On related matters there is an interesting article [and cover story] in the February Physics Today, Pakistan’s nuclear Taj Mahal by Stuart W. Leslie
Inspired by the promise of Atoms for Peace, the Pakistan Institute of Nuclear Science and Technology eventually succumbed to the demands of the country’s nuclear weapons program.One thing I learnt was the central role that Abdus Salam played. I found the following rather disturbing.
Salam, though still the director of the ICTP, organized the theoretical-physics group that performed the sophisticated calculations for the bomb, and he personally asked his former student and protégé Riazuddin to head it. Riazuddin, then teaching at the University of Islamabad (now Quaid-i-Azam University), took several trips to the US, where he collected unclassified documents on nuclear weapons design. .... Salam left the details to others, though he did open the ICTP library to Riazuddin’s group and kept in close touch with its members. Riazuddin, describing his research team, later acknowledged, “We were the designers of the bomb.... ”A thoughtful and careful analysis of the implications of India and Pakistan obtaining nuclear weapons was given in 2000 by Amartya Sen.
