US once offered 110 A-7 H Corsairs to Pakistan air force,
A-7 were offered by Dr. Kissenger as a "carrot" to Pakistan for its nuclear program. Pakistan never entertained this offer because these aircrafts had no tactical value to PAF. Read all the official and unofficial records or reports of PAF, and you will never find them showing any interest in these aircrafts.
PAF was offered 50 F-5E by Carter Administration in 1978, but again, PAF never entertained this offer. Prior to this offer, the US offered more F-104, which again were never entertained by PAF because then they had withdrawn their depleted fleet of F-104A from service.
After the invasion of Afghanistan by the Russian, Carter Admin. offered Pakistan $400 million aid for five years, which included forwarding on impounded Iranian F-4, which was later withdrawn because of trade for hostage with Iran.
Again, after the Russian invasion of Afghanistan, some congressmen made a suggestion that PAF offered those 110 A-7, but the administration never gave a second thought.
Prior to agreeing to offer F-16 A/B to PAF, a combo of F-5G and F-16 J79 were offered to PAF, which they rejected. Portugal, Thailand, and Greece received used A-7 in the mid-80s, not in the 70s.
