The survey, conducted by the Hebrew University of Jerusalem in collaboration with the Agam Institute, polled 3,644 respondents between June 17 and 20 and reflects widespread public concern over Israel’s strategic position following the deal.

According to the findings, 92.1% of respondents said Iran either won or benefited more from the conflict, while 82.9% believed Israel’s long-term security had been weakened.

Even among right-wing voters aligned with Prime Minister Benjamin Netanyahu’s coalition, 93.1% said Iran had come out ahead.

Opposition to the US-Iran agreement was also strong, with 63.2% of respondents opposing the deal, compared with 12.1% in support.

The poll suggests a broader decline in public confidence in Israel’s leadership.

About 72.5% of respondents said they did not believe Netanyahu’s claims regarding the success of the military campaign, while 56.4% described his handling of the operation as “poor” or “failed”.

Netanyahu’s approval ratings have also fallen sharply, dropping from 40.5% in March to 29.4% in June, according to the survey.

Despite this, support remains for continued military action against Hezbollah in Lebanon, with 48.2% backing renewed large-scale operations even at the risk of confrontation with the United States. Only 21% opposed such action.

The findings come as US and Iranian officials continue efforts in Switzerland to convert a temporary agreement into a more lasting deal, even as tensions persist in Lebanon following recent clashes between Israeli forces and Hezbollah despite a fragile ceasefire.
