President Eisenhower pledges support to South Vietnamese President Ngo Dinh Diem’s government and military forces in a letter on October 25, 1954. Eisenhower made it clear to Diem that U.S. aid to his government during Vietnam’s “hour of trial” was contingent upon his assurances of the “standards of performance [he] would be able to maintain in the event such aid were supplied.” Eisenhower called for land reform and a reduction of government corruption. Diem agreed to the “needed reforms” stipulated as a precondition for receiving aid, but he never actually followed through on his promises. Ultimately his refusal to make any substantial changes to meet the needs of the people led to extreme civil unrest and eventually a coup by dissident South Vietnamese generals in which Diem and his brother were murdered.
