At 260 days into the Iraq war, Gallup found 60 percent. The first is that the Iran war was a war of choice with no domestic trigger. Stephen Semler, who analyzed 153 surveys across seven conflicts, concluded the Iran war is the only American war to begin with net support underwater. CNN reported this week that while the Iran war is unusually unpopular, it does not dominate public attention the way earlier wars did. Eighteen U.S. service members have been killed in the Iran war since February, four of them in the past week.
