After investigating 1,500 cases in nearly one hundred countries, US intelligence reports that there’s no sign that adversaries are behind Havana syndrome. “Many of those cases, officials said, have been linked to other potential explanations aside from a foreign campaign: medical illnesses, malfunctioning air conditioning and ventilation systems, or electromagnetic waves coming from benign devices like a computer mouse.” When you hear people describe their debilitating and long-lasting symptoms, it’s pretty hard to believe they were the result of a rogue computer mouse. I recently recommended the Vice podcast, Havana Syndrome. It gives a good overview of what we know so far and will leave you wondering about today’s finding.
