The Nixon Doctrine was put forth in a press conference in Guam on July 25, 1969 in which he stated that the United States henceforth expected its Asian allies to take care of their own military defense. This was the start of the "Vietnamization" of the Vietnam War. The Doctrine argued for the pursuit of peace through a partnership with American allies.

In Richard Nixon's own words (Address to the Nation on the War in Vietnam November 3, 1969)

  • First, the United States will keep all of its treaty commitments.
  • Second, we shall provide a shield if a nuclear power threatens the freedom of a nation allied with us or of a nation whose survival we consider vital to our security.
  • Third, in cases involving other types of aggression, we shall furnish military and economic assistance when requested in accordance with our treaty commitments. But we shall look to the nation directly threatened to assume the primary responsibility of providing the manpower for its defense.
