ProudNorth, Your speculation is okay to make. But magazines in the West and the Institute of Strategic Studies in London, believe that both India and Pakistan have "basic atom bombs" = using uranium isotope and conventional triggers. But no "hydrogen" bombs yet. They credit India with about 220 "deliverable" weapons and Pak with about 100. Perhaps, they are also speculating, although they may have sources in their intelligence services. That is, however, current wisdom. 1. I agree with your speculation that the underground tests may NOT have been a total success for the two countries. 2. After India's test, there was some speculation whether further "verification" and "confirmation" could be had via "computer generated simulation exercises". Some codes India was still looking for. So, you may be right that Indian scientists did not go home fully satisfied. BJP now says, they would agree to the "Indo-U.S Deal" if India could test further, perhaps, about two or three times only. 3. After Pak. announced its "test", European and Japanese seismologists said, "they detected no sign that Pak had tested". Then the US scientists, said there had been a Pak test of "low intensity" (= whether it was a conventional rather than atomic explosion?). A.Q. Khan was qualified enough to put together a test. 4. In the changed scenario in the world, who knows, whether India may be getting the "Codes" for "testing" with the computer. No need for actual tests. Israel may be helping.
