On 9 June, President Johnson replaced Westmoreland as commander of MACV with General Creighton W. Abrams. Although the decision had been made in December 1967 and Westmoreland was made Army Chief of Staff, many saw his relief as punishment for the entire Tet debacle. Abrams' new strategy was quickly demonstrated by the closure of the "strategic" Khe Sanh base and the ending of multi-division "search and destroy" operations. Also gone were discussions of victory over North Vietnam. Abrams' new "One War" policy centered the American effort on the takeover of the fighting by the South Vietnamese (through Vietnamization), the pacification of the countryside, and the destruction of communist logistics. The new administration of President Richard M. Nixon would oversee the withdrawal of U.S. forces and the continuation of negotiations.
