This is a study of friendship in international politics. It offers the history of friendship, and shows the role of friendship in building various legal and political orders on both equal and unequal terms. Told through an examination of sources ranging from diplomatic letters and bilateral treaties to poems and philosophical treatises.

This is the first book-length study of the role that friendship plays in diplomacy and international politics. Through an examination of a vast amount of sources ranging from diplomatic letters and bilateral treaties, to poems and philosophical treatises, it analyses how friendship has been talked about and practised in pre-modern political orders and modern systems of international relations. The study highlights how instrumental friendship was for describing and legitimising a range of political and legal engagements with foreign countries and nations. It emphasises contractual and political aspects in diplomatic friendship based on the idea of utility. It is these functions of the concept that help the world stick together when collective institutions are either embryonic or no more.

When strangers meet in social clubs, watch reality television, or interact on Facebook, they contribute to the social glue of mass society—not because they promote civic engagement or democracy, but because they enact the sacred promise of friendship. Where most theories of nationalism focus on issues of collective identity formation, Kaplan’s novel framework turns attention to compatriots’ experience of solidarity and how it builds on interpersonal ties and performances of public intimacy. Combining critical analyses of contemporary theories of nationalism, civil society, and politics of friendship with in-depth empirical case studies of social club sociability, Kaplan ultimately shows that strangers-turned-friends acquire symbolic, male-centered meaning and generate feelings of national solidarity.

International friendship is a distinct type of interstate relationship, and that as such, it can contribute to capture aspects of international politics that have long remained unattended. This book offers a framework for analyzing friendship in international politics by presenting a variety of conceptual approaches and empirical cases.

How nations move from war to peace Is the world destined to suffer endless cycles of conflict and war? Can rival nations become partners and establish a lasting and stable peace? How Enemies Become Friends provides a bold and innovative account of how nations escape geopolitical competition and replace hostility with friendship. Through compelling analysis and rich historical examples that span the globe and range from the thirteenth century through the present, foreign policy expert Charles Kupchan explores how adversaries can transform enmity into amity—and he exposes prevalent myths about the causes of peace. Kupchan contends that diplomatic engagement with rivals, far from being appeasement, is critical to rapprochement between adversaries. Diplomacy, not economic interdependence, is the currency of peace; concessions and strategic accommodation promote the mutual trust needed to build an international society. The nature of regimes matters much less than commonly thought: countries, including the United States, should deal with other states based on their foreign policy behavior rather than on whether they are democracies. Kupchan demonstrates that similar social orders and similar ethnicities, races, or religions help nations achieve stable peace. He considers many historical successes and failures, including the onset of friendship between the United States and Great Britain in the early twentieth century, the Concert of Europe, which preserved peace after 1815 but collapsed following revolutions in 1848, and the remarkably close partnership of the Soviet Union and China in the 1950s, which descended into open rivalry by the 1960s. In a world where conflict among nations seems inescapable, How Enemies Become Friends offers critical insights for building lasting peace.

Intermarriage and the Friendship of Peoples examines the racialization of identities and its impact on mixed couples and families in Soviet Central Asia. In marked contrast to its Cold War rivals, the Soviet Union celebrated mixed marriages among its diverse ethnic groups as a sign of the unbreakable friendship of peoples and the imminent emergence of a single "Soviet people." Yet the official Soviet view of ethnic nationality became increasingly primordial and even racialized in the USSR's final decades. In this context, Adrienne Edgar argues, mixed families and individuals found it impossible to transcend ethnicity, fully embrace their complex identities, and become simply "Soviet." Looking back on their lives in the Soviet Union, ethnically mixed people often reported that the "official" nationality in their identity documents did not match their subjective feelings of identity, that they were unable to speak "their own" native language, and that their ambiguous physical appearance prevented them from claiming the nationality with which they most identified. In all these ways, mixed couples and families were acutely and painfully affected by the growth of ethnic primordialism and by the tensions between the national and supranational projects in the Soviet Union. Intermarriage and the Friendship of Peoples is based on more than eighty in-depth oral history interviews with members of mixed families in Kazakhstan and Tajikistan, along with published and unpublished Soviet documents, scholarly and popular articles from the Soviet press, memoirs and films, and interviews with Soviet-era sociologists and ethnographers.
