I did a longer analysis that focused more specifically on Cuban actions in the documents and didn't find much difference - still largely harassment and jamming radio stations:

Query

"Cuban intelligence or military programs/activities/incidents in the United States"

Overview

This report summarizes intelligence and military activities involving Cuba and the United States. Key themes include radio interference, harassment of U.S. assets (particularly Guantanamo), and plans for retaliation or defensive response. Much of the intelligence indicates that while there were threats and hostile actions, they were generally limited in scale and did not provoke large-scale conflict.

Key Facts and Activities

  1. Jamming of U.S. Radio Stations – Cuban forces engaged in electronic interference of American broadcasts.
  2. U.S. Defensive Protocols – SOPs were in place to counter such interference.
  3. Retaliatory Military Planning – U.S. maintained operational plans for responses ranging from defense to invasion.
  4. Guantanamo Harassment – Cuba restricted water supply and worker access to the U.S. base.
  5. Sabotage Precautions – U.S. bases were reinforced to prevent Cuban sabotage.
  6. Shipping Interference – Reports of harassment in the Yucatán Channel, Florida Straits, and Windward Passage.
  7. Aerial Aggression – Cuban forces possibly shot down pirate aircraft and pursued raiders.
  8. Attacks on Exile Staging Areas – Cuban forces reportedly targeted areas in the Caribbean used by exiles.
  9. Controlled Maritime Agents – Vessels operated under U.S. intelligence as controlled agents.
  10. Penetration of Installations – Surveillance targeted Cuban diplomatic posts in over 10 countries.
  11. CIA/NSA Coverage – Continued intelligence gathering through Miami (CIA) and Cuban comms (NSA).
  12. Worldwide Communist Penetration – Focus on assessing Party agents with ties to Cuba.
  13. Covert Infiltration & Exfiltration – Ongoing operations extracting agents for training and redeployment.
  14. Signs of Regime Stress – Monitoring of internal Cuban tensions and morale.

Names, Dates, Locations, & Sources

  • Notable Meeting: Sept 13, 1963 – Strategic assessment of Cuban threats
  • Declassified Source: NW 50955, DocId: 32425002, Pg. 14
  • Rules of Engagement: Approved at highest national authority
  • Declassification Status: CONFIDENTIAL; downgraded at 12-year intervals

Key Themes

  • Electronic Warfare: Radio jamming and comms disruption.
  • Guantanamo Tensions: Physical access and resource control used as leverage.
  • Low-Scale Hostility: Acts of harassment without large-scale escalation.
  • U.S. Preparedness: Contingency plans, agent ops, and intelligence mapping.
  • Proxy and Exile Dynamics: Pirate planes and exile staging suggest Cold War complexity.
  • Global Intelligence Theater: Multi-nation surveillance of Cuban networks.

Notable Statistics

  • Controlled Agents: Numerous vessels active in intelligence ops
  • Diplomatic Penetration: 12 active Cuban diplomats under surveillance, 20 more targeted
  • Audio Penetrations: Coverage in 11 countries including Chile, Italy, and Canada
  • Communist Party Ops: 65 global penetrations, 23 directly targeting Cuba

Additional Analysis

The data reflects Cold War-era tension, with an emphasis on monitoring and containment rather than open conflict. U.S. intelligence was heavily engaged, but Cuban aggression was seen as limited and manageable. The threat assessments suggest restraint from Cuba, with calculated moves unlikely to provoke a major U.S. response.

There is also philosophical attention paid to the ethics and permissibility of clandestine operations in open societies, especially regarding covert influence and manipulation.

Final Interpretation

Based on the evidence, Cuba's primary aggressive actions appear to have been radio jamming and base-level harassment. While U.S. intelligence was active and alert, Cuba was not perceived as a serious military threat. The pirate plane incidents seem tentatively linked to Cuban actions, but without strong attribution. The overall tone of the intelligence suggests containment and surveillance, not imminent warfare.
