Strategic Importance of Siachen in Tri-Nuke States clashes!

Before coming to the current era, I would like to take you all back to the history of Siachin.

Siachin is the point where LOC and LAC meets and last point point where LOC ends is known as NJ9248. After setting up LOC, India had given  Siachin to Paskistan in 60s. But in 1984, India captured the some of the strategic points of Siachin and created a filth again while following the footsteps of their forefathers. After creating a disputed place in the region, forces of Pakistan and India came for confrontation which is being lasted till today. Siachin became the highest battlefield in the world. The Siachen Glacier is a glacier located in the eastern Karakoram range in the Himalayas at about 35.421226°N 77.109540°E, just northeast of the point NJ9842 where the Line of Control between India and Pakistan ends. At 76 km (47 mi) long, it is the longest glacier in the Karakoram and second-longest in the world's non-polar areas. It falls from an altitude of 5,753 m (18,875 ft) above sea level at its head at Indira Col on the China border down to 3,620 m (11,875 ft) at its terminus. The entire Siachen Glacier, with all major passes, has been under the administration of India (currently as part of the union territory of Ladakh) since 1984.Pakistan controls the region west of Saltoro Ridge, itself lying west of Siachen glacier, with Pakistani posts located 3,000 ft below more than 100 Indian posts on the ridge. (Ref: Wikipedia).

Now Let's come to the point where I actually wanted take you people.

Siachen is going to play a very important strategic pathway for China and Pakistan. As  I mentioned above the story of India coming over to siachen, here I want to mention one most important thing which is that at the time of 80's, the deep state of India thought that Pakistan and China would capture our states by using Siachin and that was the reason that why India came to the point. Now coming back to the topic again, Since China has captured the Galwan valley and advancing their army to more forward areas. In all this situation, China has cut the route of indian army to Siachen and here the main question raises that why Siachin... If you look at the map of Laddakh and Karakoram Highway, you can find the answers of your questions quite easily. Siachin would play the path way to counter India in every aspect if Pakistan shakes hands with China over NJ9248. China is already advancing towards Arunachal Pradesh and here Pakistan can get back siachen very easily. The silence of Pakistan in Sino-Indo conflict is hitting India very hard and they are pretty sure that Pakistan is going to do something at somewhere at sometime.

India has built Dolatbeg road along LAC to cut the karakoram hghway and to ditch China through breaking CPEC and that is the same route which leads to NJ9248. Now China has come up till Galwan Valley and blocked all the supply chain route of Indian Army to Siachen. This whole game rotates around a point which is "There will be some adventure at NJ9248" which can be sooner or later. Few weeks ago, India also spread that Pakistan has moved its army to Gilgit Baltistan and some airborne of PLA also spotted at Sakdu Airbase which was nullified later by DG ISPR. This is how India is cluttered about Siachen and it knows that India might have to lose chicken neck or NJ9248.
