RefUte his analysis, not attack his person.
Out of his observations which I have summarised in 9 points, I am only unsure about point number 1(how would he know the numbers anyway?).
All the rest sounds credible.
1)Are the PLA encamped in the Galwan valley?
Ans: yes- many threads on this, complete with maps.
2)Has the Indian army built a '1km road' east into the galwan valley?
Ans: another author also mentioned the same thing- n he's a retired colonel
3)does the Chinese armed forces include a dedicated branch called the PLASSF?
Ans: yes, I have included the wiki link
4)is the LAC a fixed border?
Ans: No, this is why its called a 'Line of Atual Control'- n until today, there is no demarcated border betweem china n India, except at the border around most of Sikkim
5)did India requested the talks or not?
Ans: why would china request 1 if they gained land? Also other authors have mentioned the same thing- that India requested the talks and the china only agreed at the last min.
6)did the Doklam crisis reveal India's posturing on the LAC?
Ans: credible. It brings back memories about Nehru's failed Forward policy
https://m.thewire.in/article/security/china-india-1962-war-henderson-brooks-bhagat-report to the Chinese n that would have made them increase the PLA's mobilization readiness at the LAC
7)is the Indian army a personnel-heavy or high-tech equipped army?
Ans: going by how the Indian armed forces devotes the lion's share of its defense budget to paying its personnel's salary, allowances n pensions, I am inclined to believe this. People dont associate 'high tech' with india.
