Operation MONGOOSE: The Kennedy-Era Covert War Against Castro, 1961–1962.

What MONGOOSE was, in a paragraph.

Operation MONGOOSE was the operational name for the U.S. covert action program against the government of Fidel Castro, authorized by President John F. Kennedy on November 30, 1961, in a National Security Action Memorandum drafted under Attorney General Robert F. Kennedy's direction, and active from December 1961 through October 1962. Its formal title within the executive branch was "The Cuba Project"; "MONGOOSE" was a cryptonym applied by the CIA's operational staff. The program operated under the policy direction of a body called the Special Group (Augmented), a National Security Council subcommittee chaired by General Maxwell Taylor and including Robert Kennedy (Attorney General), Roswell Gilpatric (Deputy Secretary of Defense), John McCone (CIA Director from November 1961), McGeorge Bundy (National Security Advisor), Lyman Lemnitzer (Joint Chiefs of Staff Chairman until October 1962, then Maxwell Taylor in continuing role), and U. Alexis Johnson (Deputy Under Secretary of State). Program management on the White House side was Brigadier General Edward G. Lansdale, USAF, on detail to the Office of the Secretary of Defense. Operational management on the CIA side was William K. Harvey, head of the new CIA Task Force W, which superseded the agency's earlier WH/4 (Western Hemisphere Division Branch 4) and absorbed substantial portions of the existing anti-Castro infrastructure. Harvey reported to Richard Helms, the Deputy Director for Plans. The program's overall objective, stated in Lansdale's January 18, 1962 program review, was to "help the Cubans overthrow the Communist regime from within Cuba and institute a new government with which the United States can live in peace." Lansdale's program of action was structured in six phases, with the final phase — a Cuban uprising supported by U.S. military intervention — scheduled for October 1962. The operational measures included thirty-three discrete operations or "Mongoose teams" organized around sabotage, propaganda, agent infiltration, intelligence collection, and what the program's internal documents termed "executive action." The executive-action capability, code-named ZR/RIFLE, had been organized by William Harvey from late 1960 as a generic CIA assassination capability and was integrated into MONGOOSE in early 1962 as the program's mechanism for any operation against Castro personally. The most-documented strand of ZR/RIFLE's anti-Castro work was the agency's subcontract with the Chicago Outfit through the intermediary Robert Maheu — a contract initially developed in summer 1960 under the Eisenhower administration's CIA Office of Security under Sheffield Edwards, brought into Harvey's hands in spring 1962, and operating principally through John Roselli (Chicago Outfit representative), Sam Giancana (Chicago Outfit boss), and Santo Trafficante Jr. (Tampa-based Sicilian-Mafia figure with Cuba-resident connections from the pre-revolutionary period). The assassination methods documented in the surviving record and characterized in detail in the Church Committee Final Report Book V on "The Investigation of the Assassination of President John F. Kennedy: Performance of the Intelligence Agencies" (April 23, 1976) included: poison cigars; a contaminated diving suit prepared for delivery to Castro through American attorney James Donovan during his December 1962 hostage-exchange visits; an exploding seashell intended to be placed on a Castro snorkeling-area reef; a hypodermic-needle-loaded ballpoint pen prepared for the Cubela operation; contaminated fungus intended for application to the inside of Castro's diving suit; an attempt using Marita Lorenz, Castro's former girlfriend, to administer poison tablets; and a continuing covert relationship with Rolando Cubela Secades, a senior Cuban official codenamed AMLASH, whose pen-needle and rifle equipment was being delivered through the CIA in Paris at the very hour of the Kennedy assassination on November 22, 1963. The program also overlapped substantially with Operation Northwoods, the March 1962 Joint Chiefs of Staff false-flag proposal to manufacture a pretext for U.S. military intervention in Cuba, which the President rejected. MONGOOSE was suspended on October 30, 1962, by Kennedy's direct order following the Cuban Missile Crisis resolution; the Kennedy-Khrushchev understanding included an implicit U.S. commitment not to invade Cuba that constrained the program's operational logic. Subsequent anti-Castro operations continued under the Cuban Coordinating Committee through 1965 (operations including the AMWORLD project under Manuel Artime), but the integrated covert-action structure of MONGOOSE was not reconstituted. The most thorough public-record documentation of MONGOOSE comes from the Church Committee's Final Report Book V (1976), the CIA's own internal "Family Jewels" review (compiled May 1973, released 2007), the Lansdale Papers at the Hoover Institution, the Joint Chiefs of Staff records released through the Assassination Records Review Board (1994–1998), and the Foreign Relations of the United States volumes on Cuba 1961–1962. The JFK assassination retaliation hypothesis — that Castro, having learned of the assassination plots against him, ordered Kennedy's killing in November 1963 — is treated in the Church Committee Final Report Book V; the report concludes that the available evidence does not support the hypothesis but acknowledges that the question of whether the U.S. assassination plots against Castro contributed to the climate that produced the Kennedy assassination cannot be definitively foreclosed.

The documented record.

Origins: the Bay of Pigs and the November 30, 1961 authorization

The Bay of Pigs invasion of April 17–19, 1961, failed at substantial cost to the Kennedy administration's foreign-policy credibility and to the Cuban exile community that had carried the invasion's operational weight. Verified The April 22, 1961 Taylor Commission inquiry, conducted under Maxwell Taylor with Robert Kennedy, Admiral Arleigh Burke, and Allen Dulles, produced a report identifying institutional and tactical failures and recommending continued covert action against Castro on a restructured basis. Over the subsequent six months, the Kennedy administration's Cuba policy was reconstructed. The November 30, 1961 National Security Action Memorandum, drafted under Robert Kennedy's direction and signed by President Kennedy, authorized the Cuba Project. The accompanying instruction to General Lansdale — "Use our available assets... to help Cuba overthrow the Communist regime" — was the program's authorizing language [1][2].

The Special Group (Augmented) and the chain of command

The Special Group (Augmented) was a National Security Council subcommittee created specifically for MONGOOSE oversight, distinct from the standing 5412 Committee that handled routine covert-action approvals. Verified Its membership: General Maxwell Taylor (chair, as the President's Military Representative until October 1962, then in continuing role); Robert Kennedy (Attorney General); Roswell Gilpatric (Deputy Secretary of Defense); John McCone (Director of Central Intelligence from November 29, 1961); McGeorge Bundy (Special Assistant to the President for National Security Affairs); Lyman Lemnitzer (Joint Chiefs of Staff Chairman until October 1962); and U. Alexis Johnson (Deputy Under Secretary of State). The chain of command ran: Presidential authorization to Special Group (Augmented) for policy approval; Lansdale as program manager from the White House/OSD side; Harvey as operational chief on the CIA side through Task Force W; Helms as Deputy Director for Plans receiving Harvey's reporting; McCone as Director [1][3].

Lansdale's six phases

General Lansdale's January 18, 1962 program review — the so-called "Lansdale Program" memorandum — structured the operation in six phases. Verified Phase I (March 1962): action; build apparatus inside Cuba; intelligence operations. Phase II (April–July 1962): build-up; political opposition; sabotage and harassment. Phase III (August–September 1962): readiness for open revolt; cadre training. Phase IV (October 1962): open revolt with U.S. military support; "October 1962" is the explicit Phase IV month in Lansdale's program. Phase V (November 1962): consolidation. Phase VI (December 1962): installation of new government. The October 1962 timing of Phase IV is the central temporal fact of the program; it explains why MONGOOSE was running at peak intensity in the very weeks during which the Cuban Missile Crisis developed [1][3].

Task Force W and the JM/WAVE station

William King Harvey, a former FBI agent who had moved to the CIA in 1947 and had directed the Berlin Tunnel operation in 1955–1956, was appointed head of the new CIA Task Force W in February 1962. Verified Task Force W replaced the earlier Western Hemisphere Division Branch 4 (WH/4), absorbed the Bay of Pigs-era infrastructure, and operated principally out of two locations: Headquarters at Langley, and the JM/WAVE station at the South Campus of the University of Miami (a former Navy facility known to the local press as "Zenith Technical Enterprises"). JM/WAVE at its peak in 1962 employed approximately 400 American case officers and supported between 4,000 and 8,000 Cuban exile operatives, controlled a fleet of small boats and aircraft, and was the second-largest CIA station in the world. The JM/WAVE base of operations was a substantial open secret in the Miami exile community; it was the operational platform for nearly all anti-Castro action between 1961 and 1968 [4][5].

The thirty-three Mongoose teams

The MONGOOSE program at its peak organized thirty-three discrete operations or teams, each with its own cryptonym and operational target. Verified These covered sabotage of sugar mills, oil refineries, electrical generating stations, and harbors; propaganda operations including radio broadcasts and printed-leaflet airdrops; intelligence collection through agents infiltrated into Cuba on small boats from the Florida Keys; economic warfare through the encouragement of foreign-firm withdrawal from Cuba; and the executive-action component organized through ZR/RIFLE. The sabotage operations produced substantial physical damage at marginal costs; the propaganda operations had limited reach. The intelligence collection was the program's most-sustained operational success, providing the U.S. government with much of the pre-October 1962 ground-level intelligence on the Soviet missile build-up. The October 1962 photography that produced the missile-crisis disclosure came from U-2 overflights rather than from MONGOOSE-collected ground intelligence, but MONGOOSE-collected human-source reporting had been raising the missile question through the summer [3][4][5].

ZR/RIFLE and the executive-action capability

The CIA's interest in a generic executive-action capability predated MONGOOSE. Verified ZR/RIFLE was a program organized by William Harvey beginning in late 1960 at Richard Bissell's direction (Bissell being then the Deputy Director for Plans, prior to his post-Bay-of-Pigs removal), to develop a stand-alone assassination capability not associated with any specific target. Harvey's principal operational contact for ZR/RIFLE was an agent identified in the agency's records only as "QJ/WIN," a European national with criminal connections (his identity has been variously reported but never definitively documented). The program was distinct from the parallel mafia-subcontract anti-Castro effort, which had originated in summer 1960 under the CIA Office of Security under Sheffield Edwards, with operational management by Robert Maheu (a former FBI agent and CIA security contractor whose Las Vegas private investigation firm provided plausible deniability). In spring 1962, Harvey took over management of the Maheu-mafia channel and integrated it into ZR/RIFLE and through ZR/RIFLE into MONGOOSE. The mafia principals were John Roselli (the Chicago Outfit's Los Angeles representative; the principal contact with Maheu), Sam Giancana (Chicago Outfit boss; introduced to the operation as the source of operational support), and Santo Trafficante Jr. (Tampa-based, with pre-revolutionary casino interests in Havana and continuing connections to anti-Castro Cubans) [3][6][7].

The documented assassination attempts

The Church Committee Final Report Book V on "The Investigation of the Assassination of President John F. Kennedy" (April 23, 1976) and the parallel Interim Report on Alleged Assassination Plots Involving Foreign Leaders (November 20, 1975) document a series of assassination attempts against Castro, of varying levels of operational seriousness, that span the 1960–1965 period. Verified The poisoned-cigar attempts, originating in 1960 under Sheffield Edwards's Office of Security and continued under Harvey, involved the preparation and delivery to anti-Castro operatives of cigars treated with a botulinum-toxin preparation; the cigars were never delivered to Castro and the operational viability of the delivery vector was uncertain. The contaminated wetsuit/diving suit attempt, prepared in autumn 1962 under MONGOOSE auspices, involved the contamination of a diving suit's breathing tube with tuberculosis-causing bacteria and the boots with fungus, for delivery to Castro through American attorney James Donovan during his late-1962 hostage-exchange visits to Havana (Donovan was negotiating the release of the Bay of Pigs prisoners). Donovan, who was unaware of the contamination plan, delivered a different (uncontaminated) wetsuit as a personal gift; the contaminated suit was never delivered. The exploding-seashell plan involved the placement of an explosively-rigged seashell at a Castro snorkeling-area reef; the operational planning was abandoned as impractical. The ballpoint-pen hypodermic was prepared for the AMLASH (Cubela) operation. The contaminated-fungus material was an alternative diving-suit delivery vector. The Marita Lorenz attempt — Lorenz, a former Castro girlfriend, claimed she had been recruited by Frank Sturgis to deliver poison tablets to Castro in early 1960; the tablets, on her account, dissolved before delivery; the operational reality and Lorenz's own credibility are contested in the historiographic literature. The Rolando Cubela ("AMLASH") operation was substantively different in character — an effort to develop Cubela, a senior Cuban official disillusioned with Castro, as the inside-Cuba executor of a coup against Castro. The Cubela operation continued past MONGOOSE's formal termination; the operational meeting at which a CIA officer (Nestor Sanchez) delivered a poison-rifle and a pen-needle to Cubela in Paris took place on November 22, 1963 — the day of the Kennedy assassination [6][7][8].

The Operation Northwoods overlap

Operation Northwoods, covered in our separate file, was the March 13, 1962 Joint Chiefs of Staff false-flag proposal to manufacture a pretext for U.S. military intervention in Cuba. Verified Northwoods and MONGOOSE were institutional siblings: both originated from the Pentagon side of the same Cuba-policy moment, both passed through Lemnitzer's JCS, and both were briefed to the same Special Group (Augmented). Lansdale was the bridging figure between the two. Kennedy's rejection of Northwoods, communicated to Lemnitzer in mid-March 1962 by Secretary of Defense McNamara, did not formally terminate MONGOOSE, which continued on its own logic; but the two programs sat in adjacent and partially-overlapping institutional spaces [9].

The October 1962 standdown

The Cuban Missile Crisis — the October 14, 1962 U-2 photography of Soviet MRBM (R-12) sites in western Cuba, Kennedy's October 22 quarantine announcement, the October 24–28 brinkmanship period, and the October 28 Khrushchev radio statement agreeing to withdraw the missiles — collided with MONGOOSE in its most-intensive operational phase. Verified The MONGOOSE sabotage teams scheduled for late October 1962 were operating on cycles that pre-dated the missile crisis and were not coordinated with the diplomatic posture; on October 26, 1962, in the middle of the most acute period of the crisis, a MONGOOSE sabotage operation against a Cuban industrial target proceeded without high-level review, producing exactly the kind of escalation risk that the missile crisis's diplomatic management was attempting to avoid. President Kennedy, on October 30, 1962, issued a direct order suspending MONGOOSE operations. The Kennedy-Khrushchev understanding of October 28, formalized over subsequent weeks, included an implicit U.S. commitment not to invade Cuba; the operational logic of MONGOOSE, predicated on Phase IV's October 1962 U.S. military intervention, was rendered obsolete by the agreement. The program's formal wind-down extended through January 1963 [3][10].

The post-MONGOOSE successor programs

The 1963 Cuban Coordinating Committee, chaired at State Department level, took over coordination of post-MONGOOSE anti-Castro activity. Verified The principal successor operations included the AMWORLD project (codename for an autonomous Cuban exile leadership group under Manuel Artime, supported by the CIA from outside U.S. territory to provide additional plausible deniability), and the continued AMLASH (Cubela) operation. The integrated covert-action structure of MONGOOSE — Lansdale as White House manager, Harvey as CIA operational chief, the Special Group (Augmented) as policy body — was not reconstituted. Harvey himself was reassigned in mid-1963, partly in consequence of a clash with Robert Kennedy during the October 1962 crisis. The Cubela operation continued through November 1963, terminated finally after concerns about Cubela's operational security and the post-assassination institutional environment [3][8].

The competing institutional positions.

The Kennedy administration's position on MONGOOSE, as articulated in the surviving record and through subsequent statements by participants, has been complex. Claimed The position has held that MONGOOSE was a serious effort at covert action against the Castro government, undertaken in the context of established Cold War rivalry and in the immediate aftermath of the Bay of Pigs setback; that the program's sabotage, propaganda, and intelligence-collection components were legitimate covert-action measures; and that the assassination component, while real, was either not authorized at the Presidential level or was not communicated to the President with the level of specificity that would have constituted authorization. The question of whether President Kennedy or Robert Kennedy personally authorized the Castro assassination plots is the central contested question in the historiographic literature. The Church Committee's Interim Report (1975) found the documentary record on Presidential authorization "inconclusive" and noted the absence of direct documentary evidence of Presidential approval. The Church Committee's preferred interpretation — articulated in Senator Frank Church's separate statement — characterized the CIA assassination apparatus as a "rogue elephant" operating without clear Presidential direction. This interpretation has been substantially contested by historians of subsequent decades, who have argued for various degrees of Presidential (Kennedy or Kennedy-administration) knowledge of and tacit authorization for the assassination component [6][7].

The CIA's position, articulated through Harvey, Helms, and the Office of Security personnel involved in the mafia channel, has been that the Castro assassination effort was authorized at the appropriate Plans Directorate and Director level (Bissell to 1962; Helms through MONGOOSE; McCone as DCI), that the Special Group (Augmented) was informed in the relevant euphemistic language ("executive action," "removing Castro," "neutralization"), and that the program operated within the bounds of the authority transmitted through the chain. Claimed Helms's 1975 testimony to the Church Committee was that he had not personally informed President Kennedy of the Castro assassination plots in those terms; whether the President was informed in other terms (and inferred the substance), or whether the Special Group (Augmented) communications constituted the relevant authorization, is the question that the Church Committee did not resolve. Harvey's own contemporaneous documentation indicates a clear understanding within Task Force W that assassination was an authorized objective; whether this understanding accurately reflected the upstream authorization, or was a subordinate misreading, is in the historiographic dispute [3][6].

The position of Robert Kennedy, articulated in his lifetime principally through silence and after his death through the testimony of staff and associates, has been substantially contested. Disputed Robert Kennedy's role as the Attorney General driving the policy direction of MONGOOSE from the White House side is documented in the contemporaneous records. The Attorney General's contemporaneous knowledge of the specific Castro assassination plots is the contested question. The Church Committee's Interim Report found documentary evidence that Robert Kennedy had been told of the mafia-CIA connection in May 1962 (by FBI Director Hoover, in the context of an unrelated mafia investigation in which the FBI had discovered the CIA's use of Roselli and Maheu); Kennedy's reaction to this disclosure was contested. The Lansdale Papers and the McCone Papers contain partial documentation of Robert Kennedy's continuing involvement in MONGOOSE policy decisions through 1962; whether his policy direction encompassed approval of or direction toward the assassination component remains the subject of historiographic dispute [3][6][7].

The Castro government's position, articulated by Fidel Castro in interviews from the 1960s through his death in 2016, has been that the assassination plots against him were known to Cuban intelligence at the time and were systematically defeated through counterintelligence work. Claimed Castro's 1977 interview with Bill Moyers, his 1992 statements to U.S. delegations attending the Cuban Missile Crisis 30th-anniversary conference in Havana, and his subsequent statements, characterized the number of attempts against his life at 638. The 638 figure, advanced by Cuban intelligence officer Fabian Escalante, has not been independently verified; the actual count of operationally serious attempts is substantially lower (Escalante's count appears to include attempts at various stages of planning, including many that did not proceed beyond preliminary discussion). The Cuban position is that the documented attempts in the U.S. record are a subset of the actual program [11][12].

The unresolved questions.

The Presidential authorization question

Whether President John F. Kennedy personally authorized the Castro assassination plots is the central unresolved question. Disputed No direct documentary evidence of Presidential authorization survives in the released record. The available evidence is circumstantial: the President's documented involvement in MONGOOSE policy direction at the Special Group (Augmented) level; the use of euphemistic language in contemporaneous documentation that participants subsequently identified as encompassing assassination; the testimony of various participants about communications with or instructions from the President. The Church Committee in 1975 characterized the question as not definitively resolvable on the available evidence; subsequent declassifications through the ARRB process (1994–1998) and continuing JFK Records Act releases have not produced new evidence that resolves the question. The historiographic positions range from the "rogue elephant" reading (Church 1975) through varying degrees of inferred Presidential authorization to the "the President knew everything material" reading (advanced by some authors including David Talbot, Lamar Waldron). The question remains open [6][7][13].

The Robert Kennedy question

Robert Kennedy's personal direction of the MONGOOSE program from the White House side, and his contemporaneous knowledge of the assassination component, is the parallel and partly-derivative unresolved question. Disputed The Hoover-Kennedy May 1962 meeting at which the FBI Director informed the Attorney General of the CIA-mafia connection is documented; what Kennedy did with the information, and whether his subsequent direction of MONGOOSE continued to encompass the assassination component, is the contested question. The Lansdale Papers and the Hilsman Papers contain partial documentation; the Kennedy family papers at the JFK Library contain Robert Kennedy materials whose access has been substantially restricted [3][6][13].

The 638 figure and the actual count of attempts

The Cuban government's claim of 638 documented attempts on Castro's life has not been independently corroborated and substantially exceeds the count of operationally serious attempts documented in the U.S. record. Claimed The actual count of attempts that progressed beyond preliminary discussion to operational planning, based on the surviving U.S. record and the Cuban Intelligence accounts cross-referenced, is approximately a dozen. The discrepancy reflects in part the elasticity of the term "attempt" (preliminary discussion, operational planning, attempted execution, near-successful execution) and in part the propagandistic deployment of the 638 figure by Cuban officials. The empirical question of how many distinct serious attempts occurred has not been definitively resolved [11][12].

The William Harvey trajectory

Harvey's reassignment in mid-1963 to the CIA station in Rome, and his subsequent decline within the agency, has been variously interpreted. Disputed The contemporaneous explanation, in agency records, related to his clashes with Robert Kennedy during the October 1962 crisis (Harvey had continued certain MONGOOSE operations during the missile crisis that Kennedy had ordered suspended). The retrospective interpretation, advanced by some historians, has connected Harvey's reassignment to the post-MONGOOSE attempt to compartmentalize his knowledge. Harvey himself, who died in 1976, was substantially silent on the question in his lifetime. His widow's papers, accessible at the Hoover Institution, contain partial documentation [3][14].

The AMLASH/Cubela timing question

The Paris meeting at which Nestor Sanchez delivered the poison-pen-needle and the rifle to Rolando Cubela took place on November 22, 1963 — the day of the Kennedy assassination, at approximately the hour President Kennedy was being shot in Dallas. Verified The coincidence has been variously interpreted. The Church Committee's Final Report Book V (1976) characterized the timing as a coincidence and concluded that the available evidence did not support a causal connection between the AMLASH operation and Castro retaliation hypothesis. The contrary position — that Castro, having received information about the assassination plots against him through Cubela's connections (Cubela's loyalty was contested within Cuban intelligence) or through other channels, retaliated against Kennedy — has been advanced by various authors and has not been definitively foreclosed by the available evidence. The Church Committee found insufficient evidence to support the retaliation hypothesis but acknowledged that the U.S. assassination program against Castro had created the circumstances within which the retaliation hypothesis could not be definitively ruled out. The question is treated in our JFK Assassination file [6][7][8].

The full operational record

The CIA's MONGOOSE operational records have been substantially released through the Church Committee process (1975–1976), the Family Jewels release (2007), the JFK Records Act process (1992 onward), and the Assassination Records Review Board (1994–1998). Claimed Substantial portions remain in classified status under continuing national-security review. The 2017–2018 Trump-administration JFK Records Act batch releases produced additional MONGOOSE material; the 2025 (Trump second-term) directive to release remaining JFK files produced further releases, the full scope and content of which were still being analyzed by historians as of May 2026. Whether the remaining classified material would substantially alter the public understanding of MONGOOSE is not knowable until release [13][14].

Primary material.

The accessible primary record on Operation MONGOOSE is held at multiple locations:

• The National Archives (NARA), JFK Assassination Records Collection, holds the bulk of the released CIA MONGOOSE material through the JFK Records Act and ARRB processes, including Task Force W operational records, AMLASH file releases, and the Family Jewels review (2007).

Cases on this archive that connect.

Operation Northwoods (File 003) — the March 1962 Joint Chiefs of Staff false-flag proposal to manufacture a pretext for U.S. military intervention in Cuba. Northwoods and MONGOOSE were institutional siblings, both passing through Lemnitzer's JCS and both briefed to the same Special Group (Augmented). Lansdale was the bridging figure.

The JFK Assassination (File 006) — the November 22, 1963 event whose investigation has been substantially shaped by what the post-1975 Church Committee process revealed about the CIA's Castro assassination programs. The Castro-retaliation hypothesis remains a contested question; the AMLASH operation's November 22 timing is the central temporal coincidence.

MK-Ultra (File 001) — the contemporaneous CIA program of mind-control and chemical-interrogation research. The Office of Security under Sheffield Edwards, which originated the mafia-Castro channel, was the same office that administered ARTICHOKE and parts of MKULTRA. The institutional culture overlapped.

Project ARTICHOKE (File 014) — the predecessor to MKULTRA; the Office of Security under Sheffield Edwards was central to both ARTICHOKE and the MONGOOSE mafia-channel origins.

Operation Mockingbird (File 017) — the CIA's contemporaneous press-cultivation program. The press response to MONGOOSE-era anti-Castro activity, including the substantially absent reporting from 1961 to 1963, is the institutional artifact of the Mockingbird-era press-government relationship.

Operation AJAX (File 018) — the 1953 CIA-MI6 coup against Mosaddegh; the institutional precedent for U.S.-organized regime-change action that MONGOOSE was designed to replicate against Castro.

Planned: the Bay of Pigs as a standalone file, the AMLASH operation in detail, the Cuban Missile Crisis, the Assassination Records Review Board process.
