You claim as if LM went out of blue to US DCA to get clearance for F-16 sales to India. Nope.
Such sale offers require Request For Information first which was sent to LM by Indian Government. All RFI are requests.
I am typing the same thing for third time.
That's literally what I have said India sent the RFI to LM and then LM goes for permission.Remember that request for weapon sale come to US DoD/ DCA from India, not the other way around. So you can do less with bravado and more with a dose of reality.
But Indian govt did not request the American govt for F16 as you have said in the previous comment(which I have quoted here).
Further this is my last comment on this topic.
