Thanks Sarkar ji for the explaination !
This was indeed very subtle. I don't understand if revealing this video proof was so easy why didn't IAF release it when the naysayers were doubting IAF actions in the immediate aftermath of balakot. I understand that you don't want to give in to the 'do-kaudi-ke-log' because that sets up the precedence for any such future doubting. But then by not releasing out these hard-proofs you also underplay your hand in the perception battle. Anyways, there has been enough chintan-shibir on this topic so let me not bring it back.
GoI did a lot of subtle messaging with and post-Balakot, both in how they characterized the strike, and in giving Pakistan enough leeway to wiggle out of the situation without inflaming opinions among their public, so as not to push the situation up the escalation laadder. If things escalated even more than they did after (with Abhinandan, etc), it would've led the international community to put pressure on us and close off the possibility of future punitive strikes.
I suspect not releasing the video was paart of that calibrated response, because it allowed Pak to claim no damage done, and cool things down somewhat at their end. As long as we neutralize a large number of piglets, what does it matter if the other side claims nonsense? The message that needed to go was received by the correct recipients in the Brownpant army. Everything else is noise. And doesn't need a response.
