Alberto Lleras Camargo

Alberto Lleras Camargo (July 3, 1906 - January 4, 1990) served as Colombia's president twice (August 7, 1945 - August 7, 1946 and August 7, 1958 - August 7, 1962) and as the first secretary-general of the Organization of American States (April 30, 1948 - August 1, 1954), and was a central member of Nelson Rockefeller's inter-American political network from the Chapultepec conference of 1945 onward. At Chapultepec and at the San Francisco founding conference of the United Nations, he coordinated votes and drafted resolutions alongside Rockefeller's US delegation. During his second Colombian presidency, he cooperated with both the Alliance for Progress and the counterinsurgency strategy that General William P. Yarborough's 1962 mission operationalized in Colombia, accepting Green Beret advisers and US backing while the Rockefeller network's IBEC and AIA operated in his country's Cauca Valley.

Early Career and Rise to Foreign Minister

Born into a middle-class Bogotá family, Lleras Camargo briefly attended university before entering Liberal journalism and politics. He was elected to Colombia's Congress in 1930. Under the first term of President Alfonso López Pumarejo (1934-1938), he became Colombia's youngest interior minister. He served as Colombian Ambassador to the United States from May 1943 to October 1943, then returned to serve as Minister of Government under López Pumarejo's troubled second term (1942-1945). On February 12, 1945, he was appointed Minister of Foreign Affairs, the position from which he represented Colombia at both the Chapultepec conference and the San Francisco UN conference that same year.

Chapultepec and the Rockefeller Network

Alberto Lleras Camargo was identified by Nelson Rockefeller as one of his most reliable Latin American allies as early as the Chapultepec conference in Mexico City, which ran from February 21 to March 8, 1945. As Colombia's foreign minister, he represented his country at the Inter-American Conference on Problems of War and Peace, where the Act of Chapultepec established the mutual defense framework that would become the template for the Rio Treaty and then the OAS. At Chapultepec, alongside Galo Plaza of Ecuador and Mexico's Ezequiel Padilla, Lleras Camargo acted in regular concert with Rockefeller's U.S. delegation. He joined Adolf Berle and Rockefeller in drafting the key resolution to bring Argentina back into the inter-American fold.¹

At the San Francisco UN conference in 1945, Lleras Camargo (serving as Colombia's foreign minister) was among the Latin American leaders Rockefeller used to manage the votes of the Latin American bloc. Soviet Foreign Minister Vyacheslav Molotov specifically denounced Lleras Camargo by name for obstructing resolutions at the conference.

When López Pumarejo resigned in July 1945, the Colombian Senate elevated Lleras Camargo to acting president at age thirty-eight, making him one of the youngest men to hold that office. He completed López's term through August 7, 1946, when Conservative Mariano Ospina Pérez was elected president.

OAS Secretary-General

Lleras Camargo became the first secretary-general of the Organization of American States when it was formally constituted at the Ninth International Conference of American States in Bogotá in April 1948, elected unanimously on April 30, 1948. He served in that capacity until August 1, 1954. This position, which Rockefeller had envisioned for the organization he helped design through the Act of Chapultepec and the Rio Treaty, gave Lleras Camargo institutional command of the inter-American system during its formative years.

He was also a trustee of the Rockefeller Foundation, a relationship documented through at least the 1968-1969 board year, formalizing his institutional alignment with Rockefeller interests.²

The National Front Agreements (1956-1958)

During the military dictatorship of General Gustavo Rojas Pinilla (1953-1957), Lleras Camargo traveled to Spain to negotiate with exiled Conservative leaders. On July 24, 1956, he signed the Pact of Benidorm with former Conservative president Laureano Gómez, who had gone into exile in the coastal town of Benidorm. The pact committed both Liberal and Conservative parties to collaborate against the Rojas Pinilla dictatorship and to an extended period of bipartisan cooperation.

Following the collapse of the Rojas Pinilla regime, Lleras Camargo and Gómez met again and signed the Declaration of Sitges on July 20, 1957, creating the constitutional framework for the National Front (Frente Nacional). The Sitges agreement established equal sharing of congressional, administrative, and diplomatic positions between the two parties, with the presidency alternating between Liberal and Conservative candidates in successive four-year terms for sixteen years (1958-1974). A national plebiscite ratified the National Front arrangement in December 1957.

In May 1958, Lleras Camargo was elected president as the first National Front president, taking office on August 7, 1958.

CIA Operational Approval (1958)

Declassified CIA files, released by the Trump administration in 2025 as part of the JFK assassination records, document that the CIA granted an "Operational Approval" on February 24, 1958, "for the utilization of LLERAS in supporting a special operation." This occurred before Lleras Camargo's election as president in May 1958. The files note that "there had reportedly been no operational interest in him since his election to the presidency." The nature of the proposed special operation is not described in the available documentation.³

Second Colombian Presidency (1958-1962)

Lleras Camargo returned to the Colombian presidency under the National Front power-sharing arrangement. His second presidency (August 7, 1958 - August 7, 1962) coincided with the early Alliance for Progress years and the intensifying Cold War competition in Latin America following the Cuban Revolution.

He was particularly anxious about Colombia's economic vulnerabilities. Coffee prices, Colombia's principal export, fell during the U.S. recession of 1960. As export earnings declined and debt payments to American and European banks triggered inflation, Lleras Camargo worried that this would strengthen rural guerrillas sympathetic to the Cuban revolutionary example. His government faced "peasant republics" in the valleys of Marquetalia, Sumapaz, and El Pato, which had survived since Colombia's decade-long La Violencia civil war.⁴

Early in his term, the State Department monitored threats to his government. A December 1, 1958 memorandum from Deputy Assistant Secretary of State (Snow) to Under Secretary of State Robert D. Murphy (classified Secret, drafted by Albert H. Gerberich) warned of danger to "a violent overthrow of the democratic National Union Government headed by Dr. Alberto LLERAS Camargo," identifying General Rojas Pinilla's return to Colombia on October 12, 1958 and the loyalist networks still supporting him as an active destabilization threat.⁵

When Adolf Berle visited Colombia in February 1961, lining up hemispheric support for the planned Bay of Pigs invasion, Lleras Camargo had a ready shopping list: he wanted small arms and helicopter gunships to deal with the guerrilla-held enclaves, which the Eisenhower administration's CIA-Pentagon Survey Team had already advised him to suppress. Berle recorded that Lleras Camargo wanted U.S. help transforming his army, trained for conventional Normandy-style invasions, into a force capable of counterinsurgency against "bandits in the high hills."⁶ This conversation is documented in FRUS 1961-63, Volume XII (Cuba), Document 48 (February 25, 1961).

Colombia's foreign minister Julio Cesar Turbay delivered a memorandum on May 6, 1961, outlining Colombia's position on the Cuban situation following the Bay of Pigs failure. Ambassador Wells reported to the State Department (Telegram 518 from Embassy Bogotá, May 6, 1961) that President Lleras Camargo "fully approved" the memorandum's contents and had been consulted by phone while Wells was present. The memorandum proposed convening the Inter-American Economic and Social Council to define threats to hemispheric security including "Soviet bases, nuclear weapons, arms shipments, subversion" and to establish procedures for collective defense.⁷

On September 27, 1961, Colombia submitted an urgent request for additional internal security aid. On November 1, 1961, President Kennedy signed a formal determination authorizing internal security aid to Colombia, documented in FRUS 1961-63, Volume XII, Document 57.⁸

Kennedy made the first working visit by a sitting U.S. president to Colombia on December 17, 1961, welcomed by Lleras Camargo at El Dorado Airport in Bogotá. The two leaders met that evening at the San Carlos Palace. Despite the Alliance for Progress framing, Cuba dominated the agenda: Lleras Camargo had severed Colombia's diplomatic ties with Cuba eight days before Kennedy's arrival, after Fidel Castro publicly denounced the Colombian president as "a miserable traitor." The Kennedy-Lleras meeting on December 17 covered "Developments in the Dominican Republic; planning for Foreign Ministers meeting on Cuban problem" (FRUS 1961-63, Volume XII, Document 58).⁹

Kennedy made Colombia the laboratory for the Alliance for Progress's twin approach of liberal economic reforms and military counterinsurgency. Rockefeller's IBEC was already invested in the Cauca Valley; his AIA was running agricultural credit programs there. The combination of Rockefeller private investment, Lleras Camargo's political reliability, and Kennedy's Alliance funding made Colombia the flagship case for "nation-building" in Latin America. On April 11, 1962, the United States approved its first "Program Loan" to Colombia for $30 million, days before the Colombian presidential election.¹⁰

The Yarborough Mission and Counterinsurgency Framework

Brigadier General William P. Yarborough, commander of the U.S. Army Special Warfare Center at Fort Bragg, visited Colombia from February 2 to February 13, 1962, accompanied by 7th Special Forces Group commander Colonel Clyde R. Russell and Lieutenant Colonel John T. Little (G-3, Special Warfare Center). The mission's objectives were to assess the violence problem, evaluate military counterinsurgency effectiveness, and recommend appropriate mobile training teams.

Yarborough's team found "a lack of central planning, coordination, and intelligence dissemination" hindering operations at all levels. His formal report, "U.S. Army Special Warfare Center Report, Visit to Colombia," dated February 26, 1962, recommended delineating responsibilities between military and police forces, establishing collaborative intelligence sharing, deploying mobile training teams (MTTs) for psychological warfare, civic action, air support, and intelligence, and sending five Special Forces Operational Detachment Alphas (ODAs) to work with engaged Colombian battalions. The classified annex to this report recommended that a "paramilitary, sabotage and/or terrorist" structure be built to "execute activities against known communist proponents."¹¹

Following the Yarborough visit, a Colombia Internal Defense Plan was drafted between May and June 1962 by a country team task force at the U.S. Embassy in Bogotá. Lleras Camargo's term ended on August 7, 1962; his successor León Valencia formally presented the integrated defense plan under Plan Lazo, which launched in October 1962 as Colombia's national counterinsurgency campaign. The plan committed seventy-five percent of the Colombian military to counterinsurgency operations.

Kennedy's farewell conversation with Lleras Camargo on September 27, 1962, covered "Coffee Agreement; Alliance for Progress" (FRUS 1961-63, Volume XII, Document 63), occurring weeks before Lleras's term ended and the Yarborough recommendations were formally implemented.¹²

SIL and Missionary Programs

Both Lleras Camargo and Galo Plaza helped William Cameron Townsend establish the Summer Institute of Linguistics in South America, providing the political backing that SIL needed to operate in their countries.¹³
