Majority of American Jews Oppose U.S.-Israel Iran Operations, Poll Finds

A majority of American Jews oppose U.S.-Israeli military operations against Iran, according to a poll released Monday by the Jewish Electorate Institute. The survey of 800 registered Jewish voters, conducted March 13–23, found that 55% oppose the campaign, while 32% support it and 13% are undecided.

The findings come as fighting between the United States, Israel, and Iran continues, and reflect both broader American skepticism toward the conflict and significant internal divisions within the American Jewish community.

When asked about the stated objectives of the military action, 31% of respondents said they support it because Iran cannot be allowed to obtain a nuclear weapon. At the same time, 41% said they oppose the campaign because the United States should not go to war without clear provocation and defined objectives. Another 23% said they feel “torn,” citing Iran as a threat to peace but questioning the current approach.

The poll highlights sharp denominational divides. Among Orthodox Jews, 83% said they approve of the operations. In contrast, 67% of Reform Jews and 56% of non-denominational Jews said they disapprove. A plurality of Conservative Jews, 48%, also said they oppose the campaign.

“American Jews are not monolithic. There can be difference, and in this case strongly held on both sides, with a middle group torn between mixed feelings,” said Michael Bloomfield of the Mellman Group, which conducted the survey.

Beyond support for the operation itself, respondents expressed broad agreement on the need for congressional authorization. Some 73% said U.S. President Donald Trump should have sought approval from Congress before initiating military action, while 22% said he was right to act without it.

The survey also points to concerns about the longer-term impact of U.S.-Israel coordination. A majority of respondents, 54%, said they worry that cooperation in the campaign could create ongoing tensions surrounding the role of Israel and American Jews in U.S. foreign policy. By contrast, 32% said joint operations would likely make the effort more effective and improve the chances of achieving shared goals.

The results broadly align with wider U.S. public opinion, where multiple recent surveys have found more Americans oppose the military action than support it, with divisions often falling along political lines.

At the same time, the issue appears likely to shape conversations within the Jewish community itself. According to the Jewish Electorate Institute, 60% of respondents said they expect the Iran conflict to be discussed at Passover Seder gatherings, while 56% anticipate discussions about antisemitism in the United States.
