Merely by peddling Kalam's credentials, the UPA cannot get a certificate on the Nuclear deal. Kalam may be a brilliant nuclear scientist. But this issue is about the hidden clauses of the Nuclear Agreement, which is an International Treaty. How many International agreements would Kalam have gone through to be called an expert on this subject?
The fact remains that if we ever decide to conduct more nuclear tests, we have to give back all the benefits that we have got from this deal. Since this would be next to impossible, our hands will be tied if we ever want to further develop the Nuclear weapons program, while Pakistan and China will be free to carry out any number of tests!
