Thomas Clifton Mann (November 11, 1912 – January 23, 1999) was an American diplomat who specialized in Latin American affairs. He entered the U.S. Department of State in 1942 and quickly rose through the ranks to become an influential establishment figure. He worked to influence the internal affairs of numerous Latin American nations, typically focusing on economic and political influence rather than direct military intervention. After Lyndon B. Johnson became president in 1963, Mann received a double appointment and was recognized as the U.S. authority on Latin America. In March 1964, Mann outlined a policy of supporting regime change and promoting the economic interests of U.S. businesses. This policy, which moved away from the political centrism of Kennedy's Alliance for Progress, has been called the Mann Doctrine. Mann left the State Department in 1966 and became a spokesperson for the Automobile Manufacturer's Association.

Early life

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. Mann graduated from law school in 1934 and took a job at his father's law firm.LaFeber, "From the Good Neighbor to Military Intervention" (1993), p. 168. He held various posts, as a lawyer in Laredo, in 1934 to 1942.

Early career 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.

Truman administration

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."

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 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.

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."LaFeber, "From the Good Neighbor to Military Intervention" (1993), pp. 176–177. The final quotation comes from 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.

Economic aid

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.

Kennedy administration

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, "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.

Johnson administration

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. 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.

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