the quantity is good thing, but quality is necessary too. Now that Pakistan is quickly becoming the 4th largest nuclear power, Pakistan need to work tirelessly on miniaturisation and develop state of the art smaller weapons, this reduces the quantity of enriched uranium and plutonium needed for the weapons. It would mean more weapons deployed and fired from various platforms including submarines and artillery pieces.
Work on better guidance systems.
And yeah, learn from Indians to how to produce "indigenous" weapons, without the help of other countries. Spend 30 to 40 years, over budget, over weight, obsolete weapons and then wait for the missile failures. This is a precious art, one has to learn and master like it is mastered by DRDO. Without it your experience and products would count for nothing.
Also learn how to conduct a failed nuclear test. The actual nuclear material failed to go off, and the blast only lit the fuse.
Without these traits, Pakistan is a fake Nuclear State, and would not be recognised at all.
