The speculation that Cuban and Chinese state agents could have used some kind of sonic weapon to attack US diplomats is more in the realm of science-fiction fantasy. Both countries deny any such activity. There is no such weapon known to exist. Also, the US doctors who examined the diplomats evacuated from Cuba could not find any casual explanation. The absence of an external source for the injuries appears to be the official US position too, according to the State Department last week.
Significantly, the US doctors studying the Cuban cases said that all the individuals may have undergone a common experience related to their brain injuries.
Rather than speculating about a foreign agency being responsible for the injuries among American diplomats, or rather spies, perhaps the focus should be put on their own side. Were these individuals subjected to some form of hi-tech training run by the Pentagon or the CIA?
It is known that the Pentagon’s Defense Advanced Research Project Agency (DARPA) is investigating brain stimulation devices to greatly enhance learning ability in subjects.
Nevertheless, despite the unknowns, from what we do know already, it seems a plausible posit that the recent upsurge in brain injuries among US diplomatic staff may have been caused not by “sonic attacks” in their host countries, but by their own superiors at the Pentagon or CIA conducting some form of clandestine program to create “super spies”.
