A ban on nuclear weapon research is needed, but virtually impossible to implement. I have seen homeless, hungry people living on the streets of London and New York. With no progress towards disarmament, and threats all around, India had no choice. How can any other nuclear power, which has perfected these weapons with a far greater number of tests, condemn a country so isolated in its security concerns. India can no longer be treated as a pariah on issues of international security.
True disarmament is possible only if all the nuclear weaponss are destroyed, the world over.
Now these nations want India to stop the testing and development of nuclear weapons, while they still stockpile nuclear weapons. It is only fair that India has decided to take this decisive step towards protecting its citizens. India does not claim to be an aggressor, but merely wants to be sure that it is capable of defending itself, something that is surely the right of every sovereign state. India has been living in sanctions for quite some time. It isn't something new.
