JERUSALEM — Benny Gantz, a centrist member of Israel’s three-man war Cabinet, announced his resignation Sunday, accusing Prime Minister Benjamin Netanyahu of mismanaging the war effort and putting his own “political survival” over the country’s security needs.

Netanyahu More Reliant on Far-right Allies

The move does not immediately pose a threat to Netanyahu, who still controls a majority coalition in parliament. But the Israeli leader becomes more heavily reliant on far-right allies who oppose the latest U.S.-backed cease-fire proposal and want to press ahead with the war.

“Unfortunately, Netanyahu is preventing us from achieving true victory, which is the justification for the painful and ongoing price,” Gantz said. He added that Netanyahu was “making empty promises,” and the country needs to take a different direction as he expects the fighting to continue for years to come.

The popular former military chief joined Netanyahu’s government shortly after the Hamas attack in a show of unity. His presence also boosted Israel’s credibility with its international partners. Gantz has good working relations with U.S. officials.

Gantz had previously said he would leave the government by June 8 if Netanyahu did not formulate a new plan for postwar Gaza.

274 Palestinians Killed in Hostage Operation

He scrapped a planned news conference Saturday night after four Israeli hostages were dramatically rescued from Gaza earlier in the day in Israel’s largest such operation since the eight-month war began. At least 274 Palestinians, including children, were killed in the assault, Gaza health officials said.

Gantz called for Israel to hold elections in the fall, and encouraged the third member of the war Cabinet, Defense Minister Yoav Gallant, to “do the right thing” and resign from the government as well. Gallant has previously said he would resign if Israel chose to reoccupy Gaza, and encouraged the government to make plans for a Palestinian administration.

On Saturday, Netanyahu had urged Gantz not to leave the emergency wartime government.

“This is the time for unity, not for division,” he said, in a direct plea to Gantz.

Gantz’s Resignation is Largely “Symbolic”

Gantz’s decision to leave is largely “a symbolic move” due to his frustration with Netanyahu, said Gideon Rahat, chairman of the political science department at the Hebrew University of Jerusalem. He noted it could further increase Netanyahu’s reliance on extremist, right-wing members of his government, led by National Security Minister Itamar Ben-Gvir and Finance Minister Bezalel Smotrich.

“I think the outside world, especially the United States, is not very happy about it, because they see Gantz and his party as the more responsible people within this government,” Rahat said.

On Sunday evening, Ben-Gvir demanded a spot in the war Cabinet, saying Gantz and the smaller Cabinet had bungled the war effort due to “dangerous” ideological decisions.

Hamas took some 250 hostages during the Oct. 7 attack that killed about 1,200 people. About half were released in a weeklong cease-fire in November. About 120 hostages remain, with 43 pronounced dead. At least 36,700 Palestinians have been killed in the fighting, according to Gaza’s Health Ministry, which does not distinguish between fighters and civilians.
