Does Vietnam-era mentality continue in the USA?

If the following poll data says anything, the mindset opposed to seriously defeating the Iranian dictatorship continues in the USA:

A majority of Americans want the United States to end the war with Iran now, according to a recent CBS News/YouGov poll.

The survey, which was taken Wednesday through Friday, asked participants, “The Conflict with Iran: What Should the U.S. Do Now?” CBS reported Sunday.

Seventy-eight percent said the nation should end the conflict now, while 22 percent said continue the conflict until Iran gives up more:

The poll also surveyed Republicans, asking them, “What Should the U.S. Do Now?”

Sixty percent of all Republicans said the nation should end the conflict now and 56 percent of “MAGA” Republicans agreed. Forty percent of Republicans said the nation should continue the conflict until Iran gives up more, while 44 percent of “MAGA” Republicans agreed.

“This CBS News/YouGov survey was conducted with a nationally representative sample of 2,519 U.S. adults interviewed between June 17-19, 2026. The sample was weighted to be representative of adults nationwide according to gender, age, race, and education, based on the U.S. Census American Community Survey and Current Population Survey, as well as 2024 presidential vote. The margin of error is ±2.4 points,” the article noted.

Now this is coming from a MSM business, so for all we know, it could be faked and distorted. Even so, if there's anything to it, it'll just further make this a most discouraging situation, considering there appears to be a sad case of those in the USA who won't study reality seriously. There's already people in Israel who're understandably worried about the deal with Iran, and if it leaves the current dictatorship in place, that's what's bad.
