In this fourth edition of the book that has inspired the global justice movement, Geoffrey Robertson QC explains why we must hold political and military leaders accountable for genocide, torture and mass murder. He shows how human rights standards can be enforced against cruel governments, armies and multi-national corporations. This seminal work now contains a critical perspective on recent events, such as the changes in Egypt, Syria and Libya. Cautiously optimistic about ending impunity, but unsparingly critical of diplomats, politicians, lawyers and others who evade international rules, this book will provide further guidance to a movement which aims to make justice predominant in world affairs.
