This could happen if India goes for F-35. Not sure what option we would have if that were to happen. If J-20 is a mature platform by then, we can manage.I hope you're right, otherwise we could see India continue to outpace Pakistan in terms of fighter tech.
Speaking of tech, do you think there's any realistic chance of Pakistan going for the Turkish upgrades for its older F-16 fighters? It's supposed to be on par with (or at least near) the block 70/72.
This would also increase the longevity of the F-16s and allow PAF to continue effectively challenging India's Sukhoi-30MKI fleet.
Otherwise the solution to the Rafale induction is continuous evolution of PL-15 and variants for the PAF.
