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 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.
