There is a thought that seems to have alluded us..., and that was the absence of the Viper in this entire episode.
We all know that as per the US's End-User Agreement, we cannot use the F-16's against India in an offensive role. That Agreement does not cover defensive role.
So, since the IAF did not cross the LoC, it explains why there is no mention of Vipers.
The Viper has been the frontline Fighter for decades and not going into its History and capability..., the serious question on the US's mind must be: Does Pakistan really need the US anymore in terms of Military Aid ?
The J-10C & PL-15 (still less in numbers) out performed The Mighty Rafale.
Pakistan hasn't bought any Military Hardware from the US since ... Musharaf era.
A week back..., the US would have thought that Pakistan would always want to buys more Vipers - even used ones.
Looks like those days may be a thing of the past.
