Answer:
Nixon Doctrine
Step-by-step explanation:
During his presidential campaign of 1969, Richard Nixon promised to extricate the US from Vietnam on honorable terms. It was later known as the "peace with honor" approach. The more formal term is the Nixon Doctrine - each US president must formulate his own foreign policy doctrine - that states that the US would honor its defense commitments but in the future, Asian nations and others would have to fight their own wars without the support of large numbers of American troops.
