We are talking about the standoff as a whole here. If you want to keep going back to one battle, then fine, enjoy your win.Really, you want to cope and go back to the 1962 war comparison again??
Please, withdrawal doesn't matter. PLA has voluntarily withdrew itself much further on many occasions despite winning the battle way harder, general consensus still consider it to be the victor. How hard is it for you to grasp this holy moly...?
You admit that June 15 is a win for China, that should be the end of the matter. LAC has changed (or to be more precise, the false perception from India has been busted, China's perception has always been correct and never changes), that's literally it. Noone is challenging you about disengagement that happened.
however, the facts at the end speak for themselves. The lac is exactly where it was before 2020, and China failed to permanently capture any territory previously controlled by India.
