I don't see how outsourcing is similiar to Rome's nationalization. The US military-industrial complex is extensive in it's research in the extreme, in the early 50s they were experimenting with nuclear powerred planes and anti-submarine suicide bomber dolphins one can only guess what they've covertly tried/achieved since then. If Europe, Russia or China conceives of a way to increase military power they can be sure the Americans have already been there done that 10 times over and bought the snow globe.
