Pakistan is not going to give up this program at any cost, any cost. World has tried for 30 years and always failed. This included direct and indirect warnings/threats/pressure and even direct attack, twice, by India and Israel, yet they always failed. We have and we shall always stick to this program of us, without which, Pakistan would not have been present today. This program is a pain for everyone who dares look at Pakistan as enemy, and hence it's not surprising that they will try all means for Pakistan to surrender her Nuclear program. Plans of joint-direct attacks did nothing, neither would whines or propaganda.
