The poll, conducted by the Hebrew University of Jerusalem in partnership with the Agam Institute between June 17 and June 20, surveyed 3,644 respondents and found widespread concern about Israel’s strategic position following the conflict and diplomatic settlement.

According to the survey, 92.1 percent of respondents said Iran had either won the conflict or gained more from its outcome than Israel, while 82.9 percent believed Israel’s long-term security position had deteriorated as a result of the war and the subsequent U.S.-Iran agreement.

The findings suggest dissatisfaction extended across Israel’s political spectrum. Among supporters of Prime Minister Benjamin Netanyahu’s right-wing governing bloc, 93.1 percent said Iran had emerged as the victor or principal beneficiary of the conflict.

Opposition to the agreement between Washington and Tehran was also pronounced. Nearly two-thirds of respondents, 63.2 percent, opposed the deal, while only 12.1 percent expressed support. The remainder were either undecided or did not state a preference.

The survey also highlighted declining confidence in Netanyahu’s leadership during the conflict. Some 72.5 percent of respondents said they did not believe the prime minister’s assessment of the military campaign’s achievements, while 56.4 percent rated his management of the conflict as either poor or unsuccessful.

Support for Netanyahu’s continued premiership also appeared to weaken. The poll showed backing for the Israeli leader falling to 29.4 percent in June from 40.5 percent recorded in early March, indicating a significant erosion in public support over the course of the conflict.

Despite concerns about the outcome of the war, the survey found continued public backing for a hardline security approach toward Hezbollah in neighboring Lebanon. Nearly half of respondents, 48.2 percent, supported renewed large-scale military action against the Iran-backed group, even if such a move risked friction with the United States. By comparison, 21 percent opposed further escalation.

The release of the survey coincided with efforts to advance diplomatic negotiations between Washington and Tehran. Representatives from both countries were scheduled to meet in Switzerland on Sunday to discuss transforming the temporary agreement into a more durable framework.

The diplomatic process faces additional uncertainty amid tensions on Israel’s northern border. A renewed ceasefire announced by Washington on Friday followed clashes between Israeli forces and Hezbollah fighters in southern Lebanon, with both sides accusing each other of violating the truce.

The poll’s findings underscore the political and strategic challenges facing Israel’s leadership as it seeks to reassure the public about the country’s security posture while navigating a rapidly evolving regional landscape shaped by diplomacy, military confrontation and shifting alliances.
