The nuclear bomb always was with india from the brave indira gandhi, who was the boldest of the prime ministers, india ever had, just think abt going for a nuc test at the time india was no more than another backward country from the third world, vajpayee took a step ahead and showed the world what we always had, the technology in place is that after the series of nuc test at vajpayees time the scientists had collected data, which they use to simulate the tests in super compueter environments, just as the US does, hence theres no need for india to go for expensive nuclezar tests, because we too are following the same simulation techniques !!
