1. Introduction

Nuclear pacifists categorically reject nuclear weapons on ethical grounds. This volume aims to prolong the ideas behind this particular tradition of thought that we would like to brandish as non-nuclear peace. The Nuclear Ban Treaty (2017) shows the impatience by the majority of states in the world with respect to the implementation of the legal promise of getting rid of nuclear weapons, made by the five formal nuclear weapon states in the Nuclear Non-Proliferation Treaty (NPT). Regardless of the impact of the Ban Treaty, it is useful to start thinking about the next phase, namely how to imagine non-nuclear peace in light of contemporary and future global political and cultural conditions, and how to reach and sustain a peaceful order without nuclear weapons.
