Buy

The essence of the defence minister's introspection was that ambiguity enhances deterrence. This view has been expressed by several nuclear strategists. Nuclear doctrines are not written in stone and are never absolutely rigid.

The New Arthashastra: A Security Strategy for India
Buy

For a country that has fought five wars and is hemmed in by nuclear-armed states, India surprisingly does not have a formally declared national security strategy.

Naxal Violence
Buy

The causative factor for the existence of the Naxal movement in India is ideological. Today, 196 districts are affected by it. Of these districts, 35 have been seriously impacted where the writ of the state is either weak or almost nonexistent. The spread of Naxalism is an indication of the sense of desperation and alienation that has swept across large sections of India.

Pakistan’s Tactical Nuclear Weapons
Buy

Tactical Nuclear Weapons (TNWs), often referred to as "battlefield," "sub-strategic," or "non-strategic" nuclear weapons, usually have a plutonium core and are typically distinct from strategic nuclear weapons. Therefore, they warrant a separate consideration in the realm of nuclear security.

Afghanistan A Role for India

The Af-Pak region is perceived as the base of global and regional terrorism, with the presence of international terrorist groups such as the Al Qaeda, Taliban, Lashkar-e-Taiyyaba, Jaish-e- Mohammad and other UN proscribed non-state actors as Jamaat-ud Dawa. Hence, stability in the Af-Pak region is of vital interest to India.

Future Wars ‘Changing Nature of Conflict’
Buy

India’s War on Terror

Kargil ’99: Blood, Guts and Firepower

For a country that has fought five wars and is hemmed in by nuclear-armed states, India surprisingly does not have a formally declared national security strategy. All the major powers of the world publish documents that spell out their national interests, identify their threats - political, economic, diplomatic or with regard to security - and draw up policies to deal with them.
