Two-thirds of Americans believe the war in Iran has not been worth fighting. A new AP-NORC poll found that roughly two-thirds of U.S. adults say the war that began Feb. 28 is not worthwhile. The sentiment is shared by the vast majority of Democrats (87%) and independents (68%), as well as 37% of Republicans. The AP-NORC poll, conducted July 23-27, surveyed 1,165 adults and has a margin of sampling error of plus or minus 3.7 percentage points.
