President Lyndon Johnson chose William Westmoreland, a distinguished veteran of World War II and the Korean War, to command the U.S. Military Assistance Command in Vietnam (MACV) in June 1964. Over the next four years, the general directed much of U.S. military strategy during the Vietnam War, spearheading the buildup of American troops in the region from 16,000 to more than 500,000. His strategy of attrition aimed to inflict heavy losses on North Vietnamese and Viet Cong forces using superior U.S. firepower, but resulted in a costly stalemate by late 1967. The enemy’s ambitious Tet Offensive in early 1968 cast serious doubt on Westmoreland’s claims of progress in the war effort, even as he called for some 200,000 more troops. Growing antiwar sentiment on the home front led President Johnson to halt bombing attacks on North Vietnam in March 1968, and in June he replaced Westmoreland in command of the MACV. Back in the United States, Westmoreland fought off criticisms of his conduct of the war (including a libel lawsuit against CBS News) and became a dedicated supporter of Vietnam veterans.
