Wartime often bolsters the political standing of incumbents, and President Donald Trump appears to be benefiting from that dynamic. While future foreign conflicts remain broadly unpopular, American voters have shown strong support for Trump’s stance that Iran must be stopped from acquiring a nuclear weapon at any cost.
Insider Advantage conducted a survey asking voters whether they believe President Trump should take “all necessary” steps to stop Iran’s military nuclear program. The results showed that an overwhelming 74.4% of respondents agreed, while 22.9% disagreed. Additionally, 2.7% were undecided or had no opinion.
The poll comes amid a broader trend revealing just how war-weary the American public has become more than two decades after former President George W. Bush launched the War on Terror, leading the U.S. into prolonged conflicts in Afghanistan and Iraq. Today, Americans oppose going to war with Iran by a 20-point margin—45% against, 25% in favor—while 30% remain unsure, according to a Washington Post survey.
However, self-identified MAGA voters are firmly behind Trump should he decide to authorize the first U.S. airstrike. According to J.L. Partners, which shared data with the New York Post, 65% of Trump supporters would back U.S. strikes on Iranian positions, while only 19% would oppose such action.
Republicans who identify as “traditional” are even more supportive of military action, with 51% in favor of striking Iran and 28% opposed. Overall, Republicans back a U.S. strike by a margin of 58% to 25%, while 17% remain undecided or neutral, according to the New York Post.
“This poll makes clear: the Republican base is not isolationist. They back forceful U.S. and Israeli action to stop Iran, and see Israel’s fight as America’s fight,” James Johnson, co-founder of the New York-based J.L. Partners, assessed in a statement. Among all voters, Trump maintains a positive approval rating on his handling of the Iran conflict, with 46% expressing support compared to 40% who disapprove.
While Trump is constitutionally barred from seeking a third term, he remains highly attuned to any signs of waning support over his foreign policy decisions. So far, that support appears solid: 95% of voters who backed him in 2024 say they continue to stand by him.
