Mr. Vaughn--who in his best-known TV role, Napoleon Solo on The Man from UNCLE, hunted bad guys on behalf of the United Nations--was on record as saying that "the war in Vietnam cannot be rationalized by moral man." His reasons go back to the Geneva accord of 1954 and the ways in which the United States abetted Ngo Dinh Diem in avoiding elections in 1956. RV: "I don't believe that we can stop the spread of Communism by sacrificing the principles of democracy." An often heated discussion that helps us focus on the whole background to the late-Sixties divisions.
