Dean Gooderham Acheson

Dean Acheson was Secretary of State during the consolidation of the early Cold War, from 1949 to 1953. He helped connect the economic reconstruction of wartime allies to a growing network of security commitments, with Europe at the center of his strategy. 3

Dean Acheson brought the proposed security treaty with Australia and New Zealand to President Harry Truman for review on July 10, 1951. His Washington memorandum credited John Foster Dulles with completing the negotiations and requested a discussion at the next National Security Council meeting. On September 1, Acheson joined the American signatories at San Francisco, alongside Australian ambassador Percy Spender and New Zealand ambassador Carl Berendsen. 1, 2

Acheson trained at Yale and Harvard Law School, clerked for Justice Louis Brandeis, and practiced law in Washington before entering government. His State Department work began in 1941 with economic affairs, including the oil embargo against Japan. After the war, he served as under secretary and participated in negotiations establishing international relief, food, and financial institutions. 3

As secretary of state from 1949 to 1953, Acheson supported NATO and the reconstruction of Japan as part of American policy during the Cold War. He continued advising presidents after leaving office, including during the Cuban missile crisis and the Vietnam War. He died in 1971. 3

Acheson supported NATO and efforts to tie western Germany to the Western powers, while the Chinese Communist victory and the Soviet atomic test of 1949 sharpened the administration’s perception of danger. He asked Paul Nitze’s Policy Planning Staff to review American strategy. The resulting NSC-68 recommended a major expansion of military capabilities alongside political and economic measures to contain Soviet power. 3, 4

The outbreak of the Korean War in June 1950 strengthened the case for that expansion and turned an initially disputed proposal into a guide for policy. Acheson simultaneously faced domestic attacks over the Communist victory in China and the retreat of the Nationalists to Taiwan. He regarded Soviet power as both ideological and geopolitical; his response combined alliances and reconstruction with a substantially larger American military commitment abroad. 3, 4
