A Reuters/Ipsos poll released July 13 finds that most Americans expect the United States’ conflict with Iran to last longer than weeks. The survey was conducted over three days ending Sunday as fighting escalates and President Donald Trump declares a blockade of Iranian shipping in the Gulf. The poll shows 79% of respondents believe U.S. military involvement in Iran will “go on for an extended period of time,” up from 65% reported in a similar late-March Reuters/Ipsos poll. Only 18% of respondents expect the conflict to end “pretty quickly in a matter of weeks.” The results suggest a shift toward longer-duration expectations among Americans as the situation intensifies. The poll’s findings reflect public sentiment at the time of fieldwork, alongside official developments including Trump’s blockade announcement and the broader escalation of hostilities. The outlet reports the poll’s methodology and comparative figures from late March, emphasizing the change in expectations over time.
