USAF has Ops all around the world where as PAF's Ops are very limited and incomparable with USAF. Very weak argument.USAF have F-16 then Why F-18?
They Have F-14 then Why F-15?
Russia Have SU 35 then why Mig 35.
Dear, every aircraft has its own worth, JFT is our backbone but for research and development to teach your Aeronautical students it is best policy to rebuild F-16.
Best example is China J11 J16 F7pg all are copy.
We can change little in canopy or wings this little change will allow us to rebuild according our needs.
