PREFACE
THE TITLE of this book, A World Safe for Commerce, has within it both light and dark undertones, swirling in tension like the two halves of the “yin-yang” symbol in Chinese Daoism. On the one hand, by playing off of Woodrow Wilson’s inspiring statement to Congress on April 2, 1917, that the United States had to enter the European war to “make the world safe for democracy,” I wish to evoke the idea that commerce has been and can still be a force for peace, and thus a worthy end of any state’s foreign policy. Yet by shifting the phrase to its commercial equivalent, I want to stress the dark and calculating side of power politics that the vast majority of American leaders since the eighteenth century have so effectively practiced. And this includes that great liberal internationalist, Woodrow Wilson himself. For more than two and half centuries, American policy makers have typically conceived of “world” as meaning not the planet, but theirworld, the places on the earth that most determine their interests and concerns. And when they conceive of keeping that world “safe,” they are almost always thinking of how to ensure continued access to the goods and markets that will keep the economy strong and national security intact. If other powers help to promote and secure the expansion of this commercial world, great. Peace can prevail. But if others challenge America’s access to this world, watch out! Conflict and war may have to be chosen, even when other powers want a peaceful status quo. This book represents a sustained exploration of this and other such fundamental tensions, and the trade-offs in policy that go with them.
The book represents the third in an unplanned trilogy of books that seeks to offer a more dynamic view of international politics. When I was a second-year grad student, a professor of mine made an offhand comment that Kenneth Waltz’s famous Theory of International Politics had already shown us how great powers respond to outside forces (the “systemic” level in Waltz’s language), and that all interesting work in international relations would now come from the study of domestic politics and leaders (the “unit” level). Since I had already taken to heart critiques of Waltz’s book which underscored, above all, that it provided a far too static picture of the international system, I remember approaching him after class and stating that I thought there was still a lot more to be done at the systemic level. Most important, we needed to show how trends in systemic-level factors such as relative power and trade dependence force great powers to alter, often radically, their foreign policy behaviors. I recall he looked rather bemused, said something like “Good luck!” and walked off.
At the time, it was commonly believed that systemic or “neorealist” theories of power politics could only explain broad recurring patterns in great power relations, and that for any purchase on the specific behavior of states, one had to “dip down to the unit level” (to use a popular phrase from those days). I resisted this view then and have resisted it ever since. Great powers don’t simply face general and largely fixed systemic factors such as bipolarity (two large states) and multipolarity (many large states), as Waltz claimed. They also must deal with their specific relative positions within those polarities and how those positions are expected to change over time. They must answer questions such as: Who is bigger than whom, and by how much? Are we rising or declining in our level of power and economic dependence compared to other states in the pecking order? How have past decisions shaped current trends not just in military power, but also in economic and technological power? And perhaps most important of all, what do we expect will happen in the future, independent of
current trends, that might affect our ability to access the materials and markets we need to sustain our economic power base and thus our long-term national security?
The first book, TheOriginsofMajorWar, focused mostly on how dynamic trends in a state’s relative military power position caused it to act either moderately in foreign policy when it was inferior but rising in relative power and wished to buy time for future growth—or aggressively, given beliefs that it was declining from a strong current position and would be vulnerable to attack or coercion later. The second book, Economic Interdependence and War, took one step back in the causal chain. It showed how changes in a great power’s dependence on trade and financial flows, combined with expectations of the future commercial environment, could lead those in power to believe that the state was either rising or declining in long-term power. If expectations of future trade were positive, leaders could expect the state to grow in power, and would thus have more reason for moderate foreign policies. But if expectations turned sour and leaders came to see that others were either cutting the state off from trade and investment, or were likely to do in the future, then they could anticipate decline and be more inclined to hard-line policies to rectify the situation. In short, both books, drawing from the preventive war literature, demonstrated that anticipated decline is a major reason for great powers to turn to policies that lead to risky crises or war, with the second book also showing one very important reason for why leaders come to believe their states are indeed in significant decline.
This book builds on the theoretical arguments of the first two books, but also adds three new elements to help complete the larger dynamic argument I am developing. First, drawing from offensive realism but going beyond it, I argue that in any situation of anarchy where there is no central authority to protect states from the threatening actions of others, great powers have an incentive not only to seize opportunities to expand their territorial-military positions as a hedge against potential attacks down the road. They
also have an incentive to grab opportunities to expand their economic power spheres—the realms of trade and commerce they rely upon for continued growth—to reduce the chances that others will cut them off from future access to vital goods and markets. The fact that the United States and China today share this age-old drive to expand and protect their commercial realms goes a long way to explaining why in 2013 Beijing created the Belt and Road Initiative (BRI) to continue its “going out” policies from the 1990s and 2000s, and why Washington is so keen to ensure that the BRI does not hurt U.S. trade ties in Asia, Africa, and Latin America. Indeed, the reason underlying China’s expansion outward parallels one of the foundational drives propelling American expansion after 1790— namely, the need for a larger sphere that could ensure continued access to raw materials, investments, and markets.
Yet the United States in its past, as with China over the last forty years, could not seize opportunities to increase its economic sphere without also considering the risk that this might upset other major powers. Smart great powers understand that overly hard-line behavior can cause a spiral of mistrust and hostility that may lead other states to reduce trade or even to engage in military actions to protect their own economic spheres. This is the second way that I extend past work. I seek to build a dynamic realist theory that integrates offensive realist insights on the need to expand as a hedge against the future with defensive realist insights on the need to worry that one might acquire a reputation for being a state with an aggressive, even pathological, character. Rational leaders will take into account both needs simultaneously as they make difficult decisions about the level of moderation or assertiveness in their foreign policies. And they will assess these needs in light of the severity of external changes in power and commerce, shifting to more hard-line policies either when they have reason to fear deep decline, or when they are rising but believe that without stronger policies, they will start to peak and decline in the near future (for the latter, think of the United States after 1895 and China after 2007).
The third new element is the book’s analysis of exactly how rational leaders interested in security go about making assessments of the other’s character assessments that, in conjunction with power trends, shape the way such leaders estimate the level of future threat arising from the external environment. Since these leaders are focused on the external environment—the other state’s character, and whether it is, like their state, rational and securityseeking, or something else altogether—this is not a “dipping down to the unit level” to explain why these leaders make the decisions they do. Rather, it is simply an unpacking of the various forces that shape the behavior of potential adversaries and that must go into any rational security-maximizing leader’s evaluation of the other’s future willingness to trade and to trade at high levels. This leader’s commercial expectations for the future, in short, come from somewhere, and in chapter 2 I unpack “the where,” using the assumption that nothingfromwithinthisleader’sstateis shaping his or her expectations. The expectations are shaped only by factors outside of the state. This assumption preserves the core assertion of all systemic realist arguments: namely, that rational leaders focused on national security are driven only by changes in the external situation the state faces, not by domestic pressures bubbling up “from below.” So while I later add complexity to my initial barebones argument, the book also bounds its argument in a way that gives the theory a strong measure of parsimony, and most importantly, allows it to be tested against the many theories that do start from unit-level domestic pressures to explain a state’s behavior.
The empirical focus of the book is on the main cases of American foreign policy over the last two and a half centuries. These cases, from the War for Independence to the Cold War, reveal something important. They show that American policy makers, far from simply responding to pressures from below or personal impulses, have regularly operated from a logic that I claim is a universal and overhanging “force from above” for all great powers, or at least for those in the post-1660 age of modern globalized commerce.
American leaders, in sum, are not naïve, nor are they all that different from the leaders of the European and Asian states explored in my first two books. In fact, they understand the commerce of power politics better than perhaps any other single group of state leaders over the last three centuries. Even if they cloak their policies in the warm and fuzzy language of liberal individualism and freedom, and occasionally find themselves shaped (and trapped) by this language, they prove themselves to be, first and foremost, careful calculators of national security through the lens of economic and commercial power. And for the most part, the world is a better place for it.
ACKNOWLEDGMENTS
THIS BOOK has a long history, and there are many people to thank for their help along the way. I first presented some of my initial and largely inchoate ideas on economic interdependence and international conflict back in my last year of graduate school at the University of Chicago, and I had a chance to return a quarter century later to present what I hoped was a much improved and better supported version of those ideas at the University of Chicago’s Program on International Politics, Economics, and Security (PIPES). John Mearsheimer and Charles Lipson were there on both occasions to offer direct and insightful comments on my overall logic and evidence. The dynamic realist theory that I present in this book may ultimately show that offensive realism should be best thought of as what physicists call a “special case” within a larger theoretical framework. But it was John’s version of offensive realism that convinced me that all great powers are forced by their uncertainty about the future to seek to expand their realms of power—in the military-territorial sense for John; and in the commercial-economic sense for me. And it was Charles’s graduate seminar on international political economy, which opened with Waltz’s seminal book, that pushed me to consider how the issues of the IPE and security subfields might be brought together within a single framework.
The rigor of the critiques offered that day at the PIPES seminar decisively shifted the direction of this book, and for that I want to also thank Paul Poast and Marc Trachtenberg and the graduate student participants who were there that day. Around the same time, I also greatly benefited from a seminar at MIT, where many of the case studies in the book were discussed. In particular, I wish to
thank Frank Gavin, Ken Oye, Roger Peterson, Barry Posen, Dick Samuels, and Stephen Van Evera for their great comments on that day. Also significant to the development of the argument were two presentations over two years I did at workshops on trade and conflict at the University of California, Irvine, organized by Michelle Garfinkel and Stergios Skaperdes of Irvine’s economics department. Feedback from Michelle and Stergios, as well as from Tommaso Sonno, helped me see more clearly how economists might go about formalizing my expectations-based argument. I’ve held off publishing the formal model that I developed out of those sessions for my next book. But the exercise itself served to hone the deductive logic behind my argument. I also want to thank Mike Beckley and Pat MacDonald for comments on my theoretical argument and the First World War chapter at the online 2020 APSA convention, Michael Mastanduno for his astute critique of the final draft, and Chris Carter, Gary Goertz, Stephan Haggard, and David Waldner for valuable discussions on the book’s methodological approach.
As the book was nearing completion, I had a chance to present chapters from the manuscript in three quite distinct venues. The theory chapters were presented to the Institute for Security and Conflict Studies seminar on international security at George Washington University. For suggestions that helped me refine many aspects of the final argument, I thank Alex Downes, Charlie Glaser, and Joanna Spear, as well as the attending GWU grad students. At Haifa University’s workshop on the future of the world order, sponsored by Israel Science Foundation, I received great feedback on my chapter on the future of U.S.-China relations from an amazing group of scholars, including Lars-Erik Cederman, Tom Christensen, Andrew Hurrell, John Ikenberry, Arie Kacowicz, Deborah Larson, Jack Snyder, and the workshop’s organizer, Benny Miller. The same chapter was also presented at a conference on the future of the U.S. dollar and the global economic order at Credit Suisse Bank in Zurich. I was surprised and delighted to have John Major, former prime minister of Britain, as my discussant. Sir John offered trenchant
comments about the practical implications of my trade expectations logic that significantly shaped the way I think about China’s ability to use the global system for its advantage.
At the University of Virginia I benefited greatly from a scrub session on the book and two later discussions organized through the Miller Center and the program on Democratic Statecraft. Will Hitchcock, David Leblang, Jeff Legro, Melvyn Leffler, Allen Lynch, John Owen, Len Schoppa, Todd Sechser, and Mark Schwartz provided incisive comments on specific chapters. I was also fortunate to receive feedback from a number of smart graduate students who directly shaped the book’s ultimate form: Josh Cheatham, Ghita Chraibi, Justin Gorkowski, James Kwoun, Yuji Maeda, Sowon Park, Sunggun Park, Angela Ro, John Robinson, Melle Scholten, Luke Schumacher, and Chen Wang. Six terrific undergrad students also offered great comments on the overall argument: Sam Brewbaker, Jenny Glaser, Lily Lin, Adrian Mamaril, Dao Tran, and Nick Wells. I’m also very grateful to four of my former grad students who took time away from their own busy academic careers to read the near-finished manuscript and help me hone the final product: Kyle Haynes, David Kearn, Mike Poznansky, and Brandon Yoder. And, of course, I need to thank four anonymous reviewers for their insightful comments and my wonderful editors at Princeton University Press: Bridget Flannery-McCoy, who guided the book through the challenges of the review process and the crafting of the final product; and Eric Crahan, who first inspired me to write a book on American foreign policy building on the ideas from my previous book for Princeton.
Finally, I dedicate this book to my family: V. Natasha Copeland and my two amazing children Liam and Katya. They kept my spirit up through the long and winding road that was this book project: tolerating long hours in my room going through documents when I could have been playing more soccer, volleyball, or Clue with them; and helping me relax with Seinfeld, Harry Potter movies, and Beatles
albums when I seemed just a bit too stressed out. Couldn’t have done it without you!

Introduction
THE WORLD has changed. Over the past decade, we have witnessed a distinct shift toward a renewed competition between the great powers. The green light that China seems to have given to Russia’s brutal invasion of Ukraine in February 2022 and its subsequent saber-rattling over Taiwan six months later only served to reinforce concerns that have been building within the American foreign policy community since at least 2010. Just how intense this great power competition will become is uncertain. But what seems clear is that the optimism of the 1990s—when pundits and politicians alike saw growing economic interdependence and a rules-based international order as fostering long-term prosperity and peace between the United States, China, and Russia—is gone. In its place is talk of new cold wars and even military conflict. A rising China now seems willing to flex its muscles not just in its region but around the globe. Leaders in Beijing have not only challenged the U.S. navy for dominance in the South China Sea and the Pacific but also have signaled that they intend to extend China’s economic and political influence not just to Eurasia and Africa, but to an area Americans have always considered their backyard: Latin America. Russia, with a GDP the size of Italy, may have been reduced to the status of a middle power within the larger Sino-American competition. Yet its leaders’ very resentment of this fact, combined with Russia’s vast energy resources and the willingness to take military actions against neighbors—Georgia in 2008, Ukraine in 2014 and again in 2022— make Russia a continued threat to the global economic and political system. Even if Russian leaders cannot contribute to this system, they can undermine it, thereby interfering with the plans of both the
United States and China as they struggle for more influence and control around the world.
Russia’s continued ability to play the role of spoiler, however, should not distract us from a larger geopolitical fact: it is the bipolar struggle between the United States and China that is the new Great Game of the twenty-first century. Because both sides have nuclear weapons, we can expect leaders in Washington and Beijing to be inherently reluctant to engage in behavior that might raise the risk of actual war. And we can be thankful that at least one key lesson came out of the Cold War: that neither side can afford to push the system to anything that looks remotely like the Cuban Missile Crisis of 1962. This is the good news.
Yet as this book shows, there is also bad, or at least concerning, news. Great powers need continued economic prosperity to support their militaries and to ensure that they can maintain stability at home in the face of other states’ possible efforts to subvert it. They thus have an ongoing drive to expand their economic and commercial power spheres beyond their borders, and to support these spheres with strong navies and offensive power-projection capability. The American ongoing military presence in the Middle East and the Indo-Pacific regions since World War II and China’s growing naval support for its Belt and Road Initiative are only two obvious examples from recent history. This means that even in the nuclear age, great powers will struggle to improve their geoeconomic positions around the world. They will worry that their adversaries might decide to cut them off from access to vital raw materials, investments, and markets (“RIM”). In short, commercial strugglesfor prosperity and position remain an essential element of great power grand strategy, and these struggles can end up leading to crises that increase the probability of devastating war between the powers.
To see the inherent dangers, we need only remember that the Second World War in the Pacific came directly out of the tightening of an economic noose around Japan beginning in the early 1930s
and ending with a total allied embargo on oil exports to Japan in 1941. Chinese leaders are very much aware that the scenario of 1941, even more than that of 1914, is the one to avoid. Yet like Japanese leaders after 1880, they also know that China must work hard to extend its commercial presence, even at the risk of a spiral of hostility, if it is to sustain the growth that has made it the stable and secure superpower that it is today. This tension between needing to expand one’s economic sphere of influence and wanting to avoid an escalatory spiral that might restrict access to vital goods and markets is baked into the DNA of modern great power politics. It is a tension, as we will see, that the United States has faced repeatedly since the founding of the American republic. When it comes to explaining how competitions over commerce affect the likely behavior of great powers, there are two big questions that need to be examined in depth. What exactly is the role that commerce plays in driving states either toward more accommodating soft-line actions or toward more assertive hard-line postures, including the initiation of military containment and war against adversaries? And how significant is this role compared to the many other causes of cooperation and conflict that scholars have identified? This book seeks to answer these questions through a study of American foreign policy from the eighteenth century to contemporary U.S.-China relations. Yet this is not simply a book that explores the fascinating changes in American behavior toward the outside world since 1750 and then applies historical lessons to twenty-first century geopolitics. More than that, it represents a test of the relative explanatory power of the key theories of international relations (IR) for one very important country over time and across highly varied circumstances. These theories can be divided into two main groups: “realist” theories that focus on howthreatsexternalto a state will force almost any type of leader or elite group toward similar policies; and “liberal” theories that emphasize how forces internal to a state shape and constrain its behavior independent of the effects of the external factors. It is clear to nearly all IR scholars
that the United States, due to its strong liberal democratic foundations, poses a hard case for any realist theory, including the one offered here. We just expect American leaders to “think differently” about global affairs, and to be guided more by a sense of moral values, domestic pressures, and ideological ends than by traditional European notions of Realpolitik. So as that great philosopher (and sometime singer) Frank Sinatra might have said, if realist theory can make it here, it should be able to make it anywhere.
This book has three specific goals. The first is the building of a better, more dynamic realist theory of international relations, one that can resolve some of the problems with the two main versions of systemic realism in the field—namely, offensive realism and defensive realism. Systemic realists start with the common assumption that in anarchy, with no central authority to protect them, great powers will be primarily driven by factors that transcend domestic issues: factors such as differentials in relative power and uncertainty about the economic and military threats that other states pose, now and into the future. Yet offensive and defensive realists remain divided over the role of such systemic forces. By bringing together the insights of both forms of realism, the book establishes a stronger foundation for thinking about how states grapple with trade-offs presented by their external situations. Great powers do worry about building power positions that can handle problems that may arise in the future, as offensive realists stress. But they are also concerned that being overly assertive in the pursuit of this position can lead them into undesired spirals of hostility and conflict, as defensive realists emphasize.
By fusing these insights and then extending them into the realm of commercial geopolitics, this book goes beyond the limitations of current realist theory. It reveals the importance of two crucial variables to the decision-making process of any great power: the intensity of a state’s drive to extend and protect its economic power sphere to ensure a base-line level of access to key raw materials,
investments, and markets; and leader expectations about how willing adversaries are to allow the state future access to areas of trade and finance beyond its immediate power sphere. Modern realist theories tend to focus primarily on the military and territorial aspects of the great power security competition, downplaying the economic. These former aspects are important, to be sure. But by tying drives for commercial spheres of influence to expectations of trade beyond those spheres, I show that the overall trade environment and the way leaders anticipate changes in that environment regularly play an even more fundamental role in driving the foreign policies of great powers.
The second main goal of the book is to show that this new more dynamic and commercial approach to systemic realism can more than hold its own with the very case that has always proved problematic for realism: the United States and its foreign policies over the last two and a half centuries. Contemporary realists often buy into the liberal premise that America is exceptional, that it is founded in an ideology that rejected “Old World” aristocratic power politics in favor of the liberal pursuit of individual happiness, and that this outlook often leads the United States to act in ways that are contrary to realist predictions. Such realists are inclined to accept traditional arguments that the perceived need to spread democracy or protect liberal institutions abroad have been driving forces for why American leaders moved to a more globalist strategy after 1916 and why Washington continues to promote “liberal hegemony” long after the end of the Cold War. This starting assumption can lead offensive and defensive realists to give too much away to domestic-level explanations for American foreign policy behavior. To be sure, U.S. leaders and officials have at times sought to extend American liberalism’s reach when they could do so at low cost or when having liberal states in one’s sphere was seen as essential to countering the extension of an opponent’s sphere, as during the Cold War. And at certain points in U.S. history, as I show, bottom-up domestic pressures within a pluralist American state did indeed play important
roles in shaping policy. This book’s empirical chapters demonstrate, however, that the importance of commercial and power-political factors on American foreign policy behavior over the last two and a half centuries has been significantly underplayed, at least by political scientists if not always by neo-Marxist revisionist historians. From the formation of the republic to the current era, U.S. leaders, concerned about long-term national security, have been driven by a combination of commercial factors and relative power trends that have often overshadowed the ideological and domestic determinants of foreign policy. Americans, it turns out, are extremely smart and savvy realists, precisely because they have intuitively understood from the get-go the importance of dynamically fusing offensive and defensive realist insights with commercial power politics.
In the testing of its dynamic realist approach, this book does something unusual. Almost every book of historically based political science tries to set its theory against “competing arguments” in order to show that the causal factors posited by other theories are less useful in explaining the empirical cases of conflict and war than the pet theory of the book in question. This leads to endless cycles of debate as to which scholar’s factors were most critical to the understanding of controversial cases. My method is different. By recognizing that almost every case involves numerous key causal factors, I seek to identify the causal role that these factors are playing in a particular case, such as Woodrow Wilson’s decision to enter World War I or Franklin Roosevelt’s and Harry Truman’s policies that helped establish the post–World War II global order. Specifically, I ask questions such as: To what extent was a factor propellingthe leader to act, rather than acting as a facilitatingfactor for that action, or perhaps as a constraining factor that forced the postponement of the action? Was the factor merely acceleratingthe leader’s timetable for action or perhaps only reinforcing the original decision by giving added reasons to act, rather than being the factor that propelled the leader to act in the first place? As I discuss in chapter 2, by analyzing the various roles different causal factors play
