Public Support for Trump-led War Against Iran Plummet

Public support for the war against Iran, launched by Donald Trump in late February 2026, has declined more rapidly than support for previous U.S. conflicts in Iraq, Afghanistan, and Vietnam. A Washington Post-Ipsos poll shows 68% of Americans believe the war is not worth fighting, while a Post-ABC poll found 61% viewed the conflict as a mistake within two months of its start.

Despite the high disapproval rating, the conflict has not become a top priority for the American public. Only single-digit percentages of respondents cite foreign wars as the country's most important problem. This low salience is largely attributed to the absence of U.S. ground troops, though recent reports indicate the first American troop deaths in several months.

While the war may not directly influence the November midterm elections, it is impacting the domestic economy by increasing gasoline prices.
