In the widest sense, a particular country’s foreign policy pertains to the myriad ways in which that country’s people engage and interact with peo- ple and institutions from other countries. The book focuses mainly on a particular class of people who have a particular responsibility for conducting a given country’s foreign policy—chiefly its elected officials, military personnel, and diplomats. These people estab- lish and enforce the rules governing how the rest of their country’s people may or may not engage or interact with foreigners. Some of these laws are fairly innocuous and impose only minor or temporary inconveniences. For example, U.S. law prohibits me from purchasing or owning certain items covered by U.S. sanc- tions. If I’m caught breaking the law, I could be prosecuted. Collectively, the drafting and enforcing of such regulations necessitates a large and relatively intrusive state—larger, say, than a state that allowed me to purchase any good or service, from any place, regardless of the circumstances of its production or provision. But war, that most visible of all instruments of foreign policy, imposes major and oftentimes lasting effects on individuals’ lives and liberty. War today is often seen as a foreign policy failure, but it wasn’t always that way. The famed Prussian military theorist Carl von ix PEACE, WAR, and LIBERTY Clausewitz described war as the continuation of policy by other means. Even militarily strong countries, however, would gener- ally prefer to attain peacefully what could be secured by force. The reasons are fairly obvious and straightforward: War is unpredict- able. War is costly. War is violent. Policymakers, therefore, should not embark on such a course lightly or with unrealistic expecta- tions about quick success. Clausewitz spoke of friction, the fog of war, and how battle plans rarely survive first contact with the enemy. Winston Churchill, a celebrated wartime leader, was sim- ilarly mindful of war’s uncertainty. “The Statesman who yields to war fever,” he wrote in his memoir, My Early Life, “is no longer the master of policy, but the slave of unforeseeable and uncontrol- lable events.”1 The liberals of Clausewitz’s day, whom today we might call lib- ertarians, had still more reasons for wanting to solve international problems by peaceful means. They knew that war often contrib- uted to the rise of state power and therefore constituted a threat to liberty. This book approaches warfare as they did: as an occasionally necessary evil, not an endeavor that should be used as a vehi- cle for promoting social change. The book is organized around a theory—or, more accurately, a set of different theories—about what best creates security and prosperity. Simply, what causes peace? And relatedly, what can we do to advance individual liberty through peaceful means? In what instances, if any, is war the appropriate recourse? And what foreign policies other than war are more effective? This book addresses these questions. x PREFACE Because I am an American, writing chiefly for an American audience, I will focus mostly on U.S. foreign policy. I believe that America’s founding generation, in particular, proposed a foreign policy broadly consistent with libertarian principles, favoring peaceful engagement through trade and cultural exchange and holding a skepticism of warfare as an instrument of policy. Despite this U.S.-centric approach, I believe that the book has insights for many people in many countries. Identifying the particular pathol- ogies that have afflicted U.S. foreign policy over time—fool- ish wars fought well, noble wars fought badly, well-intentioned restrictions on travel or trade that had unfortunate side effects, alliances created or dissolved—surely has relevance for other countries at other times. The claim that U.S. foreign policy is like that of any other coun- try comes with a crucial proviso: U.S. foreign policy is bigger—a function of our great wealth and power. The scope of any one nation’s foreign policies is shaped by that nation’s physical con- text, including its geography, and by the disposition (i.e., friend or foe) of its neighbors. Scope is also constrained by a given country’s economic capacity to engage in all aspects of foreign policy—from conducting diplomacy to waging war. Relatively small, relatively weak, or relatively poor countries must necessarily prioritize what they do. Medium- and large-sized countries also set priorities but can have more of them. Even relatively affluent countries often choose to privilege one aspect of foreign policy (e.g., trade) over another (e.g., war). Iceland’s defense budget is effectively zero, as is Costa Rica’s. The United States began as a small, weak country. Its constitution forbade a xi PEACE, WAR, and LIBERTY standing army, and it struggled in its early days to deploy forces even into neighboring Canada or Mexico. Today, the United States possesses the world’s most powerful military. That vast force is capable of deploying in many places simultaneously and even performs many of the jobs that other countries assign solely to their diplomats.
