My Dear Young Brother,Sir
Sir you can answer it much better them me, as mashallah you enough experience and links to better judge it
In my point of view USA will not in favour of giving that semi sealth coating to pakistan specially, can give to other may be. Usa still in race of intail jet deal candidate with rename of f21 which also have aame coating.
Secondly india is still candidate for other equipment, as i read some forum india came third number of defense procurement.
For evidance when india select rafale instead of usa option to accommodate thay for for apache and chinook instead of much cheaper option of Mi 28 and Mi 26 for which russia was bagging them
I dont believe in spoon feeding, neither my kids, nor you! You are looking at the negative of why the US "shouldn't sell to Pak". Now think about the positive side.
