Poll finds that Americans are concerned about impact of the war on the cost of living and sceptical of success thus far.

A new poll has found that a large majority of people in the United States believe that the decision to take military action against Iran was a mistake, as the war roils the global economy and fuels cost-of-living concerns in the US.

A Washington Post-ABC-Ipsos poll released on Friday shows that 61 percent of respondents believe the use of military force against Iran was a mistake, with just 36 percent saying it was the right decision.

The poll is the latest to find low levels of support for the war launched against Iran by the US and Israel in late February, which has killed thousands of people across the Middle East and sent global energy prices surging.

Asked if they had changed their behaviour due to higher gas prices, 44 percent of respondents said they had cut back on driving, and 42 percent said they had done the same for household expenses. Those figures increased to 56 percent and 59 percent for respondents making less than $50,000 per year.

Those concerns come at a time when President Donald Trump’s approval ratings have dropped to new lows, with voters expressing frustration over economic issues and the cost of living.

The war has also been depicted as a contrast with Trump’s promise to keep the country out of unnecessary foreign wars, and 46 percent of respondents said the decision to attack Iran was inconsistent with the position Trump took during his presidential campaign.

Despite relatively low casualty figures among US forces, the poll found that the war on Iran is as unpopular as the Iraq War was during a period of heightened violence in 2006 and the Vietnam War was in the early 1970s.

Asked whether US military actions against Iran have been successful thus far, 39 percent said they had been unsuccessful, while 19 percent said they had been successful. A plurality of 41 percent said it was too soon to tell.

Support for the war remains robust among members of Trump’s Republican Party, however. Nearly 80 percent of Republicans said that the decision to attack Iran was the correct one, even as they were split evenly between rating operations as successful or stating that it was too soon to tell.
