A War Without a Mandate: How Operation Epic Fury Launched With the Lowest Public Support of Any Modern U.S. Military Campaign

On the morning of February 28, 2026, the United States and Israel launched "Operation Epic Fury" — a sweeping military campaign against Iran targeting its leadership, military installations, and nuclear facilities. President Trump announced the strikes via a TruthSocial post at 2:00 AM EST [1]. Within hours, Iran's Supreme Leader Ayatollah Ali Khamenei was dead, along with several senior military and political figures. Iran vowed swift retaliation, and reports of missile attacks across the Middle East began flooding in [2].

But behind the dramatic military escalation lies a striking political reality: the American public never wanted this war. According to a convergence of polling data from multiple respected organizations, Operation Epic Fury was launched with the thinnest public support of any major U.S. military action in modern history — and the numbers have only gotten worse since the bombs started falling.

The 21% Figure: America Before the Strikes

The University of Maryland's Critical Issues Poll, conducted by SSRS from February 5-9, 2026, among 1,004 U.S. adults with a margin of error of 3.5 percentage points, found that just 21% of Americans favored the United States initiating an attack on Iran. Forty-nine percent opposed such action, and 30% said they didn't know [3].

The partisan breakdown was revealing but not surprising. Forty percent of Republicans favored an attack, compared to just 6% of Democrats and 21% of independents. Among those who opposed, 74% of Democrats, 51% of independents, and 25% of Republicans said they were against initiating military action. Notably, 35% of Republicans — more than a third of the president's own party — said they simply didn't know, a figure significantly higher than the 19% of Democrats who expressed uncertainty [3].

The poll also probed a deeper question: whose interests would a war with Iran actually serve? Americans were divided into rough thirds — 31% said it would most advance American interests, 35% said it would most benefit other parties, and 33% said they didn't know. Among those who identified other beneficiaries, 16% pointed to Israel, 11% to the Iranian people, and 3% to some Arab states [3].

After the Strikes: Disapproval Deepens

If the administration hoped that a "rally around the flag" effect would shift public opinion once the strikes began, the data tells a different story.

A Reuters/Ipsos poll conducted February 28 through March 1, among 1,282 adults, found that 43% of Americans disapproved of the military strikes while only 27% approved. Roughly three in ten said they were unsure [4]. Among Democrats, nearly three-quarters (74%) disapproved, compared with just 7% who approved. Even among Republicans, the 55% approval figure was far from the near-unanimous support presidents have historically enjoyed from their own party during the opening days of military action [4].

A CNN/SSRS poll conducted on February 28 and March 1 painted an even starker picture: 59% of Americans disapproved of the initial decision to strike Iran, with 41% approving. Strong disapproval (31%) roughly doubled strong approval (16%). Most critically, 56% of Americans said they see long-term military conflict between the U.S. and Iran as at least somewhat likely, with 24% calling it very likely. Sixty percent said they did not believe Trump had a clear plan for handling the situation, and 62% said he should get congressional approval for any further military action [5].

A YouGov snap poll fielded on February 28 found 34% of Americans approved of the attacks, with 44% disapproving and 22% unsure. The partisan polarization was extreme: Republicans approved 69-12, Democrats disapproved 70-10, and independents leaned heavily against the strikes — 52% disapproved versus just 20% who approved [6].

A separate CBS News/YouGov poll of 2,264 people released after the strikes showed a more even split, with 51% in favor and 49% opposed, though this survey specifically framed the question around military action to stop Iran from making nuclear weapons — a narrower framing that may account for the higher support [7].

Across all of these surveys, one consistent finding stood out: 56% of Americans said the president uses military force "too much," including 23% of Republicans, 87% of Democrats, and 60% of independents [4].

A Historic Departure

The numbers become even more striking when placed in historical context. Every modern American president who launched a major military campaign had the public behind them at the outset. The 1991 Gulf War had 76% approval. The 2001 Afghanistan invasion following the September 11 attacks reached 92%. Even the Iraq War in 2003, later widely considered a strategic blunder built on flawed intelligence about weapons of mass destruction, launched with 71% public approval — and 93% among Republicans [8].

Trump is the first president in modern history to launch major military strikes against a sovereign nation with more Americans opposed than in favor. The YouGov approval rating of 34% is less than half the support George W. Bush had when he invaded Iraq. Even the Republican support figure of 69% would have been considered a catastrophic failure of party unity in any previous wartime administration [8].

Diplomacy Abandoned

What makes the low public support especially significant is the diplomatic context. On February 26 — just two days before the strikes — Oman's Foreign Minister Badr Al Busaidi publicly declared that a "breakthrough" had been reached in U.S.-Iran nuclear talks. Iran had agreed to "zero stockpiling" of enriched uranium, meaning it would never accumulate the material needed to build a nuclear weapon. Existing stockpiles would be degraded to the lowest possible level and converted into irreversible fuel [9].

"If the ultimate objective is to ensure forever that Iran cannot have a nuclear bomb, I think we have cracked that problem through these negotiations," Al Busaidi told CBS News, adding that all remaining issues could be resolved "amicably and comprehensively" within a few months [10].

The CBS News pre-conflict poll, conducted February 25-27, captured the public's thinking in these final days of diplomacy. Americans voiced collective uncertainty about how long any conflict with Iran might last, with more believing it would stretch on for months or years rather than days or weeks. Those who expected a quick resolution tended to favor military action; those who anticipated a prolonged engagement opposed it [7].

Yet the administration moved forward with strikes just 48 hours after the reported diplomatic breakthrough, a decision that has drawn sharp criticism from across the political spectrum.

A Fractured Republican Party

Perhaps the most politically consequential finding across the polling data is the degree to which the Iran strikes have divided Republicans themselves.

The strikes were launched without congressional authorization, and the congressional response has exposed deep fissures within the GOP [11]. Senator Rand Paul and Representative Thomas Massie — both Kentucky Republicans and long-time skeptics of military intervention — expressed frustration that Trump had bypassed Congress. Representative Warren Davidson of Ohio signaled he would support a Democratic-led bill requiring Trump to make his case to Congress, stating plainly: "War requires Congressional authorization" [11].

Even lawmakers who back the strikes in principle have pushed back on the process. Republican Representative Don Bacon of Nebraska said he would vote against the immediate war powers resolution but insisted that Trump must seek congressional authorization for "extended operations," noting that prolonged military engagement legally requires coming to Congress [12].

Outside Congress, the fractures run even deeper. High-profile figures within Trump's own MAGA movement — including former Representative Marjorie Taylor Greene and commentator Tucker Carlson — publicly opposed an Iran attack [12]. Both the House and Senate had already drafted war powers resolutions before the strikes began, and they are now barreling toward a rare war powers vote that will serve as a referendum on the president's decision to act unilaterally [11].

The Threat Perception Gap

The polling reveals another significant disconnect: most Americans do not believe the strikes will make them safer. According to the Reuters/Ipsos survey, 54% of respondents said Iran would become more of a threat to the United States as a result of the military action, while only 28% said the strikes would make Iran less of a threat [4]. Americans are split on whether Trump's willingness to use force strengthens or weakens the country's position in the world, with 48% on each side [4].

The CNN poll reinforced this anxiety, with a majority saying they lacked trust in Trump to make the right decisions about the use of force in Iran [5]. The combination of low approval, high expectation of prolonged conflict, and majority distrust in presidential decision-making represents an unusually bleak assessment for a military operation in its opening days.

What the Numbers Mean

The convergence of multiple polls from different organizations — University of Maryland, Reuters/Ipsos, CNN/SSRS, YouGov, CBS News/YouGov — paints a consistent picture. The exact percentages vary depending on timing, methodology, and question framing, but the overall pattern is unmistakable: a majority of Americans either opposed or were uncertain about military action against Iran before the strikes, and disapproval has deepened since.

The 21% figure from the University of Maryland poll represents the pre-strike baseline — what Americans thought about initiating an attack when diplomacy was still on the table. The post-strike numbers, ranging from 27% to 41% approval depending on the poll, reflect a modest rally effect that still leaves the administration well below majority support.

For the White House, the political calculus is precarious. Wars that begin without public support rarely gain it over time. The Iraq War's 71% initial approval eventually cratered, helping to sweep Democrats into Congress in 2006 and the White House in 2008. Operation Epic Fury begins from a far lower starting point, with a Congress already preparing to assert its war powers authority, a Republican Party visibly divided, and a public that — by every available measure — did not ask for this fight.

The question now is not whether Americans support the war. The polls have answered that. The question is what comes next — and whether the institutions designed to check executive military power will respond to what the public is clearly saying.
