The issue is that Pakistan may have decades of experience producing missiles,
but it lacks both the experience and capacity to produce those missiles at scale.
This is an economic problem in general and an industrial constraint in particular. We don't have policies, let alone mechanisms and funding, geared towards industrial defence programming.
Hence why we're at a point where some folks (including our resident ex-PAF IR scholar) are stuck on PAC apparently being better at making JF-17s than HAL is with Tejas, but completely, entirely, and shamelessly ignoring how HAL can source alloys, composites, DEECs inputs, gas turbine inputs, flight control systems, etc, etc, all indigenously while PAC must import all of that from China or other sources.
In general, our side can't even converse or think clearly on this matter, much less come to an understanding of what's necessary, hence why people like
@JamD have to repeat this over and over and over again until it lands.
And the bigger tragedy is that
we did have industrial experts, i.e., the many folks and entities that contributed towards our nuclear program. Thus, if nat-sec leadership held itself accountable, we probably could rekindle the spirit and start building that industrial capacity.
