The poll of 3,644 respondents, conducted between June 17 and 20 by the Hebrew University of Jerusalem (Al-Quds) in collaboration with the Agam Institute, paints a stark picture of public sentiment following the Iran-US deal.

Of those surveyed, 92.1 per cent said Iran had won or gained more from the conflict, while 82.9pc felt that Israel’s long-term security had been weakened.

The survey found that even among voters who support the right-wing bloc, the electoral base of the Israeli regime's prime minister, Benjamin Netanyahu, 93.1pc believed Iran had won.

The findings pointed to a broader crisis of confidence in Israel’s leadership.

Nearly three-quarters of those surveyed, 72.5pc, said they did not believe Netanyahu’s claims about the military campaign’s achievements, while 56.4pc rated his management of the campaign as “failed” or “poor”.
