However, the most cruel mistake occurred with the failure to understand the Vietnam war. Some people sincerely wanted all wars to stop just as soon as possible; others believed that there should be room for national, or communist, self-determination in Vietnam, or in Cambodia, as we see today with particular clarity. But members of the U.S. anti-war movement wound up being involved in the betrayal of Far Eastern nations, in a genocide and in the suffering today imposed on 30 million people there. Do those convinced pacifists hear the moans coming from there? Do they understand their responsibility today? Or do they prefer not to hear?
