I think you're mistaking silence from the "folks in charge" with complicity with the populist journalism that runs rampant in India. I've spent more time on 1962 sino-Indian war than I'd care to admit but one picture that consistently emerges is how traumatic that event was for the Indian psyche and how it will always taint the common Indians feeling about China. No amount of rational thought or evidence is going to make a difference here. They were hurt and their government told them, the reason why they were hurt is China and not their inept policies and lies.
The Indian government was trying to pass the blame temporarily but now I think they've realized it's created a bigger problem down the line, they can ill-afford this hostility against China but neither can they come clean. They have a tiger by the ears.
So here we sit. The average Indian is confused and angry, wants a reckoning , because they believe China has humiliated them out of cruelty. The government is afraid to tell them what really happened, lest that blame be shifted to them, so the Indian education system won't teach the 1962 war, the government doesn't make any public statements about the official history and the Brooks Henderson report stays classified even after 50 years.
