7 in 10 Americans Say Iran War Not Worth Fighting

Chicago Council on Global Affairs | Dina Smeltz and Lama El Baz

The 2026 Chicago Council Survey revealed that 68 percent of Americans view the ongoing US-Israeli war with Iran as not worth the costs, contrasting with 63 percent of Republicans who still support the military campaign. CSIS estimated the conflict's financial cost at $34 billion to $42 billion, alongside 18 US service personnel killed and 624 wounded since February 28, 2026.

This domestic discontent reflects persistent threat perceptions, as 49 percent of respondents still consider Iran’s nuclear program a critical threat—a figure unchanged from 2023 despite Operation Midnight Hammer airstrikes. While 70 percent of Americans support permitting Iranian global petroleum exports and 58 percent back stopping Israeli operations in Lebanon under a prospective peace deal, sharp boundaries remain. Majorities firmly reject core concessions desired by Tehran, including continued Iranian ballistic missile development (80 percent), retention of enriched uranium stockpiles (74 percent), and control over the Strait of Hormuz (68 percent), creating significant domestic constraints on negotiations.

Comment

The operational execution of Operation Midnight Hammer demonstrated that degrading hardened nuclear infrastructure through air power alone creates a persistent strategic friction between tactical counter-proliferation goals and long-term conflict termination. Relying on stand-off strikes without securing verifiable access to enriched uranium stockpiles forces political leadership into a prolonged attritional posture. This asymmetry leaves Washington with narrow diplomatic leverage when public risk tolerance declines during sustained maritime interdictions in chokepoints like the Strait of Hormuz.

Strategic Question for Discussion

Which carries more weight when negotiating conflict termination after Operation Midnight Hammer—the physical destruction of hardened nuclear facilities or the political constraints imposed by declining domestic tolerance for prolonged interdiction in the Strait of Hormuz?
