A new public opinion survey by YouGov and The Economist suggests that 57 percent of Americans believe the decision to launch the war on Iran was wrong, while only 27 percent say it was the right decision.
Some 46 percent of Americans also believe the war will last another year or more, the poll suggested.
The share of respondents who say the war will end within a month, or is already over, has fallen to 8 percent from 20 percent in March, the poll showed.
