If we are to test a N-bomb again we are we aiming it for - who is India's enemy - Pakistan? China? or the US? India doesnot need a N-bomb to tackle Pakistan. China it is not their diplomacy to use nukes against India. US: India will never dare to fight against them. Instead of putting millions of money into testing a nuclear device - eradicate the poverty of million Indians. fight the in-fighting, the hatred between various communities. Improve the economy. Let there be a homogenous development withour concentrating investments in metros and mini metros. Flush out funds to smaller towns and villages. use nuclear energy for peaceful means - look how japan/ australia are doing it... emulate them.
