Fact check
Is it true: Havana Syndrome?
It's still under investigation.
The 2020 National Academies of Sciences report concluded that "directed, pulsed radio frequency energy" could plausibly explain some cases. Subsequent CIA, DoD, and IC assessments (January 2022, March 2023) narrowed and then broadened scope. The March 2023 IC assessment stated with "varying levels of confidence" that a foreign adversary was unlikely responsible for the majority of cases, while noting some cases remained unexplained. 60 Minutes and The Insider/Der Spiegel investigations in 2024 reported on GRU Unit 29155 possibly involved in at least some incidents. The case is genuinely unsettled: symptoms are real, cases are documented, mechanism remains contested.
