My point had to do with Pakistan. What point is there in purchasing these planes?
Uhh, for the same reason we buy fighter planes for the USAF, USN, USMC?
Regardless of if you think the Paki's are on the *right* side or not on any number of military conflicts they have been in in the past or may get involved in the future, fact is the Paki's have been in miltiple hot shooting wars with India including, gulp, significant air to air combat sorties.
I'd imagine the Paki's consider another fight with India a rather distinct possibility in the future, ... and they do live in a geopolitical neighborhood stretching from the Middleast to Central Asia to Southeast Asia where there are a lot of hot fingers on triggers (including their own).
