to supplement the playing of the recording. Allegedly, this acted as a catalyst for 150 Viet Cong leaving their positions. Leaflets were also used to amplify this scare tactic. Vietnam 1970 and after With its "Vietnamization" doctrine, proclaimed in early 1969, the Nixon administration began the gradual withdrawal of the United States from ground combat in South Vietnam. The end goal of this was to strengthen the military of South Vietnam. An expanded program of irregular operations in the eastern Panhandle was more productive. There was a lot of pressure for Nixon to withdraw from Indochina on the home front. Johnson's bombing of North Vietnam in 1968 really got backlash from the citizens back in America. There were a lot of protests all over the United States because of this. Even though the war was ending in Vietnam, protestors in the United States were still going crazy as the troops were returning from the battlefield. During the Nixon Presidency, domestic pressure to withdrawal from Indochina exponentially increased. However, Nixon was determined to escape the embarrassment of an American military defeat in Vietnam. Needing to rectify the aggravated electorate and ensure the prospects of shaping the settlement in Vietnam from a position of strength, Nixon and Kissinger turned to the CIA. Kissinger ordered the CIA to carry out “high political and psychological impact actions against military targets in North Vietnam.” The Agency sponsored Laotian guerrillas to erode the enemy's confidence in the security of the trail network.

The success of these operations enticed the CIA station in Vientiane to adopt them as a staple of its agenda. The change of government's Cambodia in March 1970 signaled an opportunity to expand the Commando Raider operations. The CIA gathered more intelligence pertaining to the specifics of troop movements and the location of NVA supplies. Raids to destroy these supplies became common. The CIA focused on the complete interdiction of the trail system that extended through Laos and Cambodia. While many of these raids were successful, it was a futile operation. The “means [were] inadequate to the end.” The CIA spent a great amount of resources and energy into preparing these raids, collecting intelligence, and carrying out attempts to further undermine the enemy now defeating them.
