This paper attempts to compile nuclear events, including weapon use and tests as well as debates surrounding nuclear winter. It also briefly discusses these devastating environmental effects in the light of a hypothetical nuclear war between two South Asian nuclear neighbours.

Infectious disease and related health concerns have rarely found a place in the national security discourse in the past. Of late, the issue has assumed prominence and managed to enter into the national security debate. Disease spread poses a threat to human security and national security.

In absence of a national security strategy (NSS), the task of intelligence agencies in India has failed to be systemic. India’s intelligence infrastructure lacks a holistic view and very less effort has been put to reorganize intelligence infrastructure on the basis of contemporary threat perceptions. Without a strong security infrastructure country cannot eye towards becoming a regional power. Due to a rigid security system, India has a disparate intelligence mechanism in service. While little effort has gone towards synergizing all sources of intelligence and request dissemination in real time/ near real time basis. This paper attempts to outline a number of points, which would help to develop a more superior external intelligence infrastructure.

• Defence budget cannot be stretched beyond a point, which means Defence Minister Manohar Parrikar has a tough choice for resources deployment.
• Reducing revenue expenses and more spending for capital purchases pose the biggest challenge for Indian MoD
• National defence budget is all about ‘revenue’ side of armed forces and their ‘capital’ requirements. But, is India spending adequately on defence R&D?
• National Defence Budget must be reasonably used to get maximum value for the state and its preparedness.

The threat of chemical and biological terrorism emanating from non-state actors, including the Islamic Jihadi organisations, which control large swathes of territories and resources, remains a major concern for nation states today. Over the years, the capability and intentions of Islamic jihadist groups have changed. They evidently prefer for more destructive and spectacular methods. This can be very well argued that if these weapons systems, materials or technologies were made available to them, they probably would use it against their enemy to maximize the impact and fear factor.

Once the negotiations for FMCT start, a window of opportunity would open up for the Conference on Disarmament to develop a legally binding mechanism to eliminate fissile material and nuclear weapons from the face of the earth, attaining the objective of universal and comprehensive disarmament.
