True. The Tet offensive was a turning point in the war because it helped cement U.S. public opinion against the war. Many in the U.S. thought America was winning the war at the beginning of 1968. But when the Communist forces were able to muster such a large force against U.S. troops, General Westmoreland, the commander in charge of the Vietnam War, requested an additional 206,000 U.S. troops. Americans began asking the question, "Why do we need so many more troops if we are winning the war?" In addition, battle scenes and TV images of casualties were shown on the nightly news and finally,CBS anchorman Walter Cronkite, "the most trusted man in America", said the war should end. The costs of continuing were too high. This forced President Lyndon Johnson to announce that he would not be running for another term as president setting the stage for the eventual withdrawal of American troops from Vietnam.
