Public Disapproval Marks U.S.-Iran Conflict Under Trump

The conflict between the U.S. and Iran under President Donald Trump has been marked by public disapproval. This differs from past American wars. In Afghanistan and Iraq, public support began strong and dwindled over time. In contrast, support for military action against Iran was low from the start and remained steady.

A Gallup poll conducted from June 1 to June 15, roughly three months into the conflict, indicated that only 34% of Americans approved of the military action against Iran. At a similar stage during the 2011 Libya campaign, 39% approved, and 60% supported the Iraq war at 260 days in. The stark difference in public sentiment is evident when compared to the initial 90% approval for Afghanistan and 76% for Iraq.

A Quinnipiac poll from March 2026 showed that 40% of registered voters supported the Iran action, while 53% opposed it. The New York Times found that initial support, as registered by a CNN poll, was the lowest for any American military action. Gallup’s review of several military engagements since the 1980s revealed only two, before Iran, lacked majority support initially: Libya (47%) and Syria (50%).

Disapproval of the Iran war has since grown. A Washington Post-Ipsos poll in mid-July found just 29% approved of Trump’s handling of the war, with 68% believing the conflict was not worth it. This mirrors the 2013 sentiment for Afghanistan.

Absence of Wartime Approval Boost

A common phenomenon in past conflicts, where presidential approval ratings surged, has been absent for Trump. George W. Bush saw approval spikes after the onset of both the Afghanistan and Iraq wars. In contrast, Trump’s approval rating was 40% at February’s end-caps before dropping further in March.

Mark Jones from Rice University and Karl Rove have noted this absence of a rally-round-the-flag effect. Polling before and after the initial strikes showed no change in Trump’s overall or foreign policy ratings. Similarly, Obama’s approval didn’t spike from the Libya intervention, only momentarily after the killing of Osama bin Laden.

Factors Behind the War’s Unpopularity

Experts attribute several factors to the Iran war’s low support. Primarily, it was a war of choice without a domestic trigger. Rising gasoline prices affected public sentiment as conflict continued, with Reuters/Ipsos reporting only 25% of citizens approved of Trump’s handling of living costs.

Political polarization further eroded support. Gallup recorded 79% approval among Republicans, contrasting with only 26% from independents and 8% from Democrats. Pollster Scott Rasmussen linked the negative response to this polarization. Rapid opinion shifts compared to other Trump-era activities were observed by Nate Silver and others.

Comparisons with Past Wars

Unlike Vietnam or Iraq, the Iran conflict has not dominated public attention. While Vietnam and Iraq were the country’s top concerns at their peaks, the current issues center more on the cost of living. Further, the Iran conflict has resulted in fewer American casualties compared to past wars, like Afghanistan’s 2,500 over two decades. Currently, 18 U.S. service members have died in the ongoing Iran conflict.

The Pentagon’s figures have fluctuated; Defense Secretary Pete Hegseth claimed continued public backing before the Senate Armed Services Committee. However, real-time figures and poll data suggest otherwise.

Future Outlook

With no immediate resolution in sight, the conflict’s next phases depend on diplomatic maneuvers and military strategies. As the military campaign continues, any shift in operations or diplomatic efforts with Iran might alter the conflict’s trajectory. Observers are closely watching for changes.
