You should know that the kalam is an aeronautical engineer. He was a respectable president and now respected ex president. but he is a fake nuke scientist. It is unethical to comment/ tell as like a nuclear scientist. he should have told sorry and told to ask nuke scientist. Nuke scientist will their own dreams about their profession in india. Please read Engineering Ethics principles. (book: Ethics In Engineering: Mike Martin, Roland Schinzinger TMH publication) It is very unfortunate to make such a comment on kalam. Professional society can punish him. no exited comment please before reading Engineering professional socitey code of conduct or the book
