The point is not whether other countries got some tech from other countries or not. There are two more important Q's. Does Pak have the scientific and technological manpower to contribute anything substantial or even to sustain their programs. From all accounts, NO! They cant even make a gun let alone a missile launcher. That brings me to the next Q. If not how do they keep shooting missiles and exploding bombs? The answer is most revealing -China. The chinese armed and continue to arm Pak to keep India unsettled. Pak gets a steady support from China to sustain and improve their program without which they would be nowhere. No doubt the US has helped for example by Carter and Reagan looking the other way when reports started coming in of Pak being close to the bomb and of China's involvement. India knew it too from hair samples obtained from near their nuke facility. But even the US did not help Pak in that limited way to harm India - But China is doing that.
Most other countries including India have enormous expertise unlike Pak and even if all of them got some tech here and there they are very different from Pak which is sinking. What can you expect from a largely Madrassa-based education that leaves out Science and tech and concentrates on abolishing thought.
