US public support for Iran war falls as Trump approval at record low: Poll

What the report says

A Reuters/Ipsos poll published by Al Jazeera on August 24, 2026, found that support in the United States for the war on Iran has declined to its lowest point since the early phase of the conflict. According to the survey, 31 percent of Americans said they backed US military action against Iran, down from 37 percent in March and 34 percent earlier this month. The drop was especially visible among Republicans, whose support fell to 69 percent from 77 percent in March.

The poll also suggested that President Donald Trump remains under pressure from the war politically. Just 33 percent of respondents said they approved of his performance as president, matching the lowest level recorded in the Reuters/Ipsos polling series across both of his terms. Al Jazeera reported that Trump has argued the campaign is needed to stop Iran from developing a nuclear weapon.

The article said economic concerns are also shaping public opinion. Rising fuel prices, linked in the report to disruptions in oil exports from the region, have increased the cost of gasoline in the United States and may complicate Republican prospects ahead of the 2026 midterm elections. A large majority of respondents, 83 percent, said they expect the conflict to last a long time.

The poll surveyed 1,215 US adults over four days and had a margin of error of 3 percentage points. As general background, polling trends like this can matter because war support, inflation concerns and presidential approval often influence voter attitudes before congressional elections.
