In the time I was there, the committee held hearings on such subjects as attitudes of Americans toward foreign policy, China-U.S. relations, possible conflicts between U.S. domestic goals and foreign policy, the impact of the dispute between China and the Soviet Union on the Vietnam conflict, and the psychological aspects of international relations. Distinguished critics of our policy appeared, people like Harrison Salisbury of the New York Times; George Kennan, former ambassador to the USSR and author of the idea of “containment” of the Soviet Union; Edwin Reischauer, former ambassador to Japan; distinguished historian Henry Steele Commager; retired General James Gavin; and professor Crane Brinton, an expert on revolutionary movements. Of course, the administration sent up its witnesses, too. One of the most effective was Undersecretary of State Nick Katzenbach, who had a leg up with me at least, because of his civil rights work in President Kennedy’s Justice Department. Fulbright also met privately with Secretary of State Dean Rusk, usually for early-morning coffee in Fulbright’s office. I found the dynamics between Rusk and Fulbright fascinating. Fulbright himself had been on Kennedy’s short list for secretary of state. Most people thought he was eliminated because of his anti–civil rights record, especially his signing of the Southern Manifesto. Rusk was also a southerner, from Georgia, but he was sympathetic to civil rights and had not faced the political pressure Fulbright had, since he was not in Congress but a member of the foreign policy establishment. Rusk saw the Vietnam conflict in simple, stark terms: It was the battleground of freedom and communism in Asia. If we lost Vietnam, communism would sweep through Southeast Asia with devastating consequences. I always thought the dramatically different ways Fulbright and Rusk viewed Vietnam were due in part to the very different times when they were young Rhodes scholars in England. When Fulbright went to Oxford in 1925, the Treaty of Versailles ending World War I was being implemented. It imposed harsh financial and political burdens on Germany, and redrew the map of Europe and the Middle East after the collapse of the Austro-Hungarian and Ottoman empires. The humiliation of Germany by the victorious European powers, and the postwar isolationism and protectionism of the United States, reflected in the Senate’s rejection of the League of Nations and the passage of the Smoot-Hawley Tariff Act, led to an ultra-nationalist backlash in Germany, the rise of Hitler, and then World War II. Fulbright was loath to make that mistake again. He rarely saw conflicts in black and white, tried to avoid demonizing adversaries, and always looked for negotiated solutions first, preferably in a multilateral context. By contrast, Rusk was at Oxford in the early thirties, when the Nazis came to power. Later, he followed the hopeless attempts of Prime Minister Neville Chamberlain of Great Britain to negotiate with Hitler, an approach given one of history’s most stinging rebukes: appeasement. Rusk equated Communist totalitarianism with Nazi totalitarianism, and despised it as much. The movement of the Soviet Union to control and communize Central and Eastern Europe after World War II convinced him communism was a disease that infected nations with a hostility to personal freedom and an unquenchable aggressiveness. And he was determined not to be an appeaser. Thus, he and Fulbright came to Vietnam from different sides of an unbridgeable intellectual and emotional divide, formed decades before Vietnam appeared on America’s radar screen.
The psychological divide was reinforced on the pro-war side by the natural tendency in wartime to demonize one’s adversary and by the determination Johnson, Rusk, and others had not to “lose”
