The administration of President Joe Biden has begun to publicly air its differences with the Israeli government over the conduct of the war in Gaza, expressing its exasperation even as it remains largely steady in its support.
Biden referred this week to "indiscriminate bombing" in Gaza, underscoring his frustration with conservative Israeli Prime Minister Benjamin Netanyahu, whose government Biden agrees is starting to lose global support.
The Democratic US administration is even beginning to talk about a "timetable" for how long Israel's high-intensity military operations can continue.
Warnings have multiplied in recent weeks, with senior US officials such as Vice President Kamala Harris and Secretary of State Antony Blinken speaking of the "far too high" number of Palestinian civilians killed, and the gap between commitments made by Israel to respect civilian lives and the reality on the ground.
Israel has pounded Gaza day after day since the start of the conflict on October 7, interrupted only by a brief humanitarian truce at the end of November.
Defense Secretary Lloyd Austin recently warned Israel of what is at stake: "In this kind of a fight, the center of gravity is the civilian population. And if you drive them into the arms of the enemy, you replace a tactical victory with a strategic defeat."
But Washington, Israel's main diplomatic and military ally, has been careful not to openly criticize its ally, and has resisted calls for a ceasefire, which it said would benefit Hamas, despite international pressure.
Indeed, the United States appears increasingly isolated in its support, as evidenced by Tuesday's vote in the UN General Assembly calling for such a ceasefire, passed by 153 member states, with only the US and nine other states voting against and 23 abstaining.
The trigger for the war was the bloody October 7 assault by Hamas militants on Israel.
Since then, the Biden administration has pressed its ally to unblock humanitarian aid for people in Gaza, work to free hostages kidnapped by Hamas on the day of the attack, and adopt a more targeted military strategy.
In private, US diplomats have made no secret of their dissatisfaction with Israel's conduct of the war.
As a sign of the US pressure on Israel, National Security Advisor Jake Sullivan will visit Israel on Thursday and Friday, the White House said.
"I will certainly be talking to the PM, the war cabinet and senior Israeli officials about timetables, about how they are thinking about that," Sullivan told the Wall Street Journal on Tuesday, suggesting a shift from the "high intensity military operations of the kind we have seen over the past weeks."
For his part, Biden at the White House on Wednesday received for the first time families of US hostages held in Gaza by Hamas, a senior official said.
If there is a shift in the US position toward Israel, it may reflect the domestic political situation as well.
"There is a lot of pressure on the Biden administration among his own party and constituency" on policy toward Israel, said James Ryan, director of the Middle East program at the Foreign Policy Research Institute, a nonprofit think tank.
But any shift also signals "a tacit admission" of limited US ability to influence the Israeli government, he added.
Differences also loom over views on what happens after the war ends.
Washington insists on a two-state solution as the only way to resolve the Israeli-Palestinian question in the long term, which Israel rejects.
As far as who would govern in post-conflict Gaza, the US and Israel are at odds over the idea of handing reins to a revitalized Palestinian Authority.
"A revitalized, reformed and reorganized Palestinian Authority is the way forward for the governance of a reunited West Bank and Gaza," State Department spokesman Matthew Miller said on Wednesday.
