The proposed mechanism of microwave or sonic waves is completely implausible, to the point of absurdity. The only way either could incur brain damage would be through either heat or mechanical stress, both of which would be readily apparent.
If this is a genuine issue then the mechanism is almost assuredly completely different, and personally I don't think it is some scary communist death ray that they would, for some reason, use on US and Canadian diplomats.
Unless the diplomats are all actually covert staff, in which case there would be a motive, but then some kind of chemical is much likelier.
This is IMO so implausible as to put the entire story into question. There is no way this is a microwave or sonic weapon. A microwave or sonic weapon could not cause occipital nerve damage so specific and without leaving any obvious traces of mechanical trauma and/or heat damage. It would also very probably be quite notioeable.
