Ugh, this has been rehashed so many times.
Firstly, even the Migs we had were far-far technologically inferior to anything pak had.
They had abysmal range, fcs and above all had NO counter to PAF's American supplied Sidewinders(which were were the benchmark for air combat weapons at that time).
The situation is much-much different now.
We have maintained a technological gap since the 90s, proof being PAF refusal to even engage us in Kargil.
I mean why didn't PAF defeat us in 99, after all IAF is no match for PAF even with our superior numbers?
But, do continue to beat the dead horse just let me remind you, the 60s and 70s are long gone and aren't coming back.
