What are you talking about? India has camps much closer to the lac than 10km. Except Pangong, the buffer zones are small, at most 2km on either side of the lac. The disputed areas are far bigger than that.
Prior to 2020, India had no camps in Galwan. Now it has four along with bridges and roads.
Both sides have camps within no man's land. You only say Indian camps like Indians won something.
Again tell me what legacy dispute india's won? Zero.
India has camps and infrastructure inside 20% dispute, China does too. You answered his what's changed question with a response that bends the truth by ignoring half of it as if it is a net Indian gain when presence is a net zero and legacy dispute is a net negative since India has lost access to Aksai Chin.
Now it is revealed that Indians suffered humiliating defeat in the tactical side of the topic.
