Nixon said Vietnamization had two components. The first was "strengthening the armed force of the South Vietnamese in numbers, equipment, leadership and combat skills", while the second was "the extension of the pacification program [i.e. military aid to civilians] in South Vietnam." To achieve the first goal, U.S. helicopters would fly in support; however, helicopter operations were too much part of ground operations to involve U.S. personnel.[clarification needed] Thus, ARVN candidates were enrolled in U.S. helicopter schools to take over the operations. As observed by Lieutenant General Dave Palmer, to qualify an ARVN candidate for U.S. helicopter school, he first needed to learn English; this, in addition to the months-long training and practice in the field, made adding new capabilities to the ARVN take at least two years. Palmer did not disagree that the first component, given time and resources, was achievable. However: "Pacification, the second component, presented the real challenge...it was benevolent government action in areas where the government should always have been benevolently active...doing both was necessary if Vietnamization were to work."
The policy of Vietnamization was ultimately a failure as the improved ARVN forces and the reduced American and allied component were unable to prevent the fall of Saigon and the subsequent merger of the north and south, to form the Socialist Republic of Vietnam.
After discussing the matter with Assistant Secretary of State William Bundy and Secretary of Defense Robert McNamara, a message was sent. Ho said he would be willing to negotiate if the U.S. bombing of North Vietnam under Operation Rolling Thunder ceased. Mai Van Bo, Hanoi's diplomatic representative in Paris, was named a point of contact. Since Hanoi would not communicate with an American official without a bombing halt, Kissinger served as an intermediary. Johnson made a speech in San Antonio on September 29, offering the possibility of talks. They were rejected, although brought up again in 1967.
End of Americanization
The departure of Lyndon B Johnson did not end the war; rather, it spread throughout Southeast Asia. The Tet Offensive (1968) was a political and media disaster. Newsman Walter Cronkite announced that he saw a stalemate as the best case scenario for the Tet Offensive. Other members of the press added to the call to retrench (reduce costs and spending). President Johnson's popularity plummeted and he announced a bombing halt on March 31, simultaneously announcing he would not run for re-election. Though he had low expectations, on May 10, 1968, Johnson began peace talks between U.S. and North Vietnamese in Paris. The war, however, continued.
