Not sure what you mean by that. Are you saying there is something incorrect about detresfa's images(I am assuming he is who you mean by "pro Indian sources."
Sure, satellite imagery is not perfect, but they are the only clear and unbiased evidence we have to work with.
Not at all.
I'm saying his and all other internet OSINTs' materials do NOT show any evidence of India "winning" anywhere in anything. Troop movements in this disputed land has always been politically controlled not due to military fighting. There was no fighting save for some wrestling pushing fests and that night in June which turned lethal and possibly not by accident (we'll ignore this topic since it's been talked about for hundreds of pages).
Satellite footage only really proves one thing for certain - both sides were in and are in standoff within the disputed land stretch with China mostly at where they actually control i.e. not the aggressor at the present moment. Pangong was easily the focal point of the standoff has been disengaged.
China has been expanding some facilities which have long been there and behind the blue line.
Movements have happened back and forth according to political will and negotiations e.g. Pangong standoff and PLA going from F8 to F4 and then back to F8. If Indians want to make this particular aspect into some win, they should be asking themselves why PLA would go back to F8 if they held F4 and wanted to capture to F4. It wasn't because India was too scary otherwise they wouldn't have stayed there for a year and left unchallenged. They left and India agreed to not step beyond F3. If they want to believe that India never patrolled beyond F3 anyway, well they should feel good then. India won. Ignore that none of it adds up but whatever.
What else do satellites show? That Indian build up towards dispute was certainly happening and fairly significant compared to having nothing. Okay this balances what China's got on east of blue line so it's udnerstandable to me but the CCP considers that threatening and decided PLA occupying to F4 is the correct response/message - that China cares about the remaining 20% and won't let India begin setting up salami slicing de factor occupation starting with build up behind and patrols within.
They also show that right now, India has nothing to be complaining about and China is barely within disputed stretch at Gogra HS while India is far further in front of the LAC. This is my understanding! What interests me is why India refuses to disengage while the onus is now on them to. It must have a lot to do with understanding that disengaging which PLA would mirror with move behind blue line, would be a step towards establishing entire thing as buffer and a step towards losing Indian claims not only of the 20% but the 80% behind that.
