Six days after the U.S. attacked Iran as part of a joint operation with Israel, opinion polls reveal grave doubts among the American public about the endeavor.

A Reuters/Ipsos poll conducted right after hostilities began found only 27% of surveyed Americans approve of the U.S. actions against Iran, while 43% disapproved and 29% said they were unsure.

The lack of public support spells political peril for Trump, even as he enthuses about how well American actions are going, celebrates the killing of Iranian Supreme Leader Ayatollah Ali Khamenei and suggests that U.S. operations against the Islamic Republic will likely only last four weeks or so.

Trump has so far abjured the traditional modes of wartime communication, such as a prime-time televised address to the nation. He has instead opted for a combination of videos released on his own social media accounts, extemporaneous remarks at White House events and a succession of brief, on-the-record phone interviews with journalists.
