So which territory that was controlled by India as of 2019 was lost? You are correct in the sense that India des claim Aksai Chin to be Indian territory, so I suppose you have a point there, but during the whole recent border skirmish, China only moved past the Chinese claim line by at most 1km(a very liberal estimate) even though China claimed the entire Galwan valley, effectively shifting the CCL by 4-5 km. So what territory did India lose? And obviously, India will move back to its pre- April positions once it is confident in Chinese intentions. Already India has secured the DBO road overlooking Karakoram, and finished completion of feeder roads and bridges over the Galwan and Shyok, so there is no benefit for India to stay in a narrow valley with rising water levels. Of course, India is still waiting to verify Chinese intentions, which is why it still maintains a thinned out but sizeable prescence within 1km of the CCL/LAC mutually accepted by both sides. So what exactly has India lost?
BTW, I am happy the situation was resolved peacefully without India losing any land. Interestingly it seems to be Pakistanis parroting ridiculous claims of China occupying 60 km of Ladakh, which contradicts China's own claims.
Tell you what. Show me the extent of Indian land lost to China that you claim and back it up with evidence, and I will stop posting.
