A large majority of American voters support President Donald Trump’s stance on preventing Iran from developing nuclear weapons, even as broader national sentiment reflects strong opposition to entering another foreign conflict.
According to a new Insider Advantage poll, 74.4% of respondents agreed that Trump should take “all necessary” steps to stop Iran’s military nuclear program. Only 22.9% disagreed, while 2.7% remained undecided.
The poll results reflect continued voter backing for Trump’s foreign policy posture amid rising tensions in the Middle East.

The findings come at a time when national polling shows deep fatigue with foreign wars.
A Washington Post survey found that Americans oppose going to war with Iran by a 20-point margin—45% against versus 25% in favor—with 30% undecided.
Support for military action is particularly strong among Trump’s political base.
A J.L. Partners survey conducted for the New York Post found that 65% of voters who supported Trump in the 2024 election would back U.S. airstrikes on Iranian outposts, while just 19% would oppose such a move.

Republican voters identifying as “traditional” also support military action, with 51% in favor and 28% opposed.
Among all Republicans, support for striking Iran stands at 58%, with 25% against and 17% undecided.
“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,” J.L. Partners co-founder James Johnson said in a statement.
Among the general electorate, President Trump’s handling of the Iran situation holds a net-positive rating.
According to the same J.L. Partners data, 46% of all voters approve of his actions so far, compared to 40% who disapprove.
Although President Trump is ineligible to run for a third term, his administration remains attentive to internal dynamics within the Republican Party and among MAGA-aligned figures.
A separate poll showed that 95% of those who voted for Trump in 2024 continue to support him, despite differing views on military engagement.
Divisions within the Republican Party have surfaced in recent weeks over the president’s posture toward Iran.
Prominent America First figures such as Congresswoman Marjorie Taylor Greene (R-GA) and media host Tucker Carlson have urged Trump to avoid direct military involvement.
Conversely, other conservatives, including Senator Ted Cruz (R-TX) and commentator Mark Levin, have advocated for a stronger military response.
According to sources familiar with recent internal outreach efforts, the White House has sought to ease tensions by opening direct lines of communication with key MAGA personalities.
President Trump and senior aides have spoken with top influencers to discourage public criticism and foster unity within the movement.
Carlson, after publishing a newsletter that referred to the president as “complicit” in last week’s military developments involving Israel, reportedly contacted Trump to apologize.
To be clear: This is Trump’s GOP. It’s not Tucker Carlson’s or Tulsi Gabbard’s.
Trump (88% favorable) is far more popular than either one with the GOP.

Steve Bannon, another high-profile MAGA voice, stated during his podcast on Wednesday that supporters would ultimately stand behind Trump regardless of his decisions regarding military engagement.
The effort to consolidate support appears to be working, at least for now.
While debates over foreign intervention continue within Republican circles, polling suggests that Trump retains solid backing from both his base and a broader swath of the American electorate on the question of how to handle Iran’s nuclear ambitions.
