Thomas C. Mann#Mann Doctrine

Born in Laredo, an American city on the border with Mexico, Mann grew up speaking English and Spanish. His father was a lawyer and a Southern Baptist.LaFeber, "From the Good Neighbor to Military Intervention" (1993), p. 167.

He attended Baylor University and Baylor Law School, both in Waco, Texas, where he met his wife, the former Nancy Milling Aynesworth. They later had a son, Clifton Aynesworth Mann.{{Cite journal |date=May 1966 |title=Thomas C.

Mann was rejected from the Navy due to poor vision. He joined the Diplomatic Service, United States Department Of State in 1942, and was deployed to Montevideo in Uruguay to investigate Nazi shipping. In 1943, he was promoted to do this job across Latin America. He was involved in creating the 1945 Act of Chapultepec treaty for mutual defense of trans-American nations.

After unsuccessfully coordinating US opposition to Juan Perón 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, commenting "that if the Bolivians were complaining about spilling their blood for Yankees, a lot of Yankees were also complaining about American blood already being spilled in Korea for Bolivia and other countries of the hemisphere".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 of resources.LaFeber, "From the Good Neighbor to Military Intervention" (1993), p. 170. 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.LaFeber, "From the Good Neighbor to Military Intervention" (1993), p. 172. "After six months of careful watching, the United States recognized the new government, then stunned observers by actually giving economic aid, especially through tin purchases. Mann privately explained why aid could be sent to supposed revolutionaries: Bolivia had agreed to compensate former tin owners, especially the relatively few American owners, through arbitration; such arbitration could be an important precedent elsewhere in case of other nationalization; if Washington did not help, it would be charged with 'trying to bring chaos and starvation to Bolivia'; and U.S. bargaining leverage over Bolivia was great because of its purchasing power in the tin markets."

In 1952, Mann welcomed the incoming Eisenhower administration with a 42-page memo on US relations with Latin America. {{wikisource|NSC 144/1}} 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 as well as crude petroleum, 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.LaFeber, "From the Good Neighbor to Military Intervention" (1993), pp. 172–174.

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."LaFeber, "From the Good Neighbor to Military Intervention" (1993), pp. 176–177. The final quotation comes from [https://history.state.gov/historicaldocuments/frus1955-57v07/d23 Memorandum of a Conversation Between the Assistant Secretary of State for Inter-American Affairs (Holland) and President Castillo Armas, Guatemala City, February 14, 1955].

Mann later reflected that US operatives in Guatemala had an "illusion of omnipotence", saying in 1975:Brockett, "An Illusion of Omnipotence" (2002), pp. 91, 117.

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 [and] if we were willing to spend the money and the effort to do it.

In late September 1957 Mann moved to Washington, D.C., to become Assistant Secretary of State for Economic Affairs. Trans-American economic problems had created dissatisfaction and threatened to push Latin American countries away from the US. Secretary of State John Foster Dulles blamed an "economic war" waged by Moscow. Vice President Richard Nixon was mobbed by angry protestors in Venezuela and elsewhere.LaFeber, "From the Good Neighbor to Military Intervention" (1993), p. 178. Mann advocated policies of robust economic assistance, establishing the Inter-American Development Bank and promoting low-interest loans financed by the US government. Mann pushed for "a Marshall Plan for Latin America" which would also include private finance. Eisenhower concurred, and appointed Mann as Assistant Secretary of State for Inter-American Affairs in August 1960.LaFeber, "From the Good Neighbor to Military Intervention" (1993), pp. 179–180.

President John F. Kennedy promoted the Alliance for Progress, a centrist initiative to support Latin American economies and stave off communism through moderate reform.

Mann did not support the Bay of Pigs invasion, 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.Irving Molotsky, "[https://www.nytimes.com/1999/01/30/world/t-c-mann-87-a-maker-of-us-latin-policy.html T. C. Mann, 87, a Maker of U.S. Latin Policy]", New York Times, January 30, 1999. In general, Mann felt that military action against Cuba would be too damaging for the US image.Pérez, "Fear and Loathing of Fidel Castro" (2002), pp. 236. "Considerable attention was given to the repercussions of unilateral action against Cuba in Latin America. Assistant Secretary of State Thomas Mann was not alone in his early opposition to unilateral US efforts to remove Fidel Castro. '[I]f we were to go all out to get Castro,' Mann cautioned, 'it would obviously be what we would do. What would the effect be in the other Latin American countries? [W]e have to maintain a steady pressure and keep our motives well disguised in this business.' " Instead, he supported economic sanctions to create suffering and dissatisfaction among the Cuban poor.Pérez, "Fear and Loathing of Fidel Castro" (2002), p. 241. "Thomas Mann agreed, predicting that sanctions would 'exert a serious pressure on the Cuban economy and contribute to the growing dissatisfaction and unrest in the country'."

Kennedy appointed Mann United States Ambassador to Mexico where he successfully negotiated a settlement of the Chamizal border between the US and Mexican governments, caused by a shift in the Rio Grande.

On December 14, 1963, new President Lyndon B. Johnson 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 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."Stephen G. Rabe, The Most Dangerous Area in the World: John F. Kennedy Confronts Communist Revolution in Latin America; University of North Carolina Press, 1999; p. [https://books.google.com/books?id=ep84pGoEh0MC&pg=PA173 173]. Members of the United States corporate establishment, generally felt they had a good relationship with Mann and supported the appointment.LaFeber, "From the Good Neighbor to Military Intervention" (1993), p. 186. "The Kennedys and their supporters were stunned and bitter. Key liberals such as Senator Hubert Humphrey (D.-Minn.) tried to prevent the appointments. LBJ paid no attention. U.S. corporations operating in Latin America were delighted. 'The news of Tom Mann's appointment created more favorable reaction in Latin America than the launching of President Roosevelt's Good Neighbor policy,' cabled the vice president for Brown and Root Overseas, Inc., a powerful Texas firm with close ties to Johnson. 'I know him well and consider him the greatest.' Some liberals, including Senator Ernest Gruening (D.-Alaska) applauded the appointments in the hope that Mann could finally make Latin American policy work."Walker, "Mixing the Sweet with the Sour" (1994), p. 60.

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".LaFeber, "From the Good Neighbor to Military Intervention" (1993), pp. 187–188.Muller, "Dependent Economic Development" (1985), pp. 448–449.

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.LaFeber, "From the Good Neighbor to Military Intervention" (1993), pp. 190–191.Walker, "Mixing the Sweet with the Sour" (1994), p. 62. "While plans were underway to condemn Cuba for subversive activities, Secretary Mann announced the doctrine that bears his name. The United States would not inquire into the nature of regimes that were to receive military and economic assistance, an evaluation that several officials in the Kennedy administration had advocated. Support for social reforms had ceased to be a sine qua non for gaining Washington's favor." US operatives interpreted the March 18 Mann Doctrine as a "green light" for the coup to go forward.Muller, "Dependent Economic Development" (1985), p. 449. "A minority faction within the Army (estimated by one anti-Goulart general to have consisted in early March of about 10 percent of the higher officer corps-see Stepan, 1978: 122), which had favored a coup against Goulart since the beginning of his administration because of his alleged Communist tendencies, now decided to take the offensive. They were encouraged by American policymakers at the highest level in Washington, who gave an obvious and unequivocal 'green light' signal in announcing (but not for public consumption) the 'Mann Doctrine' on March 18,' and by the American Embassy in Brazil, which offered war material in case the coup should lead to civil war." 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".{{cite book|last1=Rabe|first1=Stephen G.|author-link=Stephen G.

In Chile, Mann ordered an intensive and coordinated campaign in favor of Eduardo Frei against Salvador Allende in the 1964 elections. In a May 1 memo to Secretary of State Dean Rusk, Mann wrote:[https://history.state.gov/historicaldocuments/frus1964-68v31/d253 253. Memorandum From the Assistant Secretary of State for Inter-American Affairs (Mann) to Secretary of State Rusk], Foreign Relations of the United States 1964–1968, Volume XXXI: "South and Central America; Mexico", Document 253. Cited in Power, "Engendering of Anticommunism and Fear" (2008), p. 934.

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:Power, "Engendering of Anticommunism and Fear" (2008), pp. 934–935.

• 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.LaFeber, "From the Good Neighbor to Military Intervention" (1993), p. 190. "During the 1964 Chilean elections, Mann paid little attention either to that principle or to his lesson, learned during the Argentine election of 1946, that U.S. interference in foreign political campaigns usually backfired. Eduardo Frei, a moderate reformer, ran against Salvador Allende, suspected of Marxist leanings and, as Mann phrased it, 'extremist supporters'. The U.S. economic stake was huge, especially in industry and in copper mines that Washington feared Allende might nationalize if he won. Mann ordered complete support of Frei, threatened economic retaliation of Allende triumphed, and wanted 'no doubt in Chile as to where the United States stands.' Frei won, but the Allende problem was only delayed for six years."

In Bolivia, when General René Barrientos Ortuño led a takeover of the popular Revolutionary Nationalist Movement (MNR) government, which had been in power for twelve years, Mann secured aid for the new military government.LaFeber, "From the Good Neighbor to Military Intervention" (1993), p. 191. "The generals' success and the Mann doctrine were also played out in Bolivia and Argentina. In Bolivia, Mann (and key U.S. congressional leaders) became critical of, and began distancing the United States from, Paz Estensaro's formerly revolutionary MNR party. When the military seized power in 1964, opened the door to foreign investment, promised agrarian reforms, and smashed urban labor demands, Mann responded with aid."

Mann later served in Panama during a period of intense agitation waged by Panamanians against the Panama Canal Zone. Mann began some successful negotiations with Panama, but was undercut by Johnson, who did not want to capitulate for political reasons.LaFeber, "From the Good Neighbor to Military Intervention" (1993), p. 192.

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 Santo Domingo. Mann described the popular rebellion as Communist infiltration enabled by Castro and supported the U.S. invasion as a necessary response.LaFeber, "From the Good Neighbor to Military Intervention" (1993), pp. 193–194.

Mann became the Undersecretary of State for Economic Affairs in 1965. He was bestowed the President's Award for Distinguished Federal Civilian Service by President Johnson in 1966. This is the highest award that can be given to a career civilian employee of the federal government. Mann was cited as having "represented the United States with outstanding judgment, initiative, intelligence, and vision."{{Cite journal |date=June 1966 |title=Tom Mann Receives President's Award |url=https://babel.hathitrust.org/cgi/pt?id=uiug.30112108168821&seq=415 |journal=State Department |pages=19 |via=Hathitrust}} He resigned from the State Department in June of 1966 and served as president of the Automobile Manufacturer's Association from 1967 through 1971.John Henrichs, "Ex-U.S. Ambassador Thomas C.
