This edited volume provides a fresh analysis for researcher and practitioners regarding United Nations Security Council resolution 1540, the status of its implementation, and its future by providing an original evaluation of progress in implementation and challenges faced during the resolution first decade. In doing so, the book will consider the resolution utility as a non-proliferation tool with a view to identifying what further actions are required for the objectives and goals embodied by UNSCR 1540 to be achieved and sustained.  The book progresses by exploring the history of the resolution, implementation trends, implementation from a regional perspective, challenges, and future ways forward. The book appeals to a wide readership of scholars, policymakers, and other stakeholders of the 1540 process.
