Israel’s influential minister of strategic affairs, Ron Dermer, resigned from his post on Tuesday, three years after assuming the role.

“This government will be defined both by the attack on October 7th and by the prosecution of the two-year, seven-front, war that followed,” Dermer, widely regarded as Prime Minister Benjamin Netanyahu’s closest advisor, wrote in his resignation letter.

Israeli media had reported for months that Dermer’s departure was expected.

Dermer noted that he had initially promised his family to work in the position for two years only, but extended his tenure twice, with their blessing, “first to work with you [Netanyahu] to remove the existential threat posed by Iran’s military nuclear capability and second to end the war in Gaza on Israel’s terms and bring our hostages home.” 

Dermer has led Israel’s ceasefire and hostage-release negotiations since February. He is expected to stay on as Netanyahu’s envoy to continue handling the future of the Gaza portfolio, political sources recently told Jewish Insider. U.S.-born and a former Israeli ambassador to Washington, Dermer has long played a central role in managing Israel’s relationship with the U.S.

“What the future holds for me, I do not know. But I do know this: No matter what I do, I will continue to do my part to help secure the future of the Jewish people,” Dermer said.
