WASHINGTON (AP) — Most Americans say the war in Iran has not been worth fighting, and President Donald Trump’s approval rating on Iran has fallen slightly since last month , according to a new AP-NORC poll. About two-thirds of U.S. adults say the war with Iran, which began Feb. 28 , has not been worthwhile, according to the new poll from The Associated Press-NORC Center for Public Affairs Research. Just 28% of U.S. adults now approve of how Trump is handling Iran, a slight decline from 34% last month. Roughly 61% of Republicans approve of how Trump is handling Iran, an apparent decline from 71% in June. About half of Republicans say the U.S. should continue military action against Iran, particularly those who identify as “very conservative.”
