This mindset is not only of NSA, but IA too. They too are damn against road development in border sectors. Its only after Doklam that they have agreed to it. Otherwise in 2016 they had openly opposed the idea in NE sector.Why hadn't we developed infrastructure in the North East? Because the National Security Advisers over the years warned that this could be used by the Chinese in the event of war!! Lol!
@Tanmay someday you should interact with soldiers in Indo-China border. Their damn attitude you make you laugh heartily. Seen it in Tawang sector.
