Coercion moves beyond these somewhat hidebound premises and examines the critical issue of coercion in the 21st century, with a particular focus on new actors, strategies and objectives in this very old bargaining game. The chapters in this volume examine intra-state, inter-state, and transnational coercion and deterrence as well as both military and non-military instruments of persuasion, thus expanding our understanding of coercion for conflict in the 21st century.
