First of all the Armys' account indirectly reveals that China was actively involved in land grabbing till 1986, have we managed to reclaim lost territory, why silence on that.
Even now China is our natural rival because India is a successful Democracy hence it is a disturbing role model in eyes of dictatorial Chinese leadership, how can they justify themselves to restive Chinese public.
Secondly the area of Himalayas under illegal Chinese occupation is source of water for mighty rivers. As water shortages emerge this area is both a prime real state & occupation will give handle to blackmail India.
Thirdly according to scenerio report of American Think tank to pentagon(nearly a decade old) there is a high probability of another Indo-China war which can easily escalate to tactical-nuclear exchange if not more.
When it comes to national security we need to be prepared for worst & hope for better. We dont need to repeat another battle of 1962-Panipat-or Plassey. Three bitter experiences are enough now no more
