This book seeks to understand how and why we should hold leaders responsible for the collective mass atrocities that are committed in times of conflict. It attempts to untangle the debates on modes of liability in international criminal law (ICL) that have become truly complex over the last twenty years, and to provide a way to identify the most appropriate model for leadership liability. A unique comparative theory of ICL is offered, which clarifies the way in which ICL develops as a patchwork of different domestic criminal law notions. This theory forms the basis for the comparison of some influential domestic criminal law systems, with a view to understanding the policy and cultural reasons for their differences. There is a particular focus on the background of the German law which has influenced the International Criminal Court so much recently. This helps to understand, and seek a solution to, the current impasses in the debates on which model of liability should be applied. An entire chapter of the book is devoted to considering why leaders should be held responsible for crimes committed by their subordinates, from legal, moral and pragmatic perspectives. The moral responsibility of leaders is translated into criminal liability, and the different domestic models of liability are translated to the international context, in such a way as to appeal to advanced students of ICL, academics, and practitioners who want to understand the complexities of leadership liability in international criminal law today and identify the best way to approach it.

Greater participation by women in peace negotiations, policy-making, and legal decision-making would have a lasting impact on conflict resolution, development, and the maintenance of peace in post-conflict zones. Women, Peace, and Security lays the groundwork for this enhanced participation, drawing from insightful research by women scholars and applying a feminist lens to contemporary security issues. This timely collection of essays promotes the adoption of a feminist framework for international security issues and presents the voices of some of the most inspiring thinkers in feminist international relations in Canada. Women, Peace, and Security provides insightful recommendations to researchers conducting fieldwork, as well as methodological insights on how to develop feminist research design in international relations and how to adopt feminist ethical considerations. Contributions include gender-based analyses of the challenges faced by the Canadian military and by families of serving members. From Canada's Famous Five to the women's marches of 2017, lessons are drawn to inform new generations of women activists, concluding with a clarion call for greater allyship with Indigenous women and girls to support decolonization efforts in Canada. Offering a unique range of perspectives, narratives, and contributions to international relations and international law, this volume brings women's voices to the forefront of vital conversations about fundamental peace and security challenges.
