Here is some info, though it is dated. Believe it or not, at your discretion. Info used to be found on some rather obscure parts of the internet.
US government 20 years ago had a plane that could pull out every phone call ( land line or cell), every fax, every tv and computer screen, every printer image being printed, etc, from a building that was 200 miles away. The technology has only gotten better.
Also, some of that missing Pentagon money has been spent putting everything our army would need in underground locations around the world. One is in Europe, but not where you would think. All we would have to do is get soldiers to the locations, and they would have everything they need. Literally, they could get there in shorts and sandals, and roll out tanks, artillery, arms, weapons, ammo, food, etc.
There's lots we're not being told.
