when did Pakistan nuclear capability become operational? we did have missiles before that; how much time it took us to convert them to be able to carry nuclear warhead

What about India?? It also carried out such blasts!!

Although India first tested a nuclear explosive in 1974 (euphemistically called the PNE, for "peaceful nuclear explosive") it did not become a nuclear weapons state - in the sense of having the ability to deliver nuclear weapons until 1986-88 when, according to Dr. Sanjay Badri-Maharaj author of The Armageddon Factor, a rudimentary delivery system was in place [Indian Express, 18 June 2000]. This presumably refers to a developmental delivery system based on the Mirage 2000 that began development in 1986, after an attempt to integrate a DRDO developed nuclear bomb with the Jaguar fighter-bomber failed. This system provided India with a usable but limited nuclear weapons capability, but the weapon system did not actually enter service until it passed a full field drop test in May 1994 at Balasore, though most observers thought that this milestone had been passed years before.
