President Johnson and General Westmoreland
President Lyndon Johnson, left, confers with General William Westmoreland. General Westmoreland commanded U.S. military operations from 1964 to 1968 during the Vietnam War. He supported escalating troop levels and requested that U.S. troops participate in combat missions. As U.S. casualties began to mount in 1966, he came under increasing criticism. He then served as Army Chief of Staff from 1968 to 1972.
