USA HISTORY

Detailed explanation-1: -The Nixon Doctrine (also known as the Guam Doctrine) was put forth during a press conference in Guam on July 25, 1969, by President of the United States Richard Nixon and later formalized in his speech on Vietnamization of the Vietnam War on November 3, 1969.

Detailed explanation-2: -Vietnamization was a policy of the Richard Nixon administration to end U.S. involvement in the Vietnam War through a program to “expand, equip, and train South Vietnamese forces and assign to them an ever-increasing combat role, at the same time steadily reducing the number of U.S. combat troops".

Detailed explanation-3: -Publicly, Nixon said his strategy was a combination of negotiating and Vietnamization. In fact, he began the withdrawals even before he issued his secret ultimatum to the Communists, and he continued to announce partial troop withdrawals throughout his first term.

Detailed explanation-4: -The phrase is a variation on a campaign promise Nixon made in 1968: “I pledge to you that we shall have an honorable end to the war in Vietnam.” The Accords specified that a ceasefire would take place four days later.
