India had almost 24 years to prepare, configure, execute and pre-analyze the nuclear tests before they carried out in 1998. Pakistan on the other hand had less than 30 days to really prepare tests and pre-analyze the results what ever they may be....idiotic minds only played by India cards !!! So, no matter what really was the technological success about the tests, India learnt a whole lot. Its doubtful if India is going to get anything better by conducting same tests again, so why bother. Unless of course, Paki-stan or China start conducting advanced versions of tests, which I think will be suicide in their own games against India, India does not need to start a whole lot of nothing. I think India played a wonderful game by conducting surprise tests in 1998 after waiting for so many years and caught all US, Pakistan and China napping. End result was that pakistant was and is still isolated and Pakistan's allies US and China are now gung-ho over India. Well played India.
