Getting under a nuclear shield wouldn't be hard but having a strong alliance and acquiring ToT for the bomb as well as the delivery systems is very much possible, all we need is a prudent and shrewd leader.
No, either option would be next to impossible. The only countries that are not part of the NPT are India, Israel and Pakistan. Obviously, India and Israel aren't going to supply you with nukes so that leaves Pakistan. Could be a good option if Pakistan decides to forget about it's interests and do it just to irritate India. The economic consequences to them from the inevitable sanctions that will follow might make it a pretty hard for them to go down that path. I mean, who in their right mind would choose to destroy their economy for another country.
