US President Donald Trump’s public support has fallen sharply following his decision to conduct a military operation in Iran, according to a new opinion poll cited in a report published on July 24, 2026. The survey indicates that his popularity over handling the Iran conflict has dropped close to its lowest level in history.

A Washington Post poll put Trump’s net approval rating for handling the Iran conflict at minus 40. CNN chief data analyst Harry Enten described the result as “historically very unpopular,” according to the report.

The poll also found that support for the military operation has declined steadily since the conflict began. Current backing for the operation is among the lowest levels recorded for modern US military interventions. Analysts said the findings indicate growing opposition among the US public to the Trump administration’s military actions on the Iran issue.
