In fact one of the underlying reasons for this change is the advancement in two strategic area's which pose a future threat to the U.S.
One is the military's use of Artificial Intelligence, and second is the advancement in robotics and non-linear symbiotic development, which includes tuning into humans emotional composure.
This degree of advancement combined with those in nano technology are projected to reach levels to pose a clear and present danger to the human population without stringent monitoring and controls put into place.
Unfortunately this realignment of responsibilities is already behind the curve in what could prove to be a literal technological revolt!
