into a multilateral one. So too does the multicultural mix of Europeans and North Africans, Muslims, Jews, Catholics, and Protestants who brought a spirit of convivencia (mutual toleration) into the region, unlike the nineteenth- and twentieth- century homogenizing nationalism that was at play elsewhere. In the middle of this theater, Dr. Pack follows the careers of adventuresome entrepreneurs, who manipulated the weak enforcement of conflicting laws in overlapping jurisdictions for their own gain. He calls these characters “slipstream potentates” because they maneuvered creatively in the wakes of great ships of state on their courses in the seas of international politics. (Other historians have called them “the last Barbary pirates.”) They bring color and detail to this already gripping narrative of international politics in Spain and North Africa in the century between Napoleon and Franco. Sasha D. Pack is Associate Professor of History at the University of Buffalo. He studies Modern Europe, Spain and Portugal, and the Mediterranean, focusing on transnational and political history. Krzysztof Odyniec is a historian of the Early Modern Spanish Empire specializing in culture, diplomacy, and travel. He completed his PhD in 2017 at UC Berkeley where he is now a Visiting Scholar and a Fellow in the Berkeley Connect in History program. Learn more about your ad choices. Visit megaphone.fm/adchoices

More than a century and a half after Robert E. Lee surrendered to Ulysses S. Grant, historians are still searching for exactly when the U.S. Civil War ended. Was it ten weeks afterward, in Galveston, where a federal commander proclaimed Juneteenth the end of slavery? Or perhaps in August of 1866, when President Andrew Johnson simply declared “the insurrection is at an end”?  That the answer was elusive was baffling even to a historian of the stature of Michael Vorenberg, whose previous work served as a key source of Steven Spielberg’s Lincoln. Vorenberg was inspired to write this groundbreaking book, finding its title, Lincoln's Peace, in the peace Lincoln hoped for but could not make before his assassination. A peace that required not one but many endings, as Vorenberg reveals in these pages, the most important of which came well more than a year after Lincoln’s untimely death. To say how a war ends is to suggest how it should be remembered, and Vorenberg’s search is not just for the Civil War’s endpoint but for its true nature and legacy, so essential to the American identity. It’s also a quest, in our age of “forever wars,” to understand whether the United States’s interminable conflicts of the current era have a precedent in the Civil War—and whether, in a sense, wars ever end at all, or merely wax and wane.

Charles de Gaulle is one of the greatest figures of twentieth century history. If Sir Winston Churchill was (in the words of Harold Macmillan) the "greatest Englishman In history", then Charles de Gaulle was without a doubt, the greatest Frenchman since Napoleon Bonaparte. Why so? In the early summer of 1940, when France was overrun by German troops, one junior general who had fought in the trenches in Verdun refused to accept defeat. He fled to London, where he took to the radio to address his compatriots back home. “Whatever happens,” he said, “the flame of French resistance must not be extinguished and will not be extinguished.” At that moment, Charles de Gaulle entered history. For the rest of the war, de Gaulle insisted he and his Free French movement were the true embodiment of France. Through sheer force of his personality and the grandeur of his vision of France, he inspired French men and women to risk their lives to resist the Nazi occupation. Usually proud and aloof, but almost always confident in his own leadership, he quarreled violently with Churchill, Roosevelt and many of his own countrymen. Yet they knew they would need his help to rebuild a shattered France. Thanks to de Gaulle, France was recognized as one of the victorious Allies when Germany was finally defeated. Then, as President of the Fifth Republic, he brought France back from the brink of a civil war over the war in Algeria. And, made the difficult decision to end the self-same war. Thereafter he challenged American hegemony, took France out of NATO, and twice vetoed British entry into the European Community in his pursuit of what he called “a certain idea of France.” Julian Jackson, Professor of History at Queen Mary College, University of London, past winner of the Wolfson History Prize and the winner in 2018 of the Paris Book Award for his book on De Gaulle--De Gaulle (Harvard University Press, 2018)--has written a magnificent biography, the first major reconsideration in over twenty years. Drawing on the extensive resources of the recently opened de Gaulle archives, Jackson reveals the conservative roots of de Gaulle’s intellectual formation and upbringing, sheds new light on his relationship with Churchill, and shows how de Gaulle confronted riots at home and violent independence movements abroad from the Middle East to Vietnam. No previous biography has so vividly depicted this towering figure whose legacy remains evident in present-day France. In short Professor Jackson has written a superb book, which in every way possible is a glittering ornament in the biographical art.

Sanctions have become the go-to foreign policy tool for the United States. Coercive economic measures such as trade tariffs, financial penalties, and export controls affect large numbers of companies and states across the globe. Some of these penalties target nonstate actors, such as Colombian drug cartels and Islamist terror groups; others apply to entire countries, including North Korea, Iran, and Russia. U.S. policy makers see sanctions as a low-cost tactic, but in reality these measures often fail to achieve their intended goals--and their potent side effects can even harm American interests.  Backfire: How Sanctions Reshape the World Against U.S. Interests (Columbia UP, 2022) explores the surprising ways sanctions affect multinational companies, governments, and ultimately millions of people around the world. Drawing on interviews with experts, policy makers, and people in sanctioned countries, Agathe Demarais examines the unintended consequences of the use of sanctions as a diplomatic weapon. The proliferation of sanctions spurs efforts to evade them, as states and firms seek ways to circumvent U.S. penalties. This is only part of the story. Sanctions also reshape relations between countries, pushing governments that are at odds with the U.S. closer to each other--or, increasingly, to Russia and China.  Full of counterintuitive insights spanning a wide range of topics, from commodities markets in Russia to Iran's COVID response and China's cryptocurrency ambitions, Backfire reveals how sanctions are transforming geopolitics and the global economy--as well as diminishing U.S. influence. This insider's account is an eye-opening, accessible, and timely book that sheds light on the future of sanctions in an increasingly multipolar world.

A sitting Democratic president who chooses not to run for re-election, a vice president running out of the president’s shadow, and a Republican nominee trying to make a political comeback amidst accusations of collusion – welcome to the 2024 1968 presidential election. What we think we know about the election has been challenged, however, by a new book by Luke A. Nichter, a professor of history and presidential studies at Chapman University. In The Year That Broke Politics: Collusion and Chaos in the Presidential Election of 1968 (Yale UP, 2024) Nichter reexamines the campaign and shows how the ‘68 election foreshadowed our current political landscape. The 1968 presidential race was a contentious battle between vice president Hubert Humphrey, Republican Richard Nixon, and former Alabama governor George Wallace. The United States was reeling from the assassinations of Martin Luther King, Jr., and Robert F. Kennedy and was bitterly divided on the Vietnam War and domestic issues, including civil rights and rising crime. Drawing on previously unexamined archives and numerous interviews, Luke A. Nichter upends the conventional understanding of the campaign. Nichter chronicles how the evangelist Billy Graham met with Johnson after the president’s attempt to reenter the race was stymied by his own party, and offered him a deal: Nixon, if elected, would continue Johnson’s Vietnam War policy and also not oppose his Great Society, if Johnson would soften his support for Humphrey. Johnson agreed. Nichter also shows that Johnson was far more active in the campaign than has previously been described; that Humphrey’s resurgence in October had nothing to do with his changing his position on the war; that Nixon’s “Southern Strategy” has been misunderstood, since he hardly even campaigned there; and that Wallace’s appeal went far beyond the South and anticipated today’s Republican populism. This eye-opening account of the political calculations and maneuvering that decided this fiercely fought election reshapes our understanding of a key moment in twentieth-century American history.

Emerging from an award-winning article in International Security, China's Gambit examines when, why, and how China attempts to coerce states over perceived threats to its national security. Since 1990, China has used coercion for territorial disputes and issues related to Taiwan and Tibet, yet China is curiously selective in the timing, target, and tools of coercion. This book offers a new and generalizable cost-balancing theory to explain states' coercion decisions. It demonstrates that China does not coerce frequently and uses military coercion less when it becomes stronger, resorting primarily to non-militarized tools. Leveraging rich empirical evidence, including primary Chinese documents and interviews with Chinese and foreign officials, this book explains how contemporary rising powers translate their power into influence and offers a new framework for explaining states' coercion decisions in an era of economic interdependence, particularly how contemporary global economic interdependence affects rising powers' foreign security policies.

World War II endures in the popular imagination as a heroic struggle between good and evil, with villainous Hitler driving its events. But Hitler was not in power when the conflict erupted in Asia—and he was certainly dead before it ended. His armies did not fight in multiple theaters, his empire did not span the Eurasian continent, and he did not inherit any of the spoils of war. That central role belonged to Joseph Stalin. The Second World War was not Hitler’s war; it was Stalin’s war. Drawing on ambitious new research in Soviet, European, and US archives, Stalin's War: A New History of World War II (Basic Books, 2021) by award winning historian, Sean McMeekin, Professor of History at Bard College, revolutionizes our understanding of this global conflict by moving its epicenter to the east. Hitler’s genocidal ambition may have helped unleash Armageddon, but as McMeekin shows, the war which emerged in Europe in September 1939 was the one Stalin wanted, not Hitler. So, too, did the Pacific war of 1941–1945 fulfill Stalin’s goal of unleashing a devastating war of attrition between Japan and the “Anglo-Saxon” capitalist powers he viewed as his ultimate adversary. McMeekin also reveals the extent to which Soviet Communism was rescued by the US and Britain’s self-defeating strategic moves, beginning with Lend-Lease aid, as American and British supply boards agreed almost blindly to every Soviet demand. Stalin’s war machine, McMeekin shows, was substantially reliant on American materiél from warplanes, tanks, trucks, jeeps, motorcycles, fuel, ammunition, and explosives, to industrial inputs and technology transfer, to the foodstuffs which fed the Red Army. This unreciprocated American generosity gave Stalin’s armies the mobile striking power to conquer most of Eurasia, from Berlin to Beijing, for Communism. A groundbreaking reassessment of the Second World War, Stalin’s War is revisionist history at its very best: breaking down old paradigms and narratives and bringing to the fore new understandings of the historical process. All from a historian who has the best claim to be the closest, modern-day American equivalent of A. J. P. Taylor. Charles Coutinho Ph.

In a 2012 opinion piece bemoaning the state of the US Senate, Washington Post columnist Dana Milbank cited a “leading theory: There are no giants in the chamber today.” Among the respected members who once walked the Senate floor, admired for their expertise and with a stature that went beyond party, Milbank counted Sam Nunn (D-GA). Nunn served in the Senate for four terms beginning in 1972, at a moment when domestic politics and foreign policy were undergoing far-reaching changes. As a member and then chairman of the Senate Armed Services Committee, he had a vital impact on most of the crucial national security and defense issues of the Cold War era and the “new world order” that followed—issues that included the revitalization of the North Atlantic Treaty Organization's military capability, US-Soviet relations, national defense reorganization and reform, the Persian Gulf conflict, and nuclear arms control. In this first full account of Nunn’s senatorial career, Frank Leith Jones reveals how, as a congressional leader and “shadow secretary of defense,” Nunn helped win the Cold War, constructing the foundation for the defense and foreign policies of the 1970s and 1980s that secured the United States and its allies from the Soviet threat. At a time of bitter political polarization and partisanship, Nunn’s reputation remains that of a statesman with a record of bipartisanship and a dedication to US national interests above all. His career, as recounted in Sam Nunn: Statesman of the Nuclear Age (University Press of Kansas, 2020), provides both a valuable lesson in the relationships among the US government, foreign powers, and societies and a welcome reminder of the capacity of Congress, even a lone senator, to promote and enact policies that can make the country, and the world, a better and safer place.

Marshall Chair of Military Studies in the Department of National Security and Strategy at the US Army War College in Carlisle, Pennsylvania.
