Poll: Majority Say Trump Administration Fails To Explain U.S. War Aims Against Iran

A Washington Post poll conducted March 12, 2026 finds U.S. public opinion divided over the U.S. military campaign against Iran: 42% of respondents say they support the campaign, 40% oppose it, and 17% are unsure.

This is a modest shift from an earlier Post poll that recorded 39% support and 52% opposition when questions referenced "President Trump ordering airstrikes against Iran."

Pollsters note that offering an "unsure" option has captured between 7% and 30% of respondents, indicating opinions remain in flux less than two weeks into the military operation.

The poll shows a discernible rise in appetite for continuing strikes: the share saying the United States should "continue military strikes against Iran" increased from 25% in the first weekend of attacks to 34% in the latest survey.

Those saying the U.S. should "stop strikes at this time" fell from 47% to 42%.

Among supporters of the overall campaign, 72% want strikes to continue, and support rose notably among Republicans, independents, women and people aged 65 and older.

A clear majority of respondents judge the Trump administration has not clearly explained the goals of U.S. military action: just over one-third (35%) say the goals have been clearly explained while 65% say they have not.

Poll authors note this proportion "has hardly shifted since the second day of the war."

More than six in 10 Americans call the number of U.S. military casualties so far "unacceptable," with the Pentagon reporting seven U.S. service members killed and roughly 140 wounded.

Respondents are skeptical that the military campaign will enhance long-term U.S. security: by 53% to 46% more Americans say U.S. military actions in Iran will not contribute to long-term U.S. security.

When asked why the strikes might improve security, those who said they would cited Iran as a threat (19%), preventing a nuclear threat (15%), demonstrating military strength (9%) and reducing terrorism (8%).

A subset of respondents argued the strikes could backfire and harm U.S. security.
