This chapter concludes the book and considers its major theoretical and practical implications. It begins by exploring how the book pushes us to think about fake news and factual misperceptions as an important “layer” of war – a layer that has been largely neglected despite the burgeoning attention to these issues in other domains. This final chapter then examines what the book’s findings tell us about such topics as the psychology and behavior of civilian populations, the duration of armed conflicts, the feasibility of prevailing counterinsurgency models, and the depths and limits of misperceptions more broadly in social and political life. It also engages with the practical implications of the book for policymakers, journalists, activists, and ordinary politically engaged citizens in greater depth, exploring how the problems outlined in the research might also be their own solutions. Ultimately, this chapter shows how the book has something to offer to anyone who is interested in the dynamics of truth and falsehood in violent conflicts (and beyond) – and perhaps the beginnings of a framework for those who would like to cultivate more truth.

This chapter discusses the first level of contemplation, namely, psychic contemplation. The point of departure is Plotinus’ view of perception as a multi-level activity and his claim that we perceive external things by virtue of internal images. In the realm of affective experience, we also co-create our emotions rather than receive them passively. The fall is a distortion of the states of knowing (perceptions) and the states of loving (affects) as well as of the sense of the body, the world, and the self. In the first phases of contemplative ascent, virtues purify our experience of the self, and we begin to overcome the sense of the world as external and our emotional enslavement to it. The result is peace and freedom. The analysis of perception and affective experience shows that for Plotinus contemplation is a natural state of our soul. It is not adding something which is not there but recovering our awareness of what is already going on when we perceive experience affects or relate to our body.

This chapter presents latent nuclear deterrence theory. It explains how it is possible to gain international leverage from a nuclear program if countries do not have nuclear weapons.

This chapter marks the starting point of our investigation of actual policy solutions to tackle armed conflict. When a doctor has reached her diagnosis, she must then decide on the right medication to administer. Similarly, while economists started by studying the drivers of political violence, in recent years increasing efforts have been made to understand how to cut the Gordian knot of conflict. As argued in this chapter, a first-order factor is the institutional environment, and in particular the need to give a voice to all citizens and groups in society. Democracy is desirable, but without proper safeguards it can have a dark side and result in blood being spilt. Furthermore, the type of democracy and the provisions of sharing power between groups matter. Closer inspection of local-level power-sharing in Northern Ireland, the building of modern Switzerland after its civil war in 1847, the difficulties for current democratization in Iraq and the franchise extension during the British Age of Reform drive this discussion forward.

This chapter discusses the impact of particular policies at the global level. It turns out that coordination and common standards can make a big difference. First, it is shown that the global traceability of minerals can cut rebel funding significantly. Next, the role of monitoring multinationals is highlighted. Notably, recent studies have pinpointed the importance of corporate social responsibility of mining firms, revealing that the best-run mineral extractors may have a beneficial impact on the local population, while poorly run firms yield disastrous outcomes. Further, given that wars tend to trigger a series of vicious cycles, there is a powerful case for facilitating refugee admission. It is discussed how a well-coordinated refugee policy can reduce violence perpetuation over future generations. Next, we investigate what role international trade can play for fostering peace and what harmful effects arms trade can entail. It is shown how arms-producing countries can – without bearing large economic costs – reduce the ability of bad regimes to attack their civilians. Finally, the importance of a rule-based international order and a well-managed green transition is highlighted.

This chapter stresses the importance of smart idealism, and outlines how global public opinion – and all of us – can play a crucial role. We cannot simply rely on our politicians to “do the right thing,” as either of the two components of smart idealism may be missing. Ideological bias may result in policies falling short of being smart or failing to be idealist, namely when politicians’ incentives are distorted. Electoral terms typically of four years result in a bias towards short-run policies (at the detriment of the lengthy, but crucial task of building peace), and often there are personal benefits for politician when cutting shady deals with despots. To get the incentives right, public pressure must ensure that the reelection chances of our politicians crucially depend on fostering peace at home and abroad. If voters care about this, then politicians will as well – whether out of intrinsic motivation or just to get reelected. As shown in this chapter, recent evidence highlights that scrutiny and attention from the world press and the public at large is a powerful rampart against repression.

The concluding chapter wraps up the various arguments and pieces of evidence presented in this book in favor of our peace formula. Overall, the first take-home message to be highlighted is the need for smart idealism – as neither the cold-hearted egotist nor the naïve idealist will be able to curb conflict. Secondly, it is again stressed which concrete policies are key to making a difference, creating a synthesis of the various points of the previous chapters. In particular, we emphasize the key role of a democratic voice, security warranties, promoting productive work, fostering trust and reconciliation, accelerating a well-managed green energy transition and stepping up international coordination across a variety of issues. The final point is that since we are all affected by conflict, we should all be part of the solution. It turns out that several studies have found that pressure from the public opinion matters, both in the implementation of policies and in preventing atrocities. There is a job to be done, so let us work together to make a change.

This chapter argues that building strong institutions and a productive economy in the aftermath of conflict is not enough and that rebuilding lost social capital and trust is of paramount importance. Intergroup trust matters deeply, as the same formal institutions can have divergent effects in different social structures and for different levels of social capital. Starting from the so-called contact hypothesis that fostering positive intergroup interaction builds trust, it is argued that reconciliation and the rebuilding of social trust are also part of the promising blend of propeace policies. A variety of empirical studies are discussed, ranging from reconciliation efforts in Rwanda and Sierra Leone to programs fostering intergroup contacts in Spain, Nigeria, India and Iraq. While we find that more intense group contacts deploy typically desirable effects, trying to achieve reconciliation by altering beliefs through media campaigns is a double-edged sword that involves a series of dangers. We conclude this chapter by stressing the key role of stepping up critical thinking.

As shown in this chapter, state capacity and security warranties are further key factors in the peace formula. In particular, besides certain institutional features, the overall strength of the state is a major determinant of political stability, as illustrated by examples and recent research on Iraq, Somalia, Niger and the origins of the Mafia in southern Italy. Drawing on cutting-edge studies, it is argued that being feared (by extremist groups) may be more important than being loved (by the population at large). In order to win the hearts and minds of the population, it is essential that first public safety is guaranteed and that basic services are delivered efficiently. This is easier said than done. It is shown that when foreign military aid aims at capacity building, it often backfires. In contrast, UN peacekeeping troops have been demonstrated to play a key role. We end this chapter by emphasizing the several domestic factors that can help the building of lasting state capacity, with a special emphasis on well-designed welfare programs such as Franklin D. Roosevelt’s New Deal.

This chapter starts off by explaining that we are in the midst of a critical historical juncture with a record number of wars and conflicts around the world, calling for urgent action. Next, we discuss in depth three common but disastrous misconceptions, namely that shady deals leaving autocrats in power can bring peace, that “buying” peace through simple cash transfers works, and that charm offensives and communication efforts suffice to do the job. Drawing on a number of examples, the book highlights the pitfalls of these common misconceptions before turning to success stories. Illustrated by examples of the successful postwar reconstruction of Germany and Japan, the fall of apartheid in South Africa and democratization of Uruguay, Chile and Peru, the chapter then formulates the key components of what is called the peace formula – a set of key policies that constitute crucial ingredients for a successful and lasting pacification process. Finally, it is stressed that to counter distorted incentives for peace we need smart idealism – pairing good intentions with evidence-based policy knowledge.

This chapter shows that a series of public policies have the potential to boost citizens’ perspectives for finding work and thereby foster incentives for peace. The first prominent policy is to invest in education. A more educated population generates countless benefits, one of which is the prospect of obtaining better jobs. Fundamentally, more meaningful employment raises the opportunity cost of giving up paid work to join an armed rebellion. Furthermore, physical capital (money) can more easily be stolen than human capital (knowledge). Hence, investing cash in building classrooms means that trying to topple the state will become less lucrative. Next, it is spelled out how better health leads to both a longer time horizon and a higher opportunity cost of conflict. This, in turn, makes long-run (peaceful) investments more appealing and reduces the scope for short-term appropriation and looting. Finally, a series of labor market policies are assessed, stressing the role of good jobs in making it less attractive to leave work and go to war. Empirical evidence from a variety of contexts is presented.

This chapter provides a brief introduction to the ethics and laws of war. The first part outlines what international law and the ‘just war’ tradition say about war; the second explores the conduct of war; and the third examines two recent dilemmas as examples of moral and legal debate: the legitimacy of pre-emptive self-defence and the use of cluster bombs.

The Cold War was the most important feature of the international system in the second half of the twentieth century. The rivalry between the Soviet Union and the United States shaped the contours of conflict and cooperation among states and peoples between 1945 and 1991 and its dynamics permeated almost all corners of the globe. Whether in Baghdad, Bangkok or Brussels, the influence of geopolitical and ideological conflict was unmistakable. The Cold War created rivalries and political faultlines that have continued to shape international relations years after its passing. Sino-American competition has become so intense that many think the world is on the brink of another period of bipolar rivalry.

The discipline of International Relations owes its origins to the study of war and peace. But are today’s wars so different from their predecessors that we need a new mindset? To answer that question, this chapter begins with warfare’s diverse ends and means before considering five leading issues: the role of violence in warfare; the extent to which that violence is organised; the political nature of war; the interactive nature of warfare; and the scope and scale of war. The argument presented here is that war’s essential features have not changed as much as we might think. This should make us sceptical about claims that the role of war in international relations has somehow been revolutionised.
