I believe the necessity of conducting nuclear test will be eliminated in future due to the changes in geo-political happening around the subcontinent. Pakistan will slowly try to settle down and they wold be more focused on development than using nuclear bomb against India. China will not risk bombing India with nuclear weapon for any good reason. It is unthinkable that a country will be so foolish in the 21st century that it will use nuclear weapon against another country. That possibility is simply non-existent. Those who are showing the necessity of conducting nuclear test in future and hence opposing the deal are showing poor political judgment and their views based on more ideological inferences than reality.
