Ajai Shukla is literally the only person mentioning pps 18-20. No credible Indian media or even any statements by the Indian gov. mentioned them.That think thank shills map doesn't explain "everything". If it did, I wouldn't be bringing up Ajai Shukla's map. His analysis is partisan at best but lacks the depth.
Two things ( I keep reiterating but again)
1. Where did the Patrol points go? Did these patrol points even exist? Since Ajai Shukla has demarcated it quite precisely, there is big importance to that map over Mitra's.
2. If the Mitra map is right, India should not have any issues with China regarding PP17 A.
And Shukla is the clear definition of a partisan. Iyer has his biases, but he does not let them interfere with his analyses. His map was clearly showing the ground positions of both India and China at the time. And almost a year later, Detresfa's image is almsst a complete match. i have already provided reasons why as per the Indian pov, there are still problems in Gogra Hot Springs(though more specifically hot Springs.)
Anyway, "think tank shills" are far better sources than political operatives like Shukla.
