No, there was no issue because Pangong is an area of differing perceptions, and confrontations between patrols are normal. The main cause f last year's dispute was PLA setting up permanent structures.So you are saying PLA always playing around F4 and Indians had no issue with it in 2017 or 2018 or 2019 but around May 2020, that was when the conflict started? Okay.
So you are saying just because there is a rock blocking a 1D path for a vehicle, a 3D person cannot traverse past that obstacle resting on a 2D plane? Okay.
Yes finally we agree that both do patrols. Possibly in their own ways and according to their operational whatevers. What's important beyond this point is how much patrolling did India do and how much China do? Well China says India patrolled too much and China had to respond. Four Star Indian General confirms that they patrolled much more but an Indian colonel says they didn't. Hmmmmm what to pay attention to and what to ignore. You made your position clear and I have mine with this one.
I never said India wasn't patrolling disputed areas, just that in the specific case of Panong, PLA was blocking India from going past finger 4, as shown in the video. So far, you have not provided hard evidence otherwise. That wasn't the only example either, I am pretty sure you have heard of the Depsang bottleneck where similar confrontation has occurred.
There is no reason why what happened in the video on that specific incident couldn't have happened on other occasions.
