A recent Fox News poll indicates that a majority of voters are skeptical about whether a peace agreement with the U.S. will prevent Iran from developing nuclear weapons. Sixty-four percent of respondents believe it is unlikely that such an agreement will stop Iran's nuclear ambitions, a sentiment shared by 53% of Republicans, 69% of independents, and 73% of Democrats. This level of skepticism mirrors opinions from 2015 when a similar deal was proposed under the Obama administration.
The survey, conducted before the Trump administration announced a memorandum of understanding with Iran, which includes a reopening of the Strait of Hormuz and a 60-day ceasefire, shows that 58% of voters think the U.S. made the wrong choice in taking military action against Iran in February, while 41% support that decision. Among those who believe military action was justified, 50% think a peace deal will be effective, compared to only 25% of those who oppose it.
Seventy-six percent of voters consider it important to end Iran’s nuclear program, and 87% emphasize the importance of avoiding a long-term conflict. Concerns about the potential for a prolonged U.S. military commitment in Iran are prevalent, with 70% expressing significant worry.
In terms of President Trump's handling of Iran, 64% of voters disapprove, with 70% of Republicans approving, while 78% of independents and 92% of Democrats disapprove. Republican pollster Daron Shaw noted that voter attitudes on foreign policy are influenced by partisan perspectives, suggesting that support for engagement may decline over time.
The poll also reveals that voters support continued U.S. financial aid to Ukraine in its conflict with Russia, with 59% in favor, although fewer believe the war significantly impacts life in the U.S. Currently, voters are divided on who is winning the war, with 48% believing Ukraine is winning and 48% believing Russia is.
In the Middle East, a slight majority of voters (54%) express support for Israel over Palestine (42%), although this support has decreased from previous years. Additionally, 77% of voters view developments in the Middle East as relevant to life in the U.S.
The survey was conducted from June 12-15, 2026, with a sample of 1,002 registered voters and a margin of error of ±3 percentage points.
