I am aware the US (and most Western nations) make such assessments as policy. However this seems to be purely one-sided as the US has no issue selling AESA equipped F-16IN (BLK.70+) or F-18IN, P-8I etc, or the Europeans selling Rafales, EFT, long range BVR, CMs etc etc to India. How is this not affecting the balance of power in the region?
Surely it comes down to the dollars at the end of it. India just has more.
But talking about F-16s specifically- unless it was the BLK.70+, I don't see a F-16 sale to Pakistan upsetting India too much or altering the power balance of the region one iota.
