Operation Northwoods: The Joint Chiefs' False-Flag Plan to Justify a Cuba Invasion

What Operation Northwoods was, in a paragraph.

Operation Northwoods was a memorandum, dated March 13, 1962, from the Joint Chiefs of Staff to the Secretary of Defense, proposing a package of "pretexts which would provide justification for US military intervention in Cuba." The memorandum was signed by JCS Chairman Lyman L. Lemnitzer and represented the unanimous position of the chiefs. The proposals included staged attacks on the US Navy base at Guantanamo, the sinking of a (real or fake) US ship, the fabrication of a downed civilian airliner blamed on Cuban forces, plastic-explosive bombings in Miami and Washington with manufactured casualty reports, and the launching of a fake Cuban aircraft against a Dominican base. Some operations called for actual injury to US service members; others were to be fully fabricated through propaganda. Defense Secretary Robert McNamara forwarded the package to the White House. President John F. Kennedy rejected it. Lemnitzer was not reappointed as JCS Chairman when his term expired later that year. The memorandum was filed and remained classified until 1997, when it was released as part of the JFK Records Act. James Bamford, who first reproduced and contextualized the document in his 2001 book Body of Secrets, is the source most often cited for the case's public presentation.

The documented record.

The document itself

The Northwoods memorandum is a 16-page document with the heading "Justification for US Military Intervention in Cuba" [1]. It is signed by Lemnitzer and addressed to Robert McNamara. The cover memorandum identifies the package as the work of a "JCS-directed working group on Cuba" within the Department of Defense. Verified

The document opens with a clear statement of intent: "World opinion, and the United Nations forum, should be favorably affected by developing the international image of the Cuban government as rash and irresponsible, and as an alarming and unpredictable threat to the peace of the Western Hemisphere... A series of well coordinated incidents will be planned to take place in and around Guantanamo to give genuine appearance of being done by hostile Cuban forces" [1].

The specific proposals

The memorandum lists discrete operations. The most striking, in the order they appear in the document:

• Staged Guantanamo incidents. "Land friendly Cubans in uniform 'over-the-fence' to stage attack on base," "Capture Cuban saboteurs inside the base," "Start riots near the base main gate," "Blow up ammunition inside the base; start fires," "Burn aircraft on air base (sabotage)," "Lob mortar shells from outside of base into base," "Sabotage ship in harbor; large fires — naphthalene," "Sink ship near harbor entrance. Conduct funerals for mock-victims." Verified
• "Remember the Maine" incident. "We could blow up a US ship in Guantanamo Bay and blame Cuba. Casualty lists in US newspapers would cause a helpful wave of national indignation." The memorandum specifically references the 1898 USS Maine sinking as a precedent.
• Hijacking and casualty fabrication. "It is possible to create an incident which will demonstrate convincingly that a Cuban aircraft has attacked and shot down a chartered civil airliner... an aircraft at Eglin AFB would be painted and numbered as an exact duplicate for a civil registered aircraft belonging to a CIA proprietary organization." The duplicate would carry a "selected group of passengers, all boarded under carefully prepared aliases," then be replaced with an unmanned drone whose destruction would be blamed on Cuba.
• Terror campaign in US cities. "We could develop a Communist Cuban terror campaign in the Miami area, in other Florida cities and even in Washington. The terror campaign could be pointed at refugees seeking haven in the United States. We could sink a boatload of Cubans en route to Florida (real or simulated)." Verified
• Use of Soviet aircraft markings. "Hijacking attempts against civil air and surface craft should appear to continue as harassing measures condoned by the government of Cuba... it is possible to create an incident which will make it appear that Communist Cuban MIGs have destroyed a USAF aircraft over international waters." The plan called for painting US aircraft in MiG livery as Cuban substitutes.

The document explicitly contemplates that some of these operations would involve real casualties. The reference to "casualty lists in US newspapers" in the proposal to blow up a US ship makes the intended outcome unambiguous: dead Americans, blamed on Cuba, used as a casus belli.

How it was rejected

The document was forwarded by McNamara to the Kennedy administration. The exact moment of rejection is not as crisply documented as the proposal itself, but the outcome is clear: the plan was not adopted, no Northwoods operations were executed, and Lemnitzer was reassigned. Verified Lemnitzer's term as Chairman of the Joint Chiefs ended on September 30, 1962. He was not reappointed and was instead transferred to command of NATO forces in Europe. Several historians, including James Bamford, have characterized the non-reappointment as a direct consequence of Kennedy's loss of confidence in the JCS leadership after Northwoods [2].

How it came to public knowledge

The Northwoods memorandum was declassified in November 1997 as part of the document review mandated by the President John F. Kennedy Assassination Records Collection Act of 1992. Among the millions of pages reviewed for assassination-related material, the JCS memorandum was identified as eligible for release. Verified [3]

It first reached a broad public audience through the work of journalist and historian James Bamford. Bamford reproduced excerpts of the document and provided historical context in his 2001 book Body of Secrets: Anatomy of the Ultra-Secret National Security Agency. The National Security Archive at George Washington University also published the full document online with editorial annotation [3]. Both releases occurred within months of one another in 2001 and brought Northwoods from a footnote in declassification-records discussions into general historical awareness.

The corporate authorship

One frequently-missed fact: Northwoods was not the work of a single rogue officer. The document is the unanimous formal recommendation of the Joint Chiefs of Staff — the heads of the Army, Navy, Air Force, and Marines, plus the Chairman — transmitted through their formal advisory channel to the Secretary of Defense. Verified This is the documented institutional position of the senior US military leadership in March 1962, not a memo from a fringe planner [1].

The institutional framing.

The Joint Chiefs' own framing of the memorandum, embedded in the document itself, is that the proposals were a menu of options for civilian leadership consideration, not a recommended course of action presented as a fait accompli. The cover language uses the formulation "the following actions could be undertaken" rather than "should be undertaken," and the body of the document repeatedly notes that the political and operational decisions about which (if any) elements to pursue rested with the civilian leadership. In this framing, the chiefs were doing their job — surfacing options for political masters — not freelancing.

Contemporary defenders of Lemnitzer (including some retired officers writing in military journals after the 1997 release) have emphasized this framing. They note that contingency planning, including for unpalatable scenarios, is part of the JCS function, and that the document was promptly rejected by the civilian chain of command exactly as the system is designed to work.

The countervailing view, articulated by Bamford and most subsequent historians, is that the document goes well beyond contingency planning into operational proposals with specific manufactured-casualty mechanics, and that proposing the deliberate killing of US civilians to manufacture a casus belli is not within any defensible reading of military advisory function. The JCS may have surfaced the options. The options themselves were the problem.

The unanswered questions.

The full working-group documentation

The 16-page Northwoods memorandum is a summary of a longer staff-work product produced by the "Caribbean Survey Group" working under the JCS Joint Staff. Drafts, working papers, alternative versions, and the deliberations that produced the final memo are partially extant in the Joint Staff records at NARA but have not been comprehensively released. Whether the working group considered additional options or rejected some during deliberation is incompletely documented.

Kennedy's own response

There is no formal written rejection memorandum from the White House in the released record. The rejection appears to have been delivered orally, possibly directly to Lemnitzer in a meeting in March 1962. Robert McNamara's later oral histories at the LBJ Library mention the package only in passing and do not provide a detailed account of how it was killed. Disputed

Whether elements survived in modified form

Some Northwoods-adjacent activities — particularly the use of false-flag mechanisms in covert action — were subsequently considered or executed by the CIA's Operation Mongoose without the Northwoods memorandum's specific manufactured-casualty elements. The exact boundary between "Northwoods, rejected" and "Mongoose-era covert action, executed" is not fully clean in the public record. Whether any element of Northwoods made it into operational practice under a different name has been argued in both directions by historians.

The role of CIA-DoD coordination

The Northwoods package references the use of "a CIA proprietary organization" (a CIA-controlled front company) as the entity whose aircraft would be substituted with a drone. This indicates the JCS was contemplating CIA cooperation in the operation. The CIA's own knowledge of and reaction to the Northwoods package is not documented in any released CIA file from the period. Whether the agency was aware of the proposal in detail, and how it would have responded if asked to participate, remains open.

Why the document was declassified at all

The JFK Records Act mandated the release of documents that could illuminate the assassination and its context. Northwoods does not directly concern the assassination — it predates it by 20 months and was rejected. Why the document was nonetheless reviewed and released under the Act's terms, rather than withheld under one of the available national-security exemptions, is a procedural question with no public answer.

Primary material.

The Operation Northwoods documentary record is unusually accessible for a declassified case:

• The Northwoods memorandum itself, "Justification for US Military Intervention in Cuba," March 13, 1962. Full text available at the National Security Archive at George Washington University and at NARA's John F. Kennedy Assassination Records Collection. The document is unredacted in the released version.
• The signature page bearing Lemnitzer's name and the date.
• Related Caribbean Survey Group memoranda from January through March 1962, held in Joint Staff records at NARA, providing context for the proposal's development.
• Lemnitzer's personnel and reassignment records from late 1962, documenting the end of his JCS tenure.
• Bamford's annotated reproduction in Body of Secrets (2001), which provides the historical framing most often cited in subsequent treatments.
• The National Security Archive's online edition at nsarchive2.gwu.edu — the most accessible published version with editorial context.
