Declassified memos from both sides of the Florida Straits show Havana tried to sound the alarm about Oswald-and the U.S. buried it.
đ´ The Havana Backchannel
While Lee Harvey Oswaldâs trip to Mexico City in September 1963 has drawn intense scrutiny, less attention has been paid to the Cuban response to that visit.
The 2025 CIA and State Department releases show that Cuban intelligence flagged Oswald as "unstable and hostile"-and that warning made it into the hands of U.S. officials.
They just didnât act on it.
đ File: "Comportamiento ErrĂĄtico â Oswald" (DGI Internal Memo)
Dated October 9, 1963, this document from Cubaâs DirecciĂłn General de Inteligencia (DGI) described Oswaldâs behavior at the Cuban consulate in Mexico City:
- He was "erratic and aggressive"
- Demanded a visa "with urgency"
- Mentioned "taking matters into [his] own hands" if rejected
The memo was quietly passed via a Brazilian intermediary to a U.S. consular contact in Havana.
đ§ U.S. Response? Redacted and Discarded
A 2025-declassified State Department cable from Havana to Langley includes the notation:
"Received Cuban comm. re: Oswald. Dismissed as diversionary misinfo attempt. No further action."
No follow-up.
đľď¸ A KGB Intercept
The 2025 dump also included Soviet internal communications showing that Cuban embassy staff in Moscow contacted Soviet intelligence about Oswald after the assassination, saying:
"This is the same man we reported. He was not stable. He mentioned actions against Kennedy."
Soviet officials advised them to stay silent, per the cable:
"The Americans will not thank you for the truth now. This is their fiction to manage."
đď¸ CIA Mexico Station Memo: "Oswald and the Red Triangle"
A memo from the CIA station in Mexico City, now unredacted, includes a hand-scrawled postscript:
"Red triangle file [Oswald] tagged by Cuban consul Alvarez. Labeled potential âAmerican agitator.â"
This memo was buried in an unrelated Latin America folder-until now.
đ Warnings Came-But the Narrative Was Already Written
Cuba warned us.
They tried to alert the U.S. government about Oswaldâs instability and his violent ideation.
But the response wasnât to investigate.
It was to bury the warnings and preserve the pre-written "lone nut" narrative.
The 2025 files reveal:
The truth crossed borders. The cover-up stopped it cold.
