lol, as usual you have no practical idea how things work, you simply end up googling every thing.
There is no such thing as sensitive once it comes to academia , things come to academia only bcos they want to utilize the broader knowledge base to solve the problem instead of being siloed as it happens in the companies. In companies they do ensure departmental access is limited but that cannot be imposed in academia.
Second thing is that you dont need to know everything , you only need to know which direction research to know what is happening and build on that. If you are some one who is looking for word to word instructions then you are even unfit to compete with US.
lol, as usual you showed your practical ignorance. One reason why US is ahead is bcos most advanced technologies are available for civilian use in fact there are very few companies which are only defence in nature. Unlike India they dont put classified on every thing and prevent it for civilian usage, if the company sees profit they will commercialize it.
You are going against what's considered common knowledge in the US. You are free to believe what you want.
