Iran crisis update: Only about one in three Americans now support the U.S. war with Iran, according to a new Reuters/Ipsos poll, giving President Donald Trump a domestic political problem just as his administration says it is trying to keep a pause in strikes alive.

The poll, conducted Friday through Sunday, found that support for the conflict has fallen to its lowest Reuters/Ipsos reading since the early days of the five-month war. It also found that 69% of Americans, including four in 10 Republicans, believe Trump has not clearly explained the goals of U.S. military involvement in Iran.

The poll lands during a strike pause

Reuters, in reporting carried by Al-Monitor and Internazionale, said approval of the Iran war has stayed below 40% since the United States and Israel launched strikes on February 28. The latest survey gathered responses from 1,246 U.S. adults and had a margin of error of 3 percentage points.

The timing is awkward for the White House. Washington abruptly suspended a two-week air campaign against Iran over the weekend, and Trump said Monday the United States was having “good talks” with Tehran. He also warned that if diplomacy fails, U.S. strikes could resume.

CBC News, carrying Thomson Reuters reporting, said public disapproval of the war is weighing on Trump and Republicans ahead of November’s midterm elections, when the party will be defending slim congressional majorities.

Most say the goals are unclear

The central finding is not just that support is low. It is that most Americans say they do not understand what the president is trying to achieve.

Reuters reported that Trump has described the conflict in shifting terms, including preventing Iran from obtaining a nuclear weapon, degrading its ballistic missile capability, and supporting Iranians who want to topple their leaders. The poll found that most respondents still do not think those goals have been clearly explained.

A White House spokeswoman told Reuters that Trump would not make decisions based on “fluid opinion polls” and said the president remains focused on preventing Iran from acquiring a nuclear weapon.

War costs are hitting voters

The poll also adds a domestic dimension to the current Iran crisis. Reuters reported that gasoline prices are averaging just over $4 a gallon nationwide, up from about $3 before the conflict began on February 28. That price pressure makes the war harder to separate from the economic concerns voters already had before the latest military escalation.

The survey found Trump’s overall approval rating at 37%, up three points from last month, but the Iran war remains a weak spot. Independent registered voters in the poll favored the Democratic congressional candidate over the Republican by 36% to 20%, Reuters reported.

That does not mean the military pause will hold, or that public opinion will drive U.S. strategy. But it gives the White House less room for a prolonged conflict if talks collapse and airstrikes resume.

Why it matters

The newest angle in the Iran crisis is domestic pressure. Trump is trying to sell diplomacy while keeping the threat of renewed military action on the table, but the latest polling shows Americans are skeptical of the war’s purpose and wary of its cost.

That political backdrop could matter if the U.S.-Iran pause breaks, if Congress tries again to constrain the war, or if oil and gasoline prices climb during the final stretch before the midterms.
