Vietnamization – This was President Nixon's policy to withdraw the 540,000 U.S. troops in South Vietnam over an extended period, thus turning the war over to Vietnam. This would bring an end to the war in 1973.
Nixon Doctrine – The first challenge facing Nixon was the public uproar over Vietnam. He announced a policy called “vietnamization,” in which the 540,000 US troops would be removed from South Vietnam, and the South Vietnamese could then gradually take over the burden of fighting their own war. Thus the Nixon Doctrine evolved, which proclaimed that the US would honor its existing defense commitments but that in future nations would have to fight their own wars without US troops. Nixon thus sought not to end the war but to win it by other means, and although many complained, Nixon used VP Agnew to launch a propaganda campaign to win the support of the people.
