in the
1946 Argentine election, he directed US diplomats in Latin America to avoid supporting particular candidates in elections—lest they suffer due to the perceived association. He commented during the
1950 Guatemalan election:
At election time it is just political suicide to try to defend the United States... I think on the whole people in the other American Republics understand and support us, but it isn't good politics to say so at election time. We are a sort of punching bag during elections. Everybody likes to take a swing at us, and makes sure he does every time you say something.
Mann sought military assistance from Latin American countries during the
Korean War
The Korean War (25 June 1950 – 27 July 1953) was an armed conflict on the Korean Peninsula fought between North Korea (Democratic People's Republic of Korea; DPRK) and South Korea (Republic of Korea; ROK) and their allies. North Korea was s ...

[LaFeber, "From the Good Neighbor to Military Intervention" (1993), p. 169.]
Mann believed that nationalism and Communism were related problems, and sought to prevent both as part of efforts to prevent Latin
nationalization

is the process of transforming privately owned assets into public assets by bringing them under the public ownership of a national government or state. Nationalization contrasts with p ...
of resources. In a surprise to many observers, he agreed to secure US aid for Bolivia following the 1952
Bolivian revolution, partly as a reward for the new government's agreement to compensate US tin companies for nationalized assets.
Eisenhower administration
Policy shift
In 1952, Mann welcomed the incoming Eisenhower administration with a 42-page memo on US relations with Latin America. The memo argued that the main issue for the US in this region was not a Communist invasion, but the problem of US control over "readily accessible essential
strategic materials". These included
vanadium
Vanadium is a chemical element; it has Symbol (chemistry), symbol V and atomic number 23. It is a hard, silvery-grey, malleable transition metal. The elemental metal is rarely found in nature, but once isolated artificially, the formation of an ...

, resources which the US imported mostly from Latin America. Mann advocated swift US intervention to retaliate against nationalizations, as a show of force to deter similar actions by other countries. This memo was a source for NSC 144/1, representing the incoming Eisenhower administration's new policy on Latin America.
Guatemala
In Guatemala, Mann attended the inauguration of President
Jacobo Árbenz Guzmán and pronounced him a communist. Although he resisted early overtures by
United Fruit representatives to intervene, he opposed
Árbenz's land reform law, fearing that Guatemala would provide a test case for other nations. After the
CIA-backed military coup in 1954, Mann was recalled from Greece to Guatemala. He established
Norman Armour as the US ambassador and sought to bolster the new military government of
Castillo Armas. Mann reportedly gained de facto veto power over Guatemalan policy; after Mann had rejected a new oil law, Armas said he would come to "no final decision without consulting with Mr. Mann."
Mann later reflected that US operatives in Guatemala had an "illusion of omnipotence", saying in 1975:
We were on the crest of a wave and nobody, literally nobody on the Hill or anywhere else ever questioned our ability to do anything if we wanted to do it ndif we were willing to spend the money and the effort to do it.
Economic aid
In late September 1957 Mann moved to

, which had been planned by the CIA before Kennedy took office. He doubted the possibility of a popular uprising and, with Kennedy, opposed involvement by the US Air Force. He resigned his position at the State Department just weeks before the invasion took place in April 1961.
[LaFeber, "From the Good Neighbor to Military Intervention" (1993), p. 184.] In general, Mann felt that military action against Cuba would be too damaging for the US image. Instead, he supported economic sanctions to create suffering and dissatisfaction among the Cuban poor.

Lyndon B. Johnson
Lyndon Baines Johnson (; August 27, 1908January 22, 1973), also known as LBJ, was the 36th president of the United States, serving from 1963 to 1969. He became president after the assassination of John F. Kennedy, under whom he had served a ...
re-appointed Mann Assistant Secretary of State for Inter-American Affairs. On December 21, Johnson also made Mann the head of the
US Agency for International Development (USAID), an organization created by President Kennedy two years earlier. The double-appointment was opposed by the Kennedys and their liberal supporters, including Senator
Hubert Humphrey
Hubert Horatio Humphrey Jr. (May 27, 1911 – January 13, 1978) was an American politician who served from 1965 to 1969 as the 38th vice president of the United States. He twice served in the United States Senate, representing Minnesota from 19 ...
and advisor
Arthur Schlesinger Jr. Schlesinger wrote that Johnson's appointment of Mann constituted "a declaration of independence, even perhaps a declaration of aggression against the Kennedys." Members of the United States corporate establishment, generally felt they had a good relationship with Mann and supported the appointment.
Mann Doctrine
In March 1964, the new Johnson administration held a three-day policy conference for all U.S. diplomats in Latin America. On March 18, Mann gave a secret speech to U.S. officials which laid out the administration's policy for the region. Mann did not discuss the Alliance for Progress. His policy called for non-intervention against dictators if they were friendly to US business interests, but intervention against Communists regardless of their policies. The content of Mann's speech was leaked to the ''New York Times''. His comments were interpreted as prioritizing US economic interests over political reform, and the thrust of this policy became known as the "Mann Doctrine".
Brazil
Later that month, Mann supported the
military overthrow of the democratically elected government in Brazil, claiming a victory against Communism. Mann assisted this takeover directly by diverting US aid to Brazil away from the Goulart's central government. US operatives interpreted the March 18 Mann Doctrine as a "green light" for the coup to go forward. After the coup, Mann stated that "the frustration of Communistic objectives in Brazil was the single most important victory for freedom in the hemisphere in recent years".
Chile
In Chile, Mann ordered an intensive and coordinated campaign in favor of
Eduardo Frei against
Salvador Allende
Salvador Guillermo Allende Gossens (26 June 1908 – 11 September 1973) was a Chilean socialist politician who served as the 28th president of Chile from 1970 until Death of Salvador Allende, his death in 1973 Chilean coup d'état, 1973. As a ...

, Mann wrote:
Clearly, the September election will be determined by factors which are deeply rooted in the political, economic, and social fabric of the Chilean scene and by the campaign abilities of the major contenders. Given the consequences, however, if this major Latin American nation should become the first country in the hemisphere to freely choose an avowed Marxist as its elected president, the Department, CIA, and other agencies have embarked on a major campaign to prevent Allende's election and to support Frei, the only candidate who has a chance of beating him.
Mann described a ten-point plan, which included:
* threats of economic retaliation against Chile if Allende won;
* CIA and
USIA production and dissemination of
unattributed propaganda against Allende;
* $70 million in emergency loans to prop up the economy and reduce unemployment before the election; and
* secret contacts of US government and businesses with Chilean business, military, police, clergy, trade unions, and Masons, for the purpose of opposing Allende.
These efforts were successful in 1964 but
reversed in 1970.

René Barrientos Ortuño led a takeover of the popular

Dominican Republic
In the Dominican Republic, Mann labeled democratically elected President
Juan Bosch a communist and supported the
US invasion in 1965. In April 1965, Mann personally insisted on the production of a cable which would describe danger to American citizens in the Dominican Republic. At the same time, Mann pressured the military government to crack down on insurgents in
