Repeating a lie a million times doesn't make it a truth my friend, especially when a billion+ people are here on this side to uphold the truth.
A detailed analysis of the stark differences in the military build up on two sides of the border clearly shows that China was preparing for an attack and India was not, this was stated by the military generals of that time and it turned out to be true.
And Nehru was not a Chinese with knowledge of Chinese language, that he would say "Hindi Chini Bhai Bhai" in Chinese, that doesn't make it a lie. Your leaders also speak in Chinese and we interpret it in a language that we understand, that doesn't make your leaders liars, does it? Silly argument.
Military professionals can analyse the build-up and its pace to understand whether it is for an imminent attack or a regular affair, 1962 military build-up was identified as a build-up for attack by our generals, as far as I know, the present position of Chinese military with our border is not being identified as something for imminent attack by our military professionals.
But the point is OUR NON-EXISTENT MILITARY BUILD-UP in 1962, that clearly showed that we were not preparing for a war, neither we had any intention to attack China, China attacked us and dragged us unwillingly in a war that could be completely avoided.
