I have wondered about this: Does nuclear weapon technology eventually reach a saturation point, where there is not much more you can do in terms of weaponization and yield, etc ?? The implication of this is that eventually all the nuclear weapon states would have similar capabilities, and there is nothing more you can do to improve your arsenal, or even if there is.....its very minor advances. If that is the case, then eventually all the nuclear weapons states would reach a level of parity in terms of nuke capability provided they have proven delivery systems. One would assume that the US and Russia, France, GB, and maybe China are already there. This means that India could also be there in another 10 years after their delivery systems are perfected ??
