Yes I do understand, but you fail to take into account that a costly campaign in Tibet may be worth the gains to be made. China's going to fall because Indian troops remain on the ridges? The Chinese have far better infrastructure there and the ability sustain a prolonged presence. You're also bringing in the past, of course the Chinese withdrew due to the logistical limitations but they have moved on from that now.
For your reference again;
China’s improved infrastructure in the TAR and near the LAC has added immensely to its military capacity. China’s ability to rapidly deploy forces has increased “tremendously with the infrastructure built up over the last decade.” All-weather roads and rail infrastructure in addition to a number of airstrips that have come near the LAC give it an “edge in deploying forces.” With the improved infrastructure, China can now deploy up to 32 divisions (previously only 22), and, importantly do so year-round. Additionally, China’s creation of logistic and fuel depots near border regions suggest that China is attempting to improve its ability to not just rapidly deploy forces but also to sustain them for a significant period of time. [8] Clearly, China’s infrastructure development gives it a huge advantage over India at the LAC.
India’s capacity for an effective counter-deployment has been undermined by its torpid approach to improving its overland travel infrastructure near the LAC. Chinese border roads run almost up to the LAC or even cross the LAC into the Indian side; a road in the Siri Jap area in Ladakh runs 5 km into Indian territory, for instance (Times of India, May 26, 2013). Indian border roads, in contrast, stop well ahead of the LAC, sometimes even 50–70 km from the disputed border (Asian Age, July 21). [9]
Daulat Beg Oldie, India’s most significant outpost adjoining Aksai Chin, is yet to be linked by road. Tawang, an important bone of contention in the Sino-Indian border dispute,
has just a single, narrow, pot-holed road linking the town to Bum La, the last border post on the Indian side of the McMahon Line. Conditions on the Tawang-Bum La Road are so poor that it takes three hours to cover the 30 km distance. Even trucks and other heavy vehicles cannot ply this road. While the condition of this road hasn’t improved since 1962
, the Chinese have constructed a four-lane highway running within 4 km of the McMahon Line. It takes the Chinese a mere 45 minutes to reach the Bum La Post from Sonajung town, which lies 37 km from the McMahon Line on the Chinese side (Arunachal Times, June 6, 2012 and Outlook, October 22, 2012).
The absence of roads to the LAC means that supplies for outposts in forward positions have to be airlifted. This is the case with Daulat Beg Oldie, for instance, where supplies must be airlifted, leaving personnel and operations here extremely vulnerable to poor weather conditions and enemy action (
India Strategic, September 2013).
The absence of roads and rails would be felt especially in a time of crisis. India’s mobilization of forces to forward posts would be severely hampered as it will have to depend on aircraft to augment force levels. Importantly, the full potential of augmenting troop levels, raising strike corps and improving air strike and defense capabilities are likely to be tapped only if these are supported by robust road and rail links. In the latter’s absence, “the cruel Himalayan terrain reduces even the largest divisions to isolated groups of soldiers sitting on widely separated hilltops” (
Business Standard, April 25, 2013). With a strong road and rail network, India could reduce force levels in the forward areas and station them instead at lower altitudes, with better weather conditions. It could rush troops to the borders when needed; trucks and trains would enable it to move large numbers of soldiers at short notice. This makes it imperative for India to focus its attention on improving overland links to the LAC.
The plans for strategic roads and railways could make a positive difference. Construction of the Tawang-Vijaynagar highway and the Guwahati-Tawang Road via Tashigang in Bhutan could reduce India’s current vulnerabilities along the McMahon Line. The latter, for instance, would not only reduce dependence on the current Tawang-Bum La route but also allow for bypassing the Se La pass that is prone to avalanches and landslides. It would also cut travel time between Guwahati and Tawang by six hours (
Indian Express, October 16, 2014 and
Arunachal Times, April 30). Besides, the Indian government plans to construct three strategic railway lines—the Missamari-Tawang railway line, Murkongselek-Pasighat-Tezu-Parasuramkund-Rupai line and the North Lakhimpur-Along-Silapathar line—in the Northeast. Of these, the Missamari-Tawang railway line would strengthen logistic support to the strategic Bum La post. Missamari is home to an infantry division, air force station, oil depots etc. Troops stationed at the base here could be transported in large numbers via train to Tawang within hours (
Economic Times, May 10, 2015).
India is however addressing some of the shortcomings, but it's a case of playing catchup not taking the initiative, which lies with the Chinese and continues to grow.
The Chinese will beat you alone, please don't talk about a two front war.
