Who told u that Pakis tested weapon after India did so? Pakis had a tried and tested Chinese design as well as ready made bomb on that design. They only exploded them after India tested the design developd by Indian scientists. Do u think nuclear bombs can be set up in 2 days? They cannot even be assembled in 2 days time. Dont b naive. As India knew about existence of Pak bomb testing our own design had become imperative.
