The september 11 attacks have been taken as system-level development in this book. The terrorist attacks have produced important conclusions. The discussions on a number of issues in this direction also pave way for understanding the changing dynamics of world politics. We offer contending analyses under the common thematic preference of September 11 and World Politics. This book consists of the theoretical and empirical chapters on the impact of September 11 on World politics and International Law; the analyses of the U.S. attack on Afganistan; the international and regional dimension on the Muslim World at both intellectual and common levels.
