I think the order to release video to humiliate China came from the top.. May be India decided China had crossed a line.. and costs had to be imposed on Xi Jinping.. and the carefully constructed tough guy image of PLA.. Because, PLA emphasizes "winning without fighting from Sun tsu".. If that has to work, then the enemy has to think that all PLA soldiers are like the hero from Wolf warrior movie.. You crush that image , and you diminish China's military effectiveness.. because, even a superpower will weaken and collapse, if it has to go to war, every time it has to coerce an enemy.. The reign of a major power depends as much on the enemies willingness to be bullied, as it does on the major powers capabilities, as winning without war, conserves the great power's resources.
