I've said it many times, Pakistan needs to create its own SAM network, two tiers at the LEAST. Then a short distance point defense tier. TOT can be obtained from the Chinese I am sure. But this should be probably one of the highest priorities. If you network your borders with multiple SAM system internally produced in numbers, you've given yourself an offensive punch immediately. Your so called enemy is right at your borders (although the real enemy the Talibastards are right inside your society), but for any wars with India, you could theoretically hit IAF's planes 50-60 miles inside its territory. But you guys need long range and high altitude SAMS ASAP.
I don't know if the comparison with Israel helps here as if it was to happen now, Israel would probably fly deep inside anyone's territory and probably have minimal losses.
