Another possibility I haven't seen many people speak of is that this might not be a foreign adversary, but a test by our government itself.
Our government has a long history of testing experimental weapons on its own personnel, such as the MK Ultra Project and Operation Top Hat. I wouldn't put it past one of our military or intelligence agencies to do this.
I've said for years that the Havana Syndrome is just the latest of Syndromes related to workplace injuries. (Previous ones were caused by Agent Orangein Vietnam, Gulf Syndrome from the Iraq War of 1991, Burn-Pit lung-damage from Iraq 2003, Afghanistan, etc, etc, etc.)
Something all those spooks were doing in their diplomatic posts is the cause of Havana Syndrome. But the Government will hide any evidence they have, so that there won't be millions or even billions of dollars in Workplace Injury Compensation claims.
"Blinken has long doubted that personnel are suffering from mass hysteria or some psychogenic event, officials have said. Previous investigations, notably by the FBI, had raised the possibility that the symptoms had a psychological origin, not a physical one, outraging many sufferers who felt their pain had been marginalized and their claims not taken seriously by medical personnel. Experts have emphasized that even if the illnesses were psychogenic, that doesn’t mean sufferers are imagining their symptoms."
I think therein lies part of the problem: it has to either be caused by secret weapons, or mass hysteria. The same kind of outdated thinking is what has caused the dualistic thinking that we see in ME/CFS and longcovid.
Opinion: government workers label things mass hysteria when they have to file reports but cant keep those blank. Tangentially, also in the "toxic lady" case where 5 people were hospitalixed (1 for 2 weeks in ICU), since reasonable explanation werent found, it ended up ruled as mass Histeria.
It is also surfacing that a lot of Historical Mass-Histeria episodes were linked to phisical causes such as hallucinogen contaminated bread, instead to the Devil for the ancients or Self-delusions for the Modern people
>Five of those agencies determined it was “very unlikely” that a foreign adversary was responsible for the symptoms, either as the result of purposeful actions — such as a directed energy weapon — or as the byproduct of some other activity …
>One agency, which the officials did not name, determined that it was “unlikely” that a foreign actor was at fault, a slightly less emphatic finding that did not appreciably change the consensus. One agency abstained …
Is it not possible that this is caused by "secret" countermeasures they use in locales where they can expect extra espionage efforts? Maybe it was out of tune, or the layout or interference or whatever caused unpredictable results?
