Grawemeyer Award winner Kathryn Sikkink offers a landmark argument for human rights prosecutions as a powerful political tool. She shows how, in just three decades, state leaders in Latin America, Europe, and Africa have lost their immunity from any accountability for their human rights violations, becoming the subjects of highly publicized trials resulting in severe consequences. This shift is affecting the behavior of political leaders worldwide and may change the face of global politics as we know it. Drawing on extensive research and illuminating personal experience, Sikkink reveals how the stunning emergence of human rights prosecutions has come about; what effect it has had on democracy, conflict, and repression; and what it means for leaders and citizens everywhere, from Uruguay to the United States. The Justice Cascade is a vital read for anyone interested in the future of world politics and human rights.
