New Delhi–The Uri attack that killed 19 Indian Army soldiers and the subsequent “surgical strikes” across the Line of Control (LoC) that took out an estimated 35-40 militants has seen the ratcheting up of dangerous rhetoric on both sides of the border.

As the din of those rooting for war reached a crescendo, Pakistan’s Defence Minister Khawaja Muhammad Asif even threatened to unleash tactical nuclear weapons on India. How portentous is the threat? What does “tactical” mean when used in the same breath as nuclear weapons?

In an email interview with IANS, Pervez Hoodbhoy, the Karachi-based nuclear physicist, who is a champion of freedom of expression, answers questions with “surgical” precision. He teaches physics and mathematics in Lahore. He was voted 85th in a list of 100 public intellectuals from around the globe by ‘Foreign Policy’ magazine in 2011. Excerpts from the interview:

Q: What is the difference between tactical and strategic nuclear weapons?

A: Tactical weapons generally have smaller yields and can be launched from trucks armed with multiple rocket barrels. These have ranges that do not exceed 100km. Strategic weapons can be aircraft or missile delivered to any place on the subcontinent.

Q: Under what circumstances is Pakistan likely to deploy and use its tactical nuclear weapons?

A: Pakistan has always said that its tactical nuclear weapons exist to thwart a major Indian land invasion or sea blockade. However, I suppose that there must be planning for other contingencies as well.

Q: How much damage can they cause in comparison to strategic nuclear weapons?

A: Both can inflict a huge amount of damage depending upon where they are used. There is no clear distinction between strategic and tactical weapons. If used against a military target, the warhead is called tactical. But when used against a population centre, dam or industrial site, it is called strategic.

Q: What is the likelihood of the use of a tactical nuclear weapon escalating into a full-blown nuclear war?

A: The use of a nuclear weapon against any kind of target signals that a nuclear war has started. The chances are that if one is used, there will be a retaliatory strike. Escalation is very likely, to the point that war may end only when all weapons have been used up.

Q: Can the use of nuclear weapons ever be justified, however low-intensity? In the context of Indo-Pakistan hostilities, have they been a deterrent?

A: People need to understand that the use of a single nuclear weapon, even if small in size, is breaking a deep taboo. Once broken, all bets are off because anything can happen after that. While it is clear that nuclear weapons have prevented India from using its larger conventional might against Pakistan, they have allowed Pakistan to take a much more aggressive position against India. I had argued with the late K. Subrahmanyam (a strategic affairs analyst and an early shaper of Indian nuclear policy) on this point repeatedly 20 years ago, but he had dismissed the possibility of Pakistan achieving bomb status.

Q: As a rational voice from across the border, who do you think has been the “aggressor” of the two countries? Do you see any weight in India’s claim of being a victim of Pakistan’s proxy wars?

A: People like me have long argued that Pakistan has used the nuclear umbrella to protect groups such as Lashkar-e-Toiba. This is an abominable fact. Under no circumstances should Pakistan shelter or aid those who kill and murder, whether the victims be Indians or Pakistanis. At the same time, I am dismayed by the hard line India is taking on Kashmir. It could push us into even more difficult times.

Q: What steps should the governments take to de-escalate?

A: It is crucial to limit the rhetoric and desist from inflaming the situation on the LoC. Else, no one can predict where things might go.



  1. in the article “All bets are off, if even one n-bomb is used: Pak N-physicist Pervez Hoodbhoy”, the interviewer Vishal Narayan does a fine job. Until, that is, he tries to do the usual India Is Right At All Times bit. There was absolutely NO need to put Mr. Hoodbhoy on the spot by asking him who was the agressor. This was not the interview in which to ask that question — if there EVER is such a forum. Such patriotic thinking is what has led most of the world to the precarious precipice it’s teetering on the edge of since the dawn of the Nuclear Age
