CBS News Poll: U.S. involvement in Vietnam
As the 50th anniversary of the Tet Offensive approaches, few Americans today think the U.S. did the right thing in getting involved in the fighting in Vietnam. By a margin of more than two-to-one (51% to 22%), Americans think the U.S. should have stayed out of the conflict, versus those who believed the "did the right thing" by participating in the war. Roughly a quarter of respondents (27%) had no opinion.
With the passage of time, the percentage of Americans who think the U.S. did the right thing in Vietnam is relatively the same as when CBS first asked the question back in 1985, while the percentage that says America should have stayed out of the fighting has dropped over time, while the percentage who don't have an opinion has climbed.

Polling by the Gallup Organization at the time indicates that before the Tet Offensive, most Americans were supportive of the war effort. By February 1968 Americans were divided, and by 1970 most thought that sending U.S. troops to fight in Vietnam was a mistake.

This poll was conducted by telephone January 10-14, 2018 among a random sample of 1,009 adults nationwide. Data collection was conducted on behalf of CBS News by SSRS of Glen Mills, Pa. Phone numbers were dialed from samples of both standard land-line and cell phones.
The poll employed a random digit dial methodology. For the landline sample, a respondent was randomly selected from all adults in the household. For the cell sample, interviews were conducted with the person who answered the phone.
Interviews were conducted in English and Spanish using live interviewers. The data have been weighted to reflect U.S. Census figures on demographic variables. The error due to sampling for results based on the entire sample could be plus or minus four percentage points. The error for subgroups may be higher and is available by request. The margin of error includes the effects of standard weighting procedures which enlarge sampling error slightly.
