Nixon Doctrine

The Nixon Doctrine (also known as the Guam Doctrine) was put forth during a press conference in Guam on 25 July 1969 by US President Richard Nixon and later formalized in his speech on Vietnamization on November 3, 1969. The Doctrine stated that each ally nation was in charge of its own security in general, but the United States would act as a nuclear umbrella when requested. It implied the intentions of Nixon shifting the direction on international policies in Asia, especially aiming for Vietnamization of the Second Indochina War (1955-1975), known as the Vietnam War in America.
