Pakistan's GDP is $400 billion (probably less, due to government posting false statistics), it's last year budget was $62 billion, and official defense budget of $10 billion, with it unofficially being between $15-$20 billion (90% goes to just paying salaries and maintaining current equipment).
What money does Pakistan have to fund such a project?
Project Azm failed due to both lack of resources, and not enough knowledge and industry. PFX is more reasonable in its goals, but even that's looking like it won't achieve what it promised.
