A new CBS News/YouGov poll reveals that 78% of Americans believe the U.S. should end the conflict with Iran immediately, while 79% doubt the peace agreement will bring pro-U.S. leadership to Tehran. The survey, conducted June 17-19, 2026, also found that 66% of Americans think the war has had a greater economic impact than the Trump administration anticipated.
Key Developments
- 78% of Americans support ending the Iran war now, per CBS News/YouGov.
- 79% doubt the peace deal will install pro-U.S. leadership in Iran.
- 66% believe the conflict’s economic fallout was underestimated.
Trump’s Peace Deal
President Donald Trump signed a memorandum of understanding (MOU) with Iran last week, with Vice President JD Vance and envoys Jared Kushner and Steve Witkoff negotiating a permanent ceasefire in Switzerland. The agreement includes a 60-day truce to finalize details.
Public Skepticism
Only 22% of respondents believe the deal benefits the U.S. more than Iran. Two-thirds think the administration sought an end to the conflict rather than achieving all U.S. goals. The poll also shows 60% of Republicans and 56% of MAGA Republicans support ending the war now.
Economic and Military Costs
The war’s financial toll includes $40 billion in Pentagon spending, with $80 billion requested for supplemental funding. The conflict has depleted key missile inventories, including 1,000 Tomahawk missiles at $2.5 million each. The Pentagon invoked the Defense Production Act to replenish supplies.
Strategic Concerns
Experts and officials question whether the deal has permanently halted Iran’s nuclear program or ended regional threats. 13 U.S. service members and 7,500 civilians have died in the conflict. The agreement’s long-term impact remains uncertain.
