The other shift is the shift from corrupt arms contractors to utterly corrupt logistics contractors. Love or hate Northrop or General Dynamics or Lockheed Martin or Raytheon, but at least they make hardware. One of the largest defense contrators is now Cheney's old company Haliburton and its KBR subsidiary. They don't make weapons. For a price they provide housing, etc. Trouble with rockets and airplanes is that even the F35 and Osprey had to fly sort of, and that's hard. With logistics the grift is a lot easier.
So many of our weapons depend on satellites.
When WWIII comes, the first things to go will be the satellites, then what?
