fact 1: congress is hostile to pakistan and thus will not allow FMF any more
facts 2: you mentioned USA want a parity in indo--pak scenrio which is wrong(this started the discussion)
fact 3: CSF fund is dead, if resumed will need approval from congress which again is going to be difficult
fact 4: india is investing heavily in lobbying in USA which pakistan ignores
fact 5: afghan leverage that pakistan has is strong but USA has a stronger IMF leverage
Fact 6: most pakistanis live in delusions of early 2000s and 1970s that USA favours pakistan, nothing can be far from the turth
best case scenario USA allows full pay f16s(too expensive not worth it anymore, the reason why PAF walked from B52) or used f16s via EDA(less likley, as even israel sales were blocked)
