Like I mentioned, I can think of a half dozen innovations. Some of them would neutralize the entire American military machine.
Remember, our technology is just one aspect. The weakest link is still the human element: whether it's the operator, the command hierarchy, or the adversary's society. Americans were actually working on a 'gay bomb'. Both the Russians and the Americans spent money on ESP and psychic phenomena, and it's safe to suspect that, out of the $700 billion budget, a few millions are still being spent that way.
Some of the innovations I am thinking of don't even involve ESP, but straight mainstream science.
Our technology may let us touch the stars and planets but, in more ways than we like to admit, we are not much different from that jungle ape sucking on straws.
