Sixty-one percent of Americans say President Donald Trump's war in Iran was a mistake, while 36% say it was the right decision, according to a new poll. Nearly all respondents who said the war was the right decision identified as Republicans.

The poll found that 91% of self-identified Democrats said the war was a mistake, while 71% of independents called it a mistake and 24% said it was the right decision. Among self-identified MAGA Republicans, 86% said the war was the right decision. Non-MAGA Republicans were divided, with 50% calling it the right decision and 49% calling it a mistake.

The poll also found that 61% of respondents believed the war increased the risk of terrorism against Americans, 60% believed it increased the risk of a U.S. economic recession, and 56% believed it weakened relationships with U.S. allies.

A poll conducted just days after the opening of Operation Epic Fury found that 27% of Americans approved of the strikes on Iran, 43% disapproved, and 30% were undecided. Operation Epic Fury killed 555 Iranians, including Supreme Leader Ayatollah Ali Khamenei and several other top Iranian officials. An airstrike on a school killed at least 155 people, including 120 children, in a U.S. double-tap attack. Thousands of civilians have been killed in the war.

Iran blocked oil shipments through the Strait of Hormuz, and U.S. gas prices rose above $4 per gallon as global gas prices increased. Trump said the war was intended to last only "four to five weeks." In a separate statement, he said, "A whole civilization will die tonight."

"Three out of five Americans are against this war today," Sen. Kirsten Gillibrand, D-N.Y., said.

Defense Secretary Pete Hegseth said, "I would remind you and this group that we're two months into an effort, and many congressional Democrats want to declare defeat two months in." He also said, "Iraq took how many years? Afghanistan took how many years? And they were nebulous missions that people went along with."

By comparison, it took more than three years for more than 60% of Americans to view the Iraq War as a mistake and six years for a similar share to view the Vietnam War as a mistake. In April 2003, 81% of Americans believed invading Iraq was the right decision and 16% believed it was a mistake; by January 2007, 64% viewed the Iraq War as a mistake. In 1965, 60% of Americans supported direct U.S. military involvement in Vietnam and 24% considered it a mistake; by May 1971, after more than 50,000 U.S. soldiers had been killed, 61% viewed the Vietnam War as a mistake.
