It has become clear that Prime Minister Benjamin Netanyahu of Israel is not the leader for this critical moment.

The devastation of Gaza is at intolerable levels and getting worse; the Israeli government is under intense pressure from the families of hostages to do far more to free them before they perish; the United States and Arab states, anxious to avoid a regional war, are trying to mediate an end to the conflict. But Mr. Netanyahu blocks the way.

As a majority of Israelis and their allies can see, Mr. Netanyahu and his insistence on “total victory” over Hamas, with no consideration of the consequences or costs, have become a part of the problem. He is playing a cynical game, using the war to serve his political ends, and Israelis, most of whom support the effort to wipe out Hamas, are getting tired of it.

He has even managed to alienate Israel’s most important ally. Despite President Biden’s display of total support for Israel — and Mr. Netanyahu — after the atrocious attack by Hamas on Oct. 7, including the president’s personal visit to the Jewish state, Mr. Netanyahu has deliberately and publicly defied American advice as contrary to Israel’s “vital interests.” A particularly contentious conversation in late December ended with Mr. Biden angrily declaring, “This conversation is over.” It was a month before Mr. Biden phoned again.

The problem is not necessarily Mr. Netanyahu’s hawkish stance, which is shared by many Israelis enraged by the barbaric Hamas raid. It is Mr. Netanyahu’s confusion of leadership with political survival, with the widespread perception that he opposes any negotiated settlement, and any American advice or mediation, not because he really believes they run counter to Israelis’ interests, as he claims, but because appearing to stand up to “American pressure,” and portraying the Gaza war as a far broader conflict about a Palestinian state and Iran, serves his political ends.

That, at least, appears to be what a majority of Israelis believe, even those who might otherwise align with the prime minister’s insistence on trying to fully eradicate Hamas. According to a political poll taken in late December, only 15 percent of Israelis wanted him to stay in office after the war ended.
