What I don't understand about discussions in this thread is that RF is treated as almost magic and 'new technology' can make it do anything. Electromagnetism is virtually perfectly understood and there is nothing more it can do, definitely not responsible for nausea ffs without burning you from the outside... (unless it's ionizing radiation at the other side o the spectrum from RF but radiation sickness is also well understood and would be super hard to miss). Not to mention sound that apparently is being heard...

If someone really is targeting US diplomats worldwide, with those sets of symptoms, why does it have to be a sci-fi tech instead of, old as time itself, plain poisoning
