Rejecting doubts raised by some scientists over India's nuclear deterrence, DRDO chief V K Saraswat on Tuesday said the country is "self-sufficient" and has the capabilities it "needs to have".
"In terms of deterrence, India has the capability, which it needs to have. Any deterrence is the function of what is the threat against which you are creating it and in that particular aspect, we are totally self-sufficient," he told reporters on the sidelines of a DRDO seminar in New Delhi.
Saraswat was asked about the effectiveness of India's nuclear deterrence after doubts raised over it by nuclear scientists K Santhanam and P K Iyengar.
"In terms of capability, what matters is the efficacy of your deterrence and not the numbers. I can assure you that in terms of efficacy, we are at par with whatever adversaries we are looking at," he added.
Saraswat said India's deterrence capabilities were fully safe and all the infrastructure required was also in place.
