Would this "super power" would try to take back territory that it humiliatingly lost to China in 62 war or would continue to dream about Gilgit Baltistan only?
Super powers are not brainless but shrewd one. They know exactly what to take back and what to be left gone.
The territorial dispute with China is somewhat vague.. for us we lost the territory since we claim all, for chinese we are holding their territory. Since border were never demarcated, its all perception who lose what.
But that is some issue between two future super powers, you wont understand unless you comes under Indian folds (imminent), so leave it to us to resolve.
