No, Pakistan managed to work out an alternative to enrich uranium to weapons grade. & they've built, tested & deployed nuke weapons. While their country seems to be a trainwreck otherwise, their nuke industry has worked well.
I don't think they have much of a nuke industry. North Korea wants to make and sell nukes, but Pakistan basically has six nukes (so I read) that they are keeping under uncertain guard and when their country does fall totally apart, I guess securing (removing) them will be yet ANOTHER job for our SEALS.
I don't know why you say they have "deployed" nukes? Deploying nukes would be, you know, conspicuous what with the mushroom cloud and the seismic record.
