Pakistan faces serious internal security challenges in form of communal, sectarian, political, ethno-nationalist, lslamist divide and violence as well as ever increasing terrorist and insurgent attacks. Most of these internal security challenges stem from ideology of Pakistan and the state's failure to develop an inclusive form of nationalism. Moreover, Pakistan's insistence of using lslamist groups as levers of its foreign and security policy has further complicated the security environment of the nation. The policy of nurturing some militant groups as assets and eliminate those who fight the state has failed. Over the years it has created a society where these militant groups have spread their tentacles and are now well entrenched. How far will the Armed forces be able to overcome the Internal Security Challenges will depend upon a great deal on its intention, capability and method adopted. This book is an attempt to understand the various security challenges being faced by Pakistan and the ability of its Army to overcome them.
