‘Brain-fog’, dizziness, ringing in the ears, fatigue: everyday symptoms of attacks by a possibly extraordinary weapon. In 2016, a number of CIA agents began to report these symptoms, alongside a possible cause of an unusual sound. Now over 200 Americans and Canadians have reported symptoms, and Kamala Harris, America’s vice president, this August delayed a flight to Vietnam because of suspected cases in Hanoi. But what causes Havana Syndrome? Is it the result of attacks by microwave weapons, or is it something more banal? Robert Bartholomew is on the podcast today to talk to James about reports of Havana Syndrome, and the veracity of the microwave weapon and Frey effect theories. Robert discusses the results of experimentation over the years, and the support for a theory of Mass Psychogenic Illness. Alongside Robert Baloh, Robert Bartholomew is a co-author of ‘Havana Syndrome: Mass Psychogenic Illness and the Real Story Behind the Embassy Mystery and Hysteria’.
