How did Paul Potters The Incredible War speech Johnsons explanation of why we were in Vietnam?

Paul Potter's "The Incredible War" speech emphasized the moral and ethical implications of the Vietnam War, arguing that U.S. involvement was driven by a misguided sense of patriotism and a failure to recognize the suffering caused by the conflict. He criticized the war as a manifestation of a broader systemic issue within American society, where violence and militarism overshadowed genuine humanitarian concerns. Johnson's explanation for the war, on the other hand, framed it as a necessary effort to contain communism and support a struggling ally, reflecting a more traditional geopolitical rationale. Together, the two perspectives highlight a profound tension between moral considerations and political motivations in the context of the Vietnam War.
