What Americans Told Pollsters About the Iran War

When a country goes to war, pollsters ask the same question in a dozen slightly different ways, and the answers form a mosaic. This is what the major surveys of American opinion on the 2026 conflict with Iran showed, with the pollster and the date attached to every number.

• A Quinnipiac poll conducted the weekend before March 10, 2026 found 53 percent of registered voters opposed U.S. military action against Iran and 40 percent supported it ^[1].
• A Fox News poll reported by PBS showed an even 50-50 split on the action ^[1].
• Gallup’s June 1-15, 2026 survey found 34 percent approved of the military action, its lowest approval for a U.S. military operation since the 1980s, below levels for the Gulf War and Afghanistan ^[2].
• Roughly half of voters in Quinnipiac and Fox polls said the action made the U.S. less safe ^[1].

The early reading: divided, with a lean toward opposition

PBS NewsHour’s review of early polling found a Quinnipiac survey, conducted the weekend before March 10, 2026, in which 53 percent of registered voters opposed U.S. military action against Iran, 40 percent supported it, and about 10 percent were uncertain. A Fox News poll, in contrast, produced an even 50-50 split between approval and disapproval. Snap polls from The Washington Post and CNN, taken shortly after the strikes began, found more Americans rejecting the action than embracing it ^[1].

Republicans, PBS noted, largely supported the president, though they expressed wariness about ground deployments ^[1].

Safety and threat

On whether the action made the country safer, about half of voters in the Quinnipiac and Fox polls said it made the U.S. less safe, while roughly 30 percent said it enhanced safety. In CNN’s poll, about half of adults said the strikes would make Iran more of a threat, versus about 30 percent who thought the danger would decrease ^[1].

The summer reading: lower approval

By June, Gallup found that 34 percent of Americans approved of the military action, a comparison it drew with earlier operations; the Iran figure was below levels recorded for the Gulf War and the war in Afghanistan, and in the same range as Libya in 2011 (39 percent) and Haiti in 1994 (36 percent) in follow-up polling ^[2]. The poll was conducted June 1 to 15, 2026 ^[2].

Trust, threat and prices

The polls also asked about the threat itself and about trust. In Quinnipiac’s survey about 55 percent believed Iran did not pose an imminent military threat before the strikes, while about 60 percent in the Fox News poll said Iran poses a real national security threat; AP-NORC found about half of adults highly concerned that Iran’s nuclear program was a direct threat ^[1]. Only about 30 percent in each of the Quinnipiac and Fox polls said the action made the country safer, against about half who said less safe ^[1].

Trust in the decision-maker was low: a CNN poll found about 6 in 10 adults trusted President Trump “not much” or “not at all” on military force decisions, and an AP-NORC poll taken before the strikes had 56 percent trusting him only a little or not at all ^[1]. Prices were a separate worry, with roughly 70 percent very or somewhat concerned about oil and gasoline increases, including about half of Republicans ^[1]. Quick text-message snap polls from the Washington Post and CNN also showed more Americans rejecting the action than embracing it ^[1]. These are different questions asked of different samples, so they describe a mood more than a single measurement.

How to hold these numbers

These surveys differ in sample (registered voters versus all adults), timing (March snap polls versus June) and question (support versus approve versus safety). That is why they do not line up neatly. What does line up is the broad shape: no poll here shows a majority of Americans enthusiastically behind the operation, and the one with the longest view, Gallup’s, shows approval in the mid-thirties ^[1][2].
