R P Singh asked: Can we define "minimum" in India's nuclear doctrine of minimum nuclear deterrence?

K. Subrahmanyam replies: The minimum deterrent should spread over three media, air, land and sea (under the sea). It should be sufficient to absorb a first strike by the adversary and then retaliate. It should be sufficient to deter two adversaries who have a nuclear proliferation relationship of over 34 years. This cannot be less than hundred but the optimum figure is a matter of strategic judgement.
