For all of your types who say Pakistan is sheltering the Taliban, kindly take your own head out of dark tight crevices. Pakistan has lost over 50,000 people at the hands of the Taliban, and State sponsored mercenaries (that means India), since 911. Pakistan's economy has greatly suffered in the long awaited cleanup of the mess that the earlier US administrations left at the end of the Cold War. Pakistan continues to suffer, both militarily and economically, at the hands of the mercenaries who claim to be Taliban. However, Pakistan seems to have made up its mind about its future and trying its best to root out the evil of armed mercenaries in FATA areas and rest of the country.
For all y'all who say Pakistan is sheltering the Taliban, have you ever been to Pakistan? Have you met anyone from Pakistan? Have you seen our tears when our Children are slaughtered in schools? Have you seen our anxieties when there are state sponsored actors found and arrested in our cities? Have you asked our hearts what we really want?
Regarding these aircraft, it is in US interest to sell the birds, to keep the US industry going. These offers come from US administration. These 8 aircraft are not critical to the defence of the airspace, or to COIN operations. However, the Pakistani F16s are well upgraded to defend the airspace of the country, or to undertake interdiction operations against the mercenaries in the FATA area.
If US doesn't sell, it is their loss not ours. Future administrations will continue to engage Pakistan; like it or not, you cannot change geography, and Pakistan will continue to have a role, whether the neighbours squeal with hammroid pain as they usually do, while they climb their S400 launchers in raised position.
