A) NFS is not a written agreement between two countries, will you trust your enemy during a hostile situation and hope that the missile he has hurled towards you is conventional and not nuclear.
well same can be said for Babur, which infact is a nuclear armed cruise missile
Chances of it being take as a nuclear threat in negligible since the attack would on on sea
B) Your Second point contradicts your first one, by that logic China is insane in pursuing DF-21D cause if it attacks a CBG of any of these countries, it is sure to be retaliated with nuclear strikes. Anyway, that is not the reason for the big powers to not pursue ASBMs, Russia have tried and failed with its R-27K / SS-NX-13, worlds first ASBM. At the end this system was shelved by the russians. Both of them released that it was not feasible to sustain ASBMs and focused on countermeasure, which is what India should do.
lets see how far DRDO takes it, too ambitious i agree
C) You are not reading my posts thoroughly, in my post #22 I had marked in bold and high lighted in red [Its (DF-21D) general theme is slowing down the speed of the missile (less than Mach 5) as it gets closer to the target to maybe give the seeker more time to lock on to target and make unpredictable movements to penetrate defense.] So the missile is not going to be hypersonic (>mach 5.5). Best way to counter this missile is with a Electronic jamming like AN/SLQ-32 EWS, which most of the US ships have and hosts of other counter measure which likes of you and I will never know which goes on board the US's Aegis vessels. As simple as a smoke screen can hide the Vessel from a ballistic missile which relies on satellite based real time imagery to get to its target.
Again its like stating that what use a fighter is, enemy EW suits would jam it
Firstly missiles would be exo-atmosphere (re-entry), its detection would primarily be next to impossible untill it has few seconds to impact. No CBG has a radar that can cover altitude of 60-70k Feet and above
IN would not solely rely on Satellite for detection (which again needs to be looked into) maybe onboard active navigation system and IIR imagery (A/C in a war scenario would have aircraft landing and taking off)

Land based interception are a different game than sea based Interception of BM's, again even if somehow A/C has a powerfull radar to track the BM, what would be the response time ? The laser based defense system concentrates high-power laser on the target to take it down, would it have enough time ?
When we talk about MaRV, how many warhead can it successfully intercept ?
D) Im sorry to tell you this but most of DRDO's project are not asked or needed by the armed forces at all. Many of them are just for the purpose of tech demonstration. Less than 10% of the projects DRDO has worked on so far have been accepted by the forces.
Completely agree with you, but they are decent with BM's it does come late, but them make it
Geez, Is it everything that China does that India must also do? India should developed on its own path/terms. Not following China. Else it will be seen as a follower not a leader.
Do thing you know you really need, not because your bigger neighbour has done it. Geez Asians and ego.
its not about being a leader, clearly if you want to take out an CBG, you need to take out the destroyers and ASW ships along with the A/C, hence MaRV makes sense
