Saying "LAC has remained the same for decades" over and over doesn't make it true.In Galwan, LAC has remained the same for decades. If anything, it has shifted east since 1962. Both sides disengaged from the historic Indian claim line, meaning China is farther from its claim than before 2020. The LAC has remained the same for decades, and hasn't shifted despite China's attempts, despite what some indian media/political activists are saying.
In Depsang, China is roughly 10 km from its perception/claim.
In Hot Springs, China is several km from its claim line, the confluence of the kugrang and Changlung. Anyone can see that the only PLA camp left is more than a few meters from its claim line/perception, as shown by the yellow line. India has a camp far beyond its historic limits of patrol(pp15) and only about 2 km from its perception.) PPs are typically located 1-3 km from India's perception of the lac.
In Gogra, there is no PLA presence inside India's perception, even though some Indian media claim that without evidence. Satellite imagery clearly shows the conflict point is limited to Hot Springs/Kugrang Valley. Even Lt. Gen. H.S. Panag agrees that there is no incursion there, and that there is no difference of perception at gogra.
Overall result, with the exception of hot springs, where the standoff is ongoing, and India has a camp well beyond its historic patrolling limits deep within China's claims in response to China's violation, the LAC is the same place where it has been for decades, as shown by the below CIA map. This is despite China's attempts to shift it towards its historic claim lines.
And for those who don't understand, there is the LAC that exists on the ground(de facto) and the Indian perception. India's perception is only different from the de facto lac at Pangong, Demchok, and Depsang. Neither the LAC nor India's perceptions have shifted.
There is no LAC without India's perception. No real LAC and perceived as such. LAC = line of Actual Control.
For the rest, I shall indulge -
Depsang-Coming to where India had to step back.
Galwan - LAC of India shifted back by 1 km. Buffer zone created with new LAC. China laid a road to near the bend. China now claims most of Galwan.
Depsang - LAC of India broke down. China has camps quite far into Depsang. No point of LAC here, China is an odd kilometer away from her supposed Claim.
Hot Springs - PP15, as was discussed before, China's camp exists a kilometer into India's LAC. China is meters away from its Claim lines.
Gogra - beyond PP17A. Indian LAC not clear. But judging from Indian news itself, China is 700m into the LAC of India. (The issue here being the location of patrol points).
Result : China moved closer to its claim lines (except in Pangong Tso which is down south).
India still pushes for further disengagement while China was reported to have replies with "India should be happy with what has been achieved".
