This new edition of Cassese's International Law provides a stimulating account of International Law for undergraduates and postgraduates. It has been fully revised and updated to include all recent developments in the subject, and contains a new chapter on terrorism as well as extensive revision of the section on state responsibility. Providing a commentary on International Law as a whole, it compares the traditional legal position with the developing and evolving law in a way that is sensitive to political and economic considerations, as well as including detailed yet accessible examinations of State Responsibility and international criminal law. Professor Cassese is the Editor of the Journal of International Criminal Justice.
