The US Military Industrial Complex is still alive and well and ,for it, the process of war seems to be everything & not the outcome.
Nowadays, however, as US industry/manufacturing weans one has to wonder how significant the US "Industrial" component will be or will the Military have to rely on an increasing amount of imported war materials & equipment. For example over the past decade, Aus has been supplying the US Navy with smaller patrol boats.
The question is, given the US is being gradually pushed back "on the ground" globally, can it re-invent itself with alternative command/control strategies to still retain global dominance. Despite "Star Wars" being spruiked in the Reagan era as being the ultimate War platform, that does not seem to have come to fruition yet. Perhaps the closest the US has got to "remote " warfare is terrestrial surveilance from space & the CIA's drone technology.
It will be interesting to see if the 20 year Middle East wars have killed the US appetite for war for at least a generation as did the Vietnam War or will we , like Monty Python, see "something completely different"
