The findings pointed to a broader crisis of confidence in Israel’s leadership.
Nearly three-quarters of those surveyed, 72.5 per cent, said they did not believe Netanyahu’s claims about the military campaign’s achievements, while 56.4 per cent rated his management of the campaign as “failed” or “poor”.
The poll also pointed to the political price paid by Netanyahu, with support for his premiership plummeting from 40.5 per cent in early March to 29.4 per cent in June.
Despite this, the survey found ongoing support for military action against Hezbollah in Lebanon.
Nearly half of respondents, 48.2 per cent, backed renewed major military action against Hezbollah in Lebanon, even if it risked confrontation with Washington, while only 21 per cent opposed such a move.
Negotiations to turn the temporary Iran-US agreement into a more permanent deal were to take place in Switzerland on Sunday, despite the conflict in Lebanon threatening negotiations.
Washington announced a renewed ceasefire there on Friday after Israeli troops clashed with Hezbollah fighters in southern Lebanon, with each side accusing the other of breaking the truce.
