The states of West Asia continue to grapple with dramatic changes taking place in the domestic and regional environment. Security has emerged as a significant concern for them. The political upheavals, civil strife, sectarian violence and terrorism in the area have implications for the regional and global order. As the region grapples with myriad socio-economic problems, many extra-regional players and non-state actors, and a few regional ones, are attempting to carve out their own areas of influence. These developments across West Asia demand constant monitoring and careful analyses. This book is a collection of essays exploring various aspects of the changing security paradigm in West Asia and the regional and international responses.
