The war launched by the United States and Israel against Iran has reached its 100th day, but remains deeply unpopular among Americans. The conflict has become a political liability for President Donald Trump and his Republican Party, as public opinion surveys continue to show widespread opposition to the war. Many U.S. voters view the campaign as unnecessary and harmful to national interests.

A poll conducted by the University of Maryland’s Department of Peace and Development, led by Professor Shibley Telhami, found that only 16 percent of American voters believe the United States has won or is winning the war. The survey also revealed that 33 percent of Republicans and a majority of voters overall think the conflict has had more negative than positive effects on U.S. interests. Telhami described the findings as “remarkable,” noting that even Republicans increasingly see the war as damaging.

Experts cited in the report suggest that the lack of public support could politically weaken Trump ahead of the November midterm elections, where Democrats hope to regain control of Congress.
