Sir: The nuclear tests by India may not be welcomed by nuclear weapons states, but they do answer India's security concerns. India does not need nuclear weapons to counter Pakistan. The real threat is from China. It is unlikely the US or the UK will come to India's aid in case of a war with China.
Instead of condemning India, it would be prudent to enter into a constructive dialogue so that the Indian authorities can prevent fissile material from falling into rogue hands, maintain the nuclear reactors properly (to prevent a fallout) and safely dispose of nuclear wastes.
