Was the government's explanation for Havana Syndrome accurate?

After much concern and controversy about the sickness originating in Havana that affected many United States diplomats and spies, many turned to the government for answers.

In 2023, the U.S. intelligence assessment pointed to there being no involvement of a foreign adversary, but now, at the beginning of 2024, we are led to believe something different.

According to nationalreview.com, "A yearlong investigation conducted by the Insider along with journalists from the German publication Der Spiegel and CBS’s 60 Minutes culminated in a series of explosive reports on Sunday night".

According to the most recent Havana Syndrome segment on CBS' 60 Minutes, new evidence has emerged that could potentially identify the perpetrator, finally offering answers after years of unresolved questions.
