Answer: Though President Nixon expanded the war in Vietnam into Laos and Cambodia, his administration pursued a policy of Vietnamization, which aimed at reducing the number of American troops in the war.
Explanation: Vietnamization refers to the doctrine of President Richard Nixon from the time of the Vietnam War, according to which US forces would gradually withdraw from Vietnam and leave the defense of South Vietnam to the Vietnamese. At the same time, America would send modern weapons, equipment, advisers and financial aid to South Vietnam to compensate for the departure of their troops.
