I wonder how many people have listened to this Bharatshakti podcast with Brigadier Chatterjee in conversation with Nitin Gokhale. Listen to it from 17:10 to 22:15. To summarize, the conclusions reached by Nitin Gokhale are based on his conversations with as he calls them "very senior functionaries" in the establishment in India. So in this case he is definitely acting as a GOI mouthpiece and therefore this is an authoritative account of GOI thinking on the Ladakh issue.
He says that there are 4 reasons that GOI believes that China has acted the way it has:
1. To test the deployment and capabilities of it's forces in the Western Theater Command after the reorganization of the Chinese armed forces on Theater lines.
2. To avenge the setback at Doklam which is seen within China as an insult that rankles domestically as well as with the wider international audience.
3. To test the preparedness and resolve of the Indian armed forces to deploy at the border in response to the Chinese build up and to test the resolve of the Indian establishment to face China militarily vs opting for face saving political negotiations as was done by past Governments in India.
4. To try and force India to subjugate itself to the Middle Kingdom that China regards itself as.
He goes on to say that GOI has resolved to:
1. Stay resolute at the border and not to submit to Chinese coercion under any circumstance. That this is a very crucial time in which India cannot be seen as bowing to Chinese pressure and coercion and will not.
2. At the same time, be open to for talks and discussions with China to settle the immediate confrontation.
