"Professor Chimène I. Keitner has fully revised and updated the late Professor Bederman‘s classic treatise, which offers a concise analytic guide to the historical evolution and contemporary intricacies of international law. Still incisive and irreverent, this book offers a highly readable yet nuanced text for university and law school students, as well as practitioners, researchers, and others who want to know what international law is and what it does in the twenty-first century. This fourth edition weaves in-depth considerations of key cases, core disputes, and essential international agreements into a broad overview of all important aspects of the subject. Readers will find an authoritative discussion of traditional topics such as the sources of international law and the methods of international dispute resolution alongside consideration of cutting-edge issues such as cyberwarfare, global migration, climate change, and the evolving law of jurisdiction and immunities in domestic courts." -- Back cover.
