political commissar are usually more powerful than CO, they report directly to the party bypassing military hierarchy.
which means a political commissar can countermand a PLA CO’s order if they are not in sync.
That's correct. Even in the 1967 Nathu la clash, it all began when the political commissar was roughed up twice in a few days by our soldiers and ended up losing his specs. The commissar enjoys a high position and stature and this was construed by them as loss of face. The second time him he got his ass handed over to him, the clash began in all its earnest.
The 1967 incident has quite a few parallels to the Galwan valley incident. Even there the CO, Lt.Col Rai Singh was martyred along with his soldiers in the open without any warning. Most of our casualties were be because the perfidious chinese opened fire without provocation. Seeing the CO and the Soldiers going down, the remaining soldiers got their act together and even charged at the machine gun nests. Later, the arty chipped in which absolutely decimated the chinese. Despite rhetorics, we held our ground and the chinese backed off.
Few months later, the Chinese again tried a similar stunt in Cho la and again the Gurkhas got the better of them with their Khukris tasting blood.
The chinese may start it but we finish it at our terms. By all indications, the same happened this time too.
Point is the Chinese only understand strength and getting themselves getting beaten up twice in quick succession with an adversary who they considered inferior wisened them up.
Also these cowards used to get absolutely humiliated in physical altercations with our troops, notably the Jats and the Sikhs and hence resorted to throwing stones. The situation is not very different even now where we still kick their asses when they try to act too smart whenever they attempt to force their way in.
