Encyclopedia of U.S. Military Interventions in Latin America [2 volumes]: [2 volumes]


This unique reference shows how the United States has intervened militarily, politically, and economically in Central America, South America, and the Caribbean from the early 19th century to the present day.What do baseball, American war crimes, and a slice of watermelon have in common in the annals of Latin American history? Believe it or not, this disparate grouping reflects the cultural and historical remnants of America's military and political involvement in the region. As early as 1811, the United States began intervening in the affairs of Central America, South America, and the Caribbean … and it hasn't stopped since. This compelling reference analyzes both the major interventions and minor conflicts stemming from our nation's military operations in these areas and examines the people, places, legislation, and strategies that contributed to these events.In addition to documented facts and figures, the alphabetically organized entries in Encyclopedia of U.S. Military Interventions in Latin America present fascinating anecdotes on the subject, including why the United States once invaded Panama over a slice of watermelon, how an intervention in Nicaragua landed our country on trial for war crimes, and how the popularity of baseball in Latin America is a direct result of American influence. Primary source documents and visual aids accompany the content.

Escaping the Conflict Trap: Toward Ending Civil War in the Middle East (Middle East Institute Policy Series)


How can the current civil wars in the Middle East be resolved? This volume brings together academics, experts, and practitioners to explore this question. The book covers the history of civil wars in the region during the 20th century, and then examines the specific causes, drivers, and dynamics of the ongoing civil wars in Syria, Yemen, Libya, Afghanistan, and Iraq.Updated for a second edition, the book argues that while these are very different cases of civil war, there are patterns that are important to point out at the outset. First, while each of the conflicts appears to be a relatively recent phenomenon, each has a long historical tail. Second, each of the civil wars had deep and complex domestic drivers and dynamics over issues of governance, political identity, and resources; at the same time, all of the conflicts have had deep regional and international components. Finally, all of these civil wars have been affected by the presence or entrance of armed transnational non-state actors, which have had far greater involvement in the Middle Eastern civil wars compared to other regions. The book concludes that these conflicts will require a mixture of local, regional, and international interventions to bring them to an end, but that none of the conflicts are likely to end cleanly through either a negotiated settlement or a clear victory by one party or the other.Despite this pessimistic overall assessment, the book emphasizes that policymakers should use knowledge of civil wars in the Middle East to develop and pursue specific national, regional and global policies. These should be built around mitigating the worst effects of the conflicts and towards ultimate resolution.

Ethnic and Racial Minorities in the U.S. Military [2 volumes]: An Encyclopedia [2 volumes]


This encyclopedia details the participation of individual ethnic and racial minority groups throughout U.S. military history.Ethnic and Racial Minorities in the U.S. Military: An Encyclopedia is unique in its coverage of nearly all major ethnic and racial minority groups, as opposed to reference works that have focused only on individual ethnic or racial minority groups. It acknowledges the military contributions of African Americans, Asian Americans, French Americans, German Americans, Hispanic Americans, Irish Americans, Jewish Americans, and Native Americans. This timely work highlights the individuals and events that have shaped the experience of minorities in U.S. conflicts. The work provides a comprehensive encyclopedia covering the role of all major ethnic and racial minorities in the United States during wartime. Additionally, it considers how the integration of servicemen in the U.S. military set the precedent for the eventual desegregation of America's civilian population.

EU Security Strategies: Extending the EU System of Security Governance (Routledge Studies in European Security and Strategy)


This volume offers a coherent analysis of the European Union’s security strategies within a comparative framework. If the EU is to survive and prosper as an effective security actor, it requires that greater attention be devoted to taking a cohesive and common position on the relationship between EU foreign policy means and goals. The major claim of this edited collection is that there is a European grand security strategy that disciplines member state security strategies. That grand strategy has two distinct substantive goals: (1) the preservation and expansion of the EU system of security governance; and (2) the implementation of specific strategies to meet internal and external threats and sources of insecurity. The EU has sought to develop a grand security strategy that not only accounts for the proliferation of threats possessing a military or non-military character and differentiates between core and peripheral regions of interest, but also addresses the requirements to bridge the increasingly blurred boundary between internal and external security threats and the necessary reconciliation of the competing security preferences of its member states. The empirical contributions to this volume examine the EU security strategies for specific issue areas and regional threat complexes. These case studies assess whether and how those strategies have consolidated or expanded the EU system of security governance, as well as their successes and limitations in meeting the security threats confronting the EU and its member-states. This volume will be of great interest to students of EU policy, foreign policy, security studies and IR.

Europe's Cold War Relations: The EC Towards a Global Role (New Approaches to International History)


This thought-provoking collection analyses the European Community's external relations between 1957 and 1992, with a particular focus upon their broader impact and global significance. Reconceptualizing the long arc of the EC's international role, from its inception in the 1950s to the end of the Cold War, the chapters identify and assess the factors that either supported or impeded Europe's international projection within this period.Organized into three parts, the authors investigate the EC's relations with key countries and world regions, discuss its activities within key policy areas, and offer reflections and conclusions on the various arguments that are put forward. Each chapter considers the entire period from 1957-1992 to identify and explain overarching trends, key decisions and historical conjunctions through scholarly literature, key debates and original discussion of each topic or policy issue. A final chapter situates the main findings within wider contexts, situating the EC in Cold War history. Bringing together international history and international relations, this project allows for cross-disciplinary dialogue and the careful discussion of key concepts, analytical approaches, and empirical findings. Filling a gap in our understanding of the early development of the EC's role as an autonomous global actor, this book holds important messages for the modern day, as the EU's position in global politics continues to shape the world.

Explaining War and Peace: Case Studies and Necessary Condition Counterfactuals (Contemporary Security Studies)


This edited volume focuses on the use of ‘necessary condition counterfactuals’ in explaining two key events in twentieth century history, the origins of the First World War and the end of the Cold War. Containing essays by leading figures in the field, this book analyzes the causal logics of necessary and sufficient conditions, demonstrates the variety of different ways in which necessary condition counterfactuals are used to explain the causes of individual events, and identifies errors commonly made in applying this form of causal logic to individual events. It includes discussions of causal chains, contingency, critical junctures, and ‘powder keg’ explanations, and the role of necessary conditions in each. Explaining War and Peace will be of great interest to students of qualitative analysis, the First World War, the Cold War, international history and international relations theory in general.

Feminist Encounters in Statebuilding: The Role of Women in Making the State in Kosovo (Routledge Studies in Intervention and Statebuilding)


This volume provides one of the first comprehensive feminist readings of international statebuilding, with a specific focus on the case of Kosovo.Rather than simply showing how the state in Kosovo is being built by and through women and feminist encounters, this volume is interested to problematise women and feminist subjectivities vis-à-vis the state and statebuilding. The book challenges three main arguments related to the processes and subjects of statebuilding in Kosovo. First, the academic literature on Kosovo has a tendency to take the international intervention of 1999 as the originary point of statebuilding processes in Kosovo. Second, and relatedly, given Kosovo's unprecedented exposure to Western intervention and statebuilding, the majority of works start from the presumption that liberal interventionism in Kosovo (and elsewhere) is normatively more progressive than the previous system, and that the liberal interventionism and statebuilding are naturally gender progressive and gender-equal. The third argument has to do with the existing legal architecture on gender and women’s rights in contemporary Kosovo. The aim of the volume is to, on the one hand, problematise the evidence against the backdrop of everyday manifestations and/or performances of statebuilding and on the other hand interrogate the co-constitutive gender aspect. In terms of methodology, the volume brings together contributions that rely on traditional and multi-sited ethnography, and narrative research rooted in projects and initiatives in Kosovo. This allows the contributors to unearth new and silenced actors, entry points, subjects and subjectivities in processes of and related to statebuilding in Kosovo; feminist frictions and challenges to statebuilding in Kosovo; as well as encounters of heteronormative statebuilding.This book will be of much interest to students of statebuilding, Balkan politics, feminisms, and international relations, in general.

Fight, Flight, Mimic: Identity Mimicry in Conflict


FIight, Flight, Mimic is the first systematic study of deceptive mimicry in the context of wars. Deceptive mimicry -- the manipulation of individual or group identity -- includes passing off as a different individual, as a member of a group to which one does not belong, or, for a group, to 'sign' its action as another group. Mimicry exploits the reputation of the model it mimics to avoid capture (flight), to strike undetected at the enemy (fight), or to hide behind or besmirch the reputation of the model group ('false flag' operations). These tactics have previously been described anecdotally, mixed in with other ruses de guerre, but the authors show that mimicry is a distinct form of deception with its own logic and particularly consequential effects on those involved. The book offers a theory and game-theoretic model of mimicry, an overview of its use through history, and a deep empirical exploration of its modern manifestations through several case studies by leading social scientists. The chapters cover mimicry in the context of the Northern Ireland conflict, terrorism campaigns in 1970s Italy, the height of the Iraq insurgency, the Rwandan genocide, the Naxalite rebellion in India, and jihadi discussion forums on the Internet.

The First World War (Context and Commentary)


The Great War was the first in British history to involve virtually the entire population of Britain. A vast quantity of poems, fiction, essays, speeches, letters, memoirs and other written material was produced during 1914 and 1918 and Hibberd chooses both famous passages and excerpts which have never before been reprinted, from both the imaginative poetry and prose of the period, and documents such as newspapers and politicians' speeches. The linking commentary illuminates the very close relationship between the literature and history of this time, which is further highlighted by the chronological table, plates section and further reading sections.

The Future Law of Armed Conflict (The Lieber Studies Series)


Warfare is changing - and rapidly. New technologies, new geopolitical alignments, new interests and vulnerabilities, and other developments are changing how, why, and by whom conflict will be waged. Just as militaries must plan ahead for an environment in which threats, alliances, capabilities, and even the domains in which they fight will differ from today, they must plan for international legal constraints that may differ, too. This volume considers how law and institutions for creating, interpreting, and enforcing it might look two decades ahead - as well as what opportunities may exist to influence it in that time. Such assessment is important as the U.S. and other governments plan for future warfare. It is also important as they formulate strategies for influencing the development of law to better serve security, humanitarian, and other interests. This volume examines not just specific questions, such as how might a particular technology require adaptive interpretation of existing law, but also grand ones, such as whether law is capable at all of keeping up with these changes.

Germany and Nuclear Weapons in the 21st Century: Atomic Zeitenwende? (Routledge Global Security Studies)


This book is the first scholarly book to take a comprehensive look at Germany’s nuclear weapons policies in the 21st century.German foreign and security policy is facing a profound reorientation. Great power competition between the United States and both a revanchist Russia and a rising China, the return of war and nuclear threats to Europe, and the emergence of new technologies all force Germany to adapt. German policymakers and scholars increasingly speak of a pivotal Zeitenwende, an epochal turning point in history. How does Germany adapt its nuclear policies to these changing conditions?The volume brings together internationally renowned nuclear scholars and policy analysts from Germany and abroad. Focussing on German nuclear deterrence, arms control and disarmament as well as nonproliferation policies, the contributors assess how German leaders have navigated continuity and change, domestically and abroad. The volume concludes that Germany remains bound by dependence on the United States and its own conservatism. Within these parameters, German leaders have adapted slowly to change and continue to balance seemingly contradictory deterrence and disarmament goals.This book will be of much interest to students of nuclear proliferation, security studies, German politics and International Relations, as well as policymakers.

Germany at War [4 volumes]: 400 Years of Military History [4 volumes]


Written by experts for use by nonexperts, this monumental work probes Germany's "Genius for War" and the unmistakable pattern of tactical and operational innovation and excellence evident throughout the nation's military history.Despite having the best military forces in the world, some of the most advanced weapons available, and unparalleled tactical proficiency, Germany still lost both World Wars. This landmark, four-volume encyclopedia explores how and why that happened, at the same time examining Germany as a military power from the start of the Thirty Years' War in 1618 to the present day. Coverage includes the Federal Republic of Germany, its predecessor states, and the kingdoms and principalities that combined to form Imperial Germany in 1871.The Seven Years' War is discussed, as are the Napoleonic Wars, the Wars of German Unification (including the Franco-Prussian War), World War I, World War II, and the Cold War. In all, more than 1,000 entries illuminate battles, organizations, leaders, armies, weapons, and other aspects of war and military life. The most comprehensive overview of German military history ever to appear in English, this work will enable students and others interested in military history to better understand the sociopolitical history of Germany, the complex role conflict has played in the nation throughout its history, and why Germany continues to be an important player on the European continent.

Global Geostrategy: Mackinder and the Defence of the West


This is a new examination of Halford Mackinder’s seminal global geostrategic work, from the perspective of geography, diplomatic history, political science, international relations, imperial history, and the space age.Mackinder was a man ahead of his time. He foresaw many of the key strategic issues that came to dominate the twentieth century. Until the disintegration of the Soviet Union, western defence strategists feared that one power, or alliance, might come to dominate Eurasia. Admiral Mahan discussed this issue in The Problem of Asia (1900) but Mackinder made the most authoritative statement in "The Geographical Pivot of History" (1904). He argued that in the "closed Heart-Land of Euroasia" was a strategically placed region, with great resources, that if controlled by one force could be the basis of a World Empire. James Kurth, in Foreign Affairs, has commented that it has taken two World Wars and the Cold War to prevent Mackinder’s prophecy becoming reality. In World War I and World War II Germany achieved huge territorial gains at the expense of the Russian empire and the Soviet Union. In the former conflict the Russian empire was defeated by Germany but the western powers insisted that the territorial gains made by Germany, at the treaty of Brest-Litovsk, be given up. In World War II Britain and the US gave material support to Stalin’s totalitarian regime to prevent Nazi Germany gaining control of the territory and resources that might have been a basis for world domination. The west, highly conscious of Mackinder’s dictum (1919) that "Who rules East Europe commands the Heartland," quickly adopted policies to contain the Soviet Union. History has therefore proved Mackinder’s work to be of vital importance to generations of strategic thinking and he remains a key influence in the new millennium.This book will be of great interest to all students and scholars of strategic studies and military history and of geopolitics in particular.

A Global History of Relocation in Counterinsurgency Warfare


Relocation as a strategy and operational approach in war has reappeared in various forms from the late 18th century to the present day. In A Global History of Relocation in Counterinsurgency Warfare, Edward J Erickson brings together a distinguished cast of contributors to present a chronological survey of the major relocations of people conducted as deliberate operational approaches to modern conflicts.Each chapter covers a different case study, including the removal of Native Americans in the USA, La Reconcentracion in Cuba, the American internment of Filipinos after the Balangiga Massacre, the deportation of the Boer population in South Africa and the relocation of Ottoman Armenians and Russian Jews. Bringing together the threads of the separate case studies, the conclusion reaffirms relocation as a deliberate operational approach used by major powers in warfare against real or perceived threats. This is a vital volume for academics and students interested in military history, counterinsurgency and strategic studies.

The Global Nuclear Landscape: Energy, Non-proliferation and Disarmament


Like shifting sands of a desert, the global nuclear landscape changes every few years across its three main constituents - nuclear energy, non-proliferation and disarmament. Each of these has seen phases of cautious optimism, deep scepticism and outright pessimism over the last two decades. This book offers a bird’s eye view on all the three, even as the individual authors offer a worm’s eye view on each specific topic within the larger ambit. The first section of the book examines developments in the nuclear energy sector. A broad-brush scan of the contemporary drivers and challenges for nuclear energy at a global level, as also that of India, reveals a positive trend line. There is also cautious optimism around the concept, developments and prospects of small modular reactors. It remains to be seen how effectively and quikcly licensing and regulation issues are resolved for the new concepts to become commericially viable. The second part of the book is devoted to non-proliferation. Vertical nucluear and missile proliferation amongst nuclear armed states, and horizontal proliferation cases of Iran and possibilities in East Asia are considered. Nuclear terrorism and the state of the NPT are also examined. Collectively, these issues reflect a mood of pessimism on non-proliferation at this juncture. Neither is there much to cheer on nuclear disarmament. The last section of the book examines the consequences of use of nuclear weapons, concepts of CBMs and arms control, and recent disarmament initiatives. A tentative exploration of the prospects of disarmament in the wake of Russia-Ukraine conflict is also undertaken. A hope that good sense will prevail, and fear that it might not, seem to coexist at this moment. It is in India's interest to proactively shape the landscape across these three elements. The book seeks to provide the basis to do so.

Hearing the Crimean War: Wartime Sound and the Unmaking of Sense


What does sound, whether preserved or lost, tell us about nineteenth-century wartime? Hearing the Crimean War: Wartime Sound and the Unmaking of Sense pursues this question through the many territories affected by the Crimean War, including Britain, France, Turkey, Russia, Italy, Poland, Latvia, Dagestan, Chechnya, and Crimea. Examining the experience of listeners and the politics of archiving sound, it reveals the close interplay between nineteenth-century geographies of empire and the media through which wartime sounds became audible--or failed to do so. The volume explores the dynamics of sound both in violent encounters on the battlefield and in the experience of listeners far-removed from theaters of war, each essay interrogating the Crimean War's sonic archive in order to address a broad set of issues in musicology, ethnomusicology, literary studies, the history of the senses and sound studies.

Hitler and His Allies in World War Two


In an area where in-depth studies of Hitler's relations with Nazi Germany's allies, and the failure of Nazi Germany to make more effective use of them during the war, are scant, this is a survey that looks at the Soviet Union, Japan, France, Italy, Spain, Romania and Hungary and their relationship to Nazi Germany. Using a comparative approach, seven case studies examine themes such as co-operation and resistance, military and economic aid, treatment of Jews, relations with the enemies and the popular sentiment towards Germany. Jonathan Adelman has provided students of the Second World War with a welcome mine of information and a unique perspective on a much-studied topic.

Hitler's Geographies: The Spatialities of the Third Reich


Lebensraum: the entitlement of “legitimate” Germans to living space. Entfernung: the expulsion of “undesirables” to create empty space for German resettlement. During his thirteen years leading Germany, Hitler developed and made use of a number of powerful geostrategical concepts such as these in order to justify his imperialist expansion, exploitation, and genocide. As his twisted manifestation of spatial theory grew in Nazi ideology, it created a new and violent relationship between people and space in Germany and beyond. With Hitler’s Geographies, editors Paolo Giaccaria and Claudio Minca examine the variety of ways in which spatial theory evolved and was translated into real-world action under the Third Reich. They have gathered an outstanding collection by leading scholars, presenting key concepts and figures as well exploring the undeniable link between biopolitical power and spatial expansion and exclusion.

Holocaust Education Revisited: Orte der Vermittlung – Didaktik und Nachhaltigkeit (Holocaust Education – Historisches Lernen – Menschenrechtsbildung)

Jahrhundert sind die Fragen nach dem Warum, Wie und Wo von Holocaust Education neu zu stellen und vorliegender Band bietet Antworten darauf.

Hope Amidst Conflict: Philosophical and Psychological Explorations (Series in Political Psychology)


How does hope for peace form and proliferate in the seemingly hopeless reality of conflict, and why do despair and fear often prevail? How do political elites utilize hope and skepticism to manipulate their public during conflict? And how does hope manifest itself at the societal level? Hope Amidst Conflict takes on the bold challenge of answering these questions by merging insights from philosophy and social psychology and investigating hope for peace in an intense political context--the intractable, violent conflict between Israel and the Palestinians. Hope for peace has gathered scholarly attention in the last decade. However, the work has been focusing on the mechanisms of hope while failing to ask the bigger questions about hope's role in the politics of conflict. Moreover, existing research presents a confusing account of what hope "is" and how it can be measured. This confusion yielded mixed results regarding the levels and consequences of hope during conflict. Combining the wisdom of more than a hundred years of scholarship on hope with insights from original data collected in conflict zones, Hope Amidst Conflict offers a novel conceptualization of hope and a standardized way to measure hope in a wide array of contexts. Using these new approaches, the book embarks on a journey to identify the determinants and consequences of hope amidst conflict.

India, China and the Strategic Himalayas


This book analyses strategic discourse on the Himalayas from the perspective of India’s interests. Home to many communities, cultures, natural resources and political boundaries, it is the geopolitical landscape of the Himalayas between India and China that dominates other narratives and discourses. The traditional notion of Himalayas as India’s frontiers and buffer is challenged by China. Despite various mechanisms to address border resolution there are violations and transgressions from China. This book examines India’s responses to the new emerging challenges in the Himalayas. How the statist discourse on strategic interests incorporates people’s discourse. It provides a nuanced understanding of India’s strategic undertakings, diplomatic initiatives and development framework. This book will be a valuable addition to existing knowledge on the Himalayas between India and China. Scholars and practitioners interested in International Relations, Strategic Studies, Himalayan Studies and South Asian Studies will find it useful.

Intellectual Collaboration with the Third Reich: Treason or Reason? (Routledge Studies in Second World War History)


The book investigates the rather neglected "intellectual" collaboration between National Socialist Germany and other countries, including views on knowledge and politics among "pro-German" intellectuals, using a comparative approach. These moves were shaped by the Nazi system, which viewed scientific and cultural exchange as part and parcel of their cultural propaganda and policy. Positive views of the Hitler regime among intellectuals of all sorts were indicative of a broader discontent with democracy that, among other things, represented an alternative approach to modernization which was not limited to the German heartlands. This book draws together international experts in an analysis of right-wing Europe under Hitler; a study which has gained new resonance amidst the wave of European nationalism in the twenty-first century.

Internal combustion engine - Multipage image (Large Print)


These diagrams of an internal combustion engine are on two pages with two diagrams per page, separated by a vertical dotted line. There is a locator dot shown, which will be at the top left of the page when the image is the right way up. Each diagram is titled in the top left and shows a phase of the combustion engine cycle. In the top of each diagram from left to right there is an intake valve, a spark plug and an exhaust valve. In the centre of the image is the cylinder with the piston in its middle. This has a water cooling jacket to the left and right. The piston is connected by a connecting rod to the crankshaft and axle at the bottom of the image. Not all elements are labelled on every diagram. The valves and crankshaft are also in different positions. The crankshaft is continuously turning clockwise (with the top moving to the right) throughout all stages. In the first diagram fuel is being drawn into the cylinder through the open intake valve as the piston moves down. In the second diagram the intake valve has closed, the piston moves up and the air and fuel mixture is squashed. In the third diagram the air and fuel mixture has been ignited by a spark from the spark plug. The mixture burns and expands rapidly driving the piston down. In the last diagram the exhaust valve is open and the piston moves up driving the exhaust out of the cylinder. There are usually at least two cylinders which comprise the whole engine. They all drive the same crankshaft but are phased so that, for example, while one cylinder will be sucking air and fuel in, another will be burning the compressed mixture and generating the power.
