Among his many cartoons about the Vietnam War (1965-1973), Herb Block drew this symbolic warning about the United States being in over its head during the Tet Offensive. North Vietnamese forces made their bold assault in late January of 1968 with the aim of toppling the Saigon government and obliterating U.S. hopes in the region. The Tet Offensive did not prove decisive militarily, but it added to American doubt about the war. Shown here is a larger-than-life Uncle Sam, hoisting his rifle aloft and slipping into the morass of southeast Asia. The face of Block's Uncle Sam embodied the American anxiety and ambivalence about the Johnson administration's war policies.
