I am not advocating that India should withdraw w/o fight. Also, no one in Dehli can do that and survive. What Pravin saying that IA should focus on the 'domain and front' for China (may be Pak). Such as ZDK03 if can guide Pl-15, our JF-17 can turn off the radar and just launch the missile. Does IAF something like that? Or radar/visible data coming from Beidou is directly seen on JF panels? So PAF/PLAAF intra-operability is getting stronger while IAF has mix of SUs, Rafale, Teja etc I suggest you shd listen Sajjad Haydar videos where he talks about achieving synergy between PAF/PA. All of our people can see the same picture. Unlike IA AD units who shot their own Heli (IFF failed and then they don't know if it was friendly or foe).I do not buy the narrative that India is being used by US as a proxy force for China. If anything, India needs US more than the other way around.
You are right to say that India is ill-equipped to fight China. The large populace in India is aware of this inadequacy. But giving up without a fight is not an option for any country. India will have to go down fighting if it comes to that. To be able to put a respectable resistance to China, India needs US more than it needs any one else. India does not have a choice in the matter. There is no easy way out of this monkey trap.
