Most Americans doubt Iran war succeeded, want conflict to end

Americans are signaling fatigue with the Iran war, but not confidence that the fighting produced a durable win. Across several new polls, the public says it wants the conflict to end, suspects Iran’s nuclear program was not permanently stopped and doubts that the United States came away with the better of any deal.

CBS News polling finds a stark split between the desire to stop the war and the belief that its costs were justified. Most Americans think Iran’s nuclear program has not been permanently halted, a majority believe Tehran will still threaten its neighbors, and relatively few say Washington is getting the better of the agreement. The poll also shows strain inside President Donald Trump’s Republican base, where about four in 10 Republicans say the conflict should continue until Iran gives up more.

Other surveys point in the same direction. AP-NORC finds about 59% of Americans say U.S. military action against Iran went too far, even as about two-thirds say preventing Iran from obtaining a nuclear weapon should be an extremely or very important foreign policy goal. That combination suggests Americans still support the objective in the abstract, while questioning the scale and consequences of the military response.

The skepticism is broader than a single poll. A University of Maryland Critical Issues Poll fielded by Ipsos from May 15 to 21 found 56% of Americans said the war had affected U.S. interests more negatively than positively. That view was overwhelming among Democrats, at 84%, but it also reached 63% of independents and 33% of Republicans.

A Chicago Council on Global Affairs-Ipsos survey taken May 1 to 3 found Americans saw the war as damaging to the cost of living, international relations, the country’s reputation abroad and national security. Just 18% were confident Iran would comply with a sanctions-relief deal tied to limits on its nuclear program, while 48% were confident the United States would comply. Forty-five percent described the conflict as a stalemate.

That sense of exhaustion is reinforced by Economist/YouGov polling published June 9, which found 68% wanted a deal to end the war as quickly as possible. At the same time, 92% expected the war to last more than a month longer, and 42% said it would continue for a year or more.

Analysts at Brookings say the public opposition is unusually persistent, while the Stimson Center argues Iran’s nuclear program has not been dismantled, its leverage over the Strait of Hormuz has grown and its missile arsenal remains largely intact. For policymakers, the warning is clear: Americans may want the war to end, but they are not yet persuaded the costs bought a lasting strategic gain.
