“When you have eliminated all which is impossible, then whatever remains, however improbable, must be the truth.” – Arthur Conan Doyle, The Case-Book of Sherlock Holmes After years of cross-continental investigation and millions of American taxpayer dollars spent, the Central Intelligence Agency has concluded in an internal probe that the so-called Havana Syndrome is not the result of a deliberate global campaign by any hostile foreign power. In other words, not Cuba, Russia, or China, all of which had, at one point or another, fallen under suspicion. The syndrome describes a set of medical symptoms with unknown causes that have mostly affected United States government personnel within the diplomatic, intelligence and military communities working out of US diplomatic compounds. There have been hundreds of such cases. This week, reporting the results of an internal investigation, Politico quoted a top CIA official: “We don’t see a global campaign by a foreign actor.” The Wall Street Journal reported last week that during the summer of 2021, in Geneva, three American personnel reported symptoms similar to the Havana Syndrome. At least one individual was evacuated to the US for treatment. At the same time, the US embassy in Paris also reported one suspected case and instructed staff to report unusual symptoms. US personnel were first diagnosed with the syndrome in Cuba in 2016 and then in China in 2018. Since then, such cases have surfaced in Russia, Tajikistan, Austria and in a number of African countries. It sounds like a repeat of the Gulf War Syndrome. If the cause or causes are not foreign, then it must be something domestic or internal. Instead of calling it the Havana Syndrome, it should be renamed the US Embassy Syndrome. CIA says ‘Havana Syndrome’ not a foreign power campaign One commonality is that most sufferers have worked out of US diplomatic compounds. Though they are often described as “diplomats” in the news, everyone knows many US officials work abroad with intelligence and the military while using diplomatic cover. Assuming it’s not an outbreak of mass hysteria, something which cannot be ruled out, given the state of US society, it must be something common within those diplomatic compounds. Sonic weapons and microwave beams were at one time suspected, though now dismissed. But what about the unanticipated medical effects of the US government’s own advanced electronics and surveillance equipment or exotic weaponry? Whatever it is, Americans should look within, something they should do far more often.
