According to a recent Fox News poll, voters express skepticism about whether a peace agreement would prevent Iran from developing nuclear weapons. Sixty-four percent—including over half of Republicans (53%), 69% of independents, and 73% of Democrats—believe a U.S. peace deal is unlikely to stop Iran’s nuclear ambitions. This perspective aligns closely with feelings from 2015 when, during the Obama administration’s negotiations, 63% of voters were similarly doubtful.
The bulk of the investigation was wrapped up before the Trump administration revealed a new memorandum of understanding with Iran, which included plans to reopen the Strait of Hormuz and a cease-fire for 60 days.
At the same time, 58% of respondents think the U.S. made a mistake by taking military action against Iran in February. Conversely, 41% see it as the right call. Notably, a larger portion of Democrats (84%) view it negatively compared to Republicans (75%) who approve.
When examining voters’ beliefs about the potential for a peace deal to succeed, those who approved of military action are significantly more optimistic—50% believe it could work, compared to just 25% of those who disagreed with that action.
A strong 76% of voters consider it important to halt Iran’s nuclear program, and 87% prioritize avoiding long-term conflict. Compared to earlier this year, these figures have both risen by 7 percentage points. Nearly 90% of Democrats, Republicans, and independents agree on the importance of preventing prolonged military involvement.
There are shared concerns regarding the potential escalation of tensions with Iran, as 70% of voters express significant worries. This includes majorities of Democrats (82%), independents (74%), and over half of Republicans (56%).
As for President Trump’s handling of Iran, 64% of voters disapprove, a figure consistent since March. Among Republicans, approval stands at 70%, while independents (78%) and Democrats (92%) predominantly disapprove.
Daron Shaw, a Republican pollster involved with the Fox News poll, acknowledges that voters’ foreign policy perspectives are often influenced by partisan leaders. He notes that support for engagement tends to wane over time as resources are committed, putting pressure on the president to resolve the situation in Iran before party cohesion erodes.
Voters outside of Iran continue to endorse U.S. financial assistance to Ukraine in its conflict against Russia, though fewer view the war as vital to American interests. Overall, 59% support continued aid to Ukraine, consistent over the last couple of years. However, belief that the conflict will influence domestic affairs has decreased to 67%, down from 85% at the start of the war.
Democrats (75%) are more likely than Republicans (62%) to regard Ukraine as important to the U.S., and support for ongoing aid to Ukraine also skews Democratic, with 72% favoring it compared to 50% of Republicans.
Opinions are divided regarding who is winning the conflict, with 48% siding with Ukraine and another 48% with Russia. Among party lines, 56% of Democrats believe Ukraine will prevail, while more Republicans (53%) and independents (55%) lean towards thinking Russia is in a better position.
In the Middle East, support for Israelis over Palestinians stands at 54% compared to 42% for Palestinians. This backing has remained stable since 2025 but has declined from a peak of 68% in late 2023. Currently, 77% of Republicans favor Israel, whereas 62% of Democrats lean towards the Palestinians, with secessionists divided (48% Israelis, 45% Palestinians).
Despite varying opinions, many voters still hold that events in the Middle East are pertinent to life in the U.S. About 77% believe developments there are significant, although this is down from 81% a year prior.
The survey showed mixed feelings about employing military force against suspected drug traffickers—52% support it while 48% are against it. However, there’s a significant opposition against utilizing the military to instigate regime change in Cuba, with only 35% in favor and 64% against.
