Geo-Political Maturity
Taking on China along the McMohan Line in late 1962 (“PM Jawarharlal Nehru orders Jawans to throw the Chinese out”, screamed newspaper headlines), India was itself evicted from North East Frontier Agency (NEFA) in the East and Aksai Chin as well as adjoining areas in the West. Chinese stopped in the foothills (in fact at a place called Foothills) of the Himalayas, unilaterally declaring a cease-fire. Some Indian troops even crossed the border into (then) East Pakistan (mainly Sylhet) to escape the Chinese. Two Indian Infantry Corps ceased to exist as entities. The US rushed in help to equip 3-4 mountain divisions, willingly complying with the wish-list for arms and equipment, balking only at the Indian request for submarines. These could hardly be used in the Himalayas.
