Four decades have passed since India conducted its first nuclear test. Since then the world has undergone a transition, both in terms of power dynamics and military warfare. The emergence of New Nuclear and Threshold states has transformed the traditional military warfare, making it more asymmetric.

India which is also emerging as a powerful state needs to approach this dynamic shift in a holistic manner. A strategic churning has begun in Asia and whether this will be in India's favor depends on the strategic choices that India adopts.

Pakistan through its nuclear policy of "First Use, ." its alleged use of "Tactical Nuclear Weapons" is making South Asia vulnerable to nuclear terrorism. Under such conditions are there any gaps between India's nuclear doctrine and its force structure? Can India's nuclear strategy counter China? Is India capable of countering a Sino-Pak nexus?
