This Element tries to answer three questions about Kant's guarantee thesis by examining the 'first addendum' of his Philosophical Sketch; how the guarantor powers interrelate, how there can be a guarantee without undermining freedom, why there is a guarantee in the first place. Kant's conception of an interplay of human and divine rational agency encompassing nature is crucial: on moral grounds, we are warranted to believe the 'world author' knew that if he brought about the world, the 'supreme' good would come about too. Perpetual peace is the condition enabling the supreme good to be realized in history.

Violent conflicts today are complex and increasingly protracted, involving more nonstate groups and regional and international actors. It is estimated that by 2030—the horizon set by the international community for achieving the Sustainable Development Goals—more than half of the world’s poor will be living in countries affected by high levels of violence. Information and communication technology, population movements, and climate change are also creating shared risks that must be managed at both national and international levels. Pathways for Peace is a joint United Nations†“World Bank Group study that originates from the conviction that the international community’s attention must urgently be refocused on prevention. A scaled-up system for preventive action would save between US$5 billion and US$70 billion per year, which could be reinvested in reducing poverty and improving the well-being of populations. The study aims to improve the way in which domestic development processes interact with security, diplomacy, mediation, and other efforts to prevent conflicts from becoming violent. It stresses the importance of grievances related to exclusion—from access to power, natural resources, security and justice, for example—that are at the root of many violent conflicts today. Based on a review of cases in which prevention has been successful, the study makes recommendations for countries facing emerging risks of violent conflict as well as for the international community. Development policies and programs must be a core part of preventive efforts; when risks are high or building up, inclusive solutions through dialogue, adapted macroeconomic policies, institutional reform, and redistributive policies are required. Inclusion is key, and preventive action needs to adopt a more people-centered approach that includes mainstreaming citizen engagement. Enhancing the participation of women and youth in decision making is fundamental to sustaining peace, as well as long-term policies to address the aspirations of women and young people.

Peter Yearwood reconsiders the League of Nations, not as an attempt to realize an idea but as an element in the day-to-day conduct of Britain's foreign policy and domestic politics during the period 1914-25. He challenges the usual view that London reluctantly adopted the idea in response to pressure from Woodrow Wilson and from domestic public opinion, and that it was particularly wary of ideas of collective security. Instead he examines how London actively promoted the idea to manage Anglo-American relations in war and to provide the context for an enduring hegemonic partnership. The book breaks new ground in examining how London tried to use the League in the crises of the early 1920s: Armenia, Persia, Vilna, Upper Silesia, Albania, and Corfu. It shows how in the negotiations leading to the Draft Treaty of Mutual Assistance, the Geneva Protocol, and the Locarno accords, Robert Cecil, Ramsay MacDonald, and Austen Chamberlain tried to solve the Franco-German security question through the League. This involves a re-examination of how these leaders tried to use the League as an issue in British domestic politics and why it emerged as central to British foreign policy. Based on extensive, detailed archival research, this book provides a new and authoritative account of a largely misunderstood topic.

An informed modern plan for post-2020 American foreign policy that avoids the opposing dangers of retrenchment and overextension Russia and China are both believed to have "grand strategies"--detailed sets of national security goals backed by means, and plans, to pursue them. In the United States, policy makers have tried to articulate similar concepts but have failed to reach a widespread consensus since the Cold War ended. While the United States has been the world's prominent superpower for over a generation, much American thinking has oscillated between the extremes of isolationist agendas versus interventionist and overly assertive ones. Drawing on historical precedents and weighing issues such as Russia's resurgence, China's great rise, North Korea's nuclear machinations, and Middle East turmoil, Michael O'Hanlon presents a well-researched, ethically sound, and politically viable vision for American national security policy. He also proposes complementing the Pentagon's set of "4+1" pre-existing threats with a new "4+1" biological, nuclear, digital, climatic, and internal dangers.

John Maynard Keynes, then a rising young economist, participated in the Paris Peace Conference in 1919 as chief representative of the British Treasury and advisor to Prime Minister David Lloyd George. He resigned after desperately trying and failing to reduce the huge demands for reparations being made on Germany. The Economic Consequences of the Peace is Keynes' brilliant and prophetic analysis of the effects that the peace treaty would have both on Germany and, even more fatefully, the world.

Timely and pathbreaking, Securing the Peace is the first book to explore the complete spectrum of civil war terminations, including negotiated settlements, military victories by governments and rebels, and stalemates and ceasefires. Examining the outcomes of all civil war terminations since 1940, Monica Toft develops a general theory of postwar stability, showing how third-party guarantees may not be the best option. She demonstrates that thorough security-sector reform plays a critical role in establishing peace over the long term. Much of the thinking in this area has centered on third parties presiding over the maintenance of negotiated settlements, but the problem with this focus is that fewer than a quarter of recent civil wars have ended this way. Furthermore, these settlements have been precarious, often resulting in a recurrence of war. Toft finds that military victory, especially victory by rebels, lends itself to a more durable peace. She argues for the importance of the security sector--the police and military--and explains that victories are more stable when governments can maintain order. Toft presents statistical evaluations and in-depth case studies that include El Salvador, Sudan, and Uganda to reveal that where the security sector remains robust, stability and democracy are likely to follow. An original and thoughtful reassessment of civil war terminations, Securing the Peace will interest all those concerned about resolving our world's most pressing conflicts.
