Actually, I think, along with nuclear weapons, India should also clandestinely develop chemical and biological weapons (if it has not already done so), since they too come under weapons of mass destruction category. These guys are also relatively easier to get. And may be, there needs to be a deliberate "leak" that India has such weapons in Good numbers, along with delivery systems, so as to deter the Chinese. Of course, officially we can always deny that we have such weapons. By the way, dump all the treaties on chemical weapons or biological weapons into the Ganga. Genuine concerns of National security take precedence over such things.
