Trends in Popular Support for the Wars in Korea and Vietnam 1

In an examination of responses to public opinion poll questions designed to assess the degree of generalized support for the wars in Korea and Vietnam, popular support for the two wars was found to follow highly similar patterns. Support was high initially but declined as a logarithmic function of American casualties, a function remarkably similar for both wars. While support for the war in Vietnam did finally drop below those levels found during the Korean War, it did so only after the fighting had gone on considerably longer and only after American casualties had greatly surpassed those of the earlier war. These trends seem to have been fairly impervious to particular events in either of the wars. It is suggested that the greater vocal opposition to the Vietnam War reflects mainly a shift of opinion within the intellectual left on the wisdom of the two wars. Armed with new techniques of protest learned in its identification with the civil rights movement, the intellectual left has been able effectively to garner great attention for its cause during the Vietnamese War. Also noted was the presence of a rather large body of opinion inclined to follow the President on war policy, giving him considerable room for maneuver, at least in the short run, and making public opinion in this area highly sensitive to current policy. A crude comparison with data from World War II suggests that, while the earlier war was unquestionably more "popular" than the wars in Korea and Vietnam, support was less consensual than might be expected. The popularity of the Korean War rose slowly after its conclusion, but this sort of retrospective support for World Wars I and II may have declined as time went by and, at any rate, was quite sensitive to current events, In repeated instances, differences in question wording were found to alter substantially the response generated to poll questions about the wars.
