What was the initial public feelings in the US regarding US involvement in Vietnam?

Initially, public feelings in the U.S. regarding involvement in Vietnam were largely supportive, as many Americans viewed the conflict through the lens of the Cold War and the desire to contain communism. The government portrayed the war as a necessary effort to support South Vietnam against communist aggression. However, as the war escalated and casualties increased, public sentiment began to shift, leading to widespread protests and growing anti-war sentiment by the late 1960s. This shift reflected broader concerns about the morality and effectiveness of U.S. military intervention.
