A majority of Americans expect the U.S. conflict with Iran to grind on for months or years, and more than three-quarters say the fighting has proved harder than President Donald Trump anticipated, according to a new CBS News/YouGov survey released Sunday.

The poll lands as the fighting escalates again and gas prices weigh on households, and it captures a public that is frustrated, uncertain, and increasingly skeptical that the White House is leveling with them about the Strait of Hormuz.

Asked how much longer the war will last, 1% of adults said days and 8% said weeks, according to the CBS toplines.

Another 37% said months, 21% said years, and 33% were unsure.

Combined, 58% see no quick exit, a striking gap from Trump's early prediction that the campaign would be short.

Seventy-six percent said the conflict has turned out harder than the administration expected.

The public also wants out.

Sixty-seven percent said the U.S. should end the war now, while 33% said Washington should press on until Iran makes further concessions.

That preference has held as the majority view for months, though the share calling for an immediate end has narrowed since June, when Trump announced a memorandum of understanding for a ceasefire that later collapsed.

Republicans, who had largely backed the president on ending the fight last month, now say the war should continue.

Trump's handling of Iran drew 35% approval in the poll, below his overall job approval of 39%.

Sixty percent said the president makes the situation sound better than it really is, a finding that tracks with the poll's broader theme of uncertainty: 58% said they felt "uncertain," and 57% said they felt "frustrated" about the conflict.

Americans still tell CBS the U.S. has important objectives worth pursuing, including reopening the Strait of Hormuz, halting Iran's nuclear program, and blunting Tehran's threat to the region.

But they doubt the path will be easy.

Perceptions of how the war is going have ticked down over the course of the fighting, and views on who holds the advantage remain mixed, with 40% saying the U.S., 22% saying Iran and 38% saying neither side.

The domestic backdrop is dragging on the president's numbers.

Seventy-five percent said their incomes are not keeping up with inflation, and half described gas prices as difficult or a hardship.

Those hit hardest at the pump are the most likely to disapprove of the military campaign, according to the survey, tying kitchen-table pressure directly to views of the war.

The CBS/YouGov poll surveyed 2,193 U.S. adults July 22-24, weighted by gender, age, race, education, and 2024 presidential vote, with an overall margin of sampling error of plus or minus 2.7 percentage points; subgroup margins are larger.

On which party has the better approach to Iran, 32% picked Trump and Republicans, 30% picked Democrats, 22% picked neither, and 15% were unsure, resulting in a statistical tie that leaves the political opening from public frustration unclaimed as the conflict enters its next phase.
