After more than a week of public pressure from the U.S. for “humanitarian pauses” in Gaza, Israeli Prime Minister Benjamin Netanyahu on Monday allowed that his government might be open to only “little pauses” in its assault on Hamas. The Israeli leader sought to play down differences with his country’s most vocal backer on the world stage at a time of rising scrutiny of the sharply rising civilian toll of fighting.

Netanyahu spoke after President Joe Biden made a direct appeal to him nearly a month into the war seeking to rally support behind securing even limited relief for civilians in the spiraling conflict. The back-and-forth spotlighted the challenges facing Biden and his administration as they seek to manage what is emerging as one of the defining foreign policy crises of his presidency.

The U.S. thus far remains focused on keeping the fighting from exploding into a wider regional war and pushing for limited steps to alleviate civilian suffering. But it has remained steadfastly behind Israel and Netanyahu’s goal of ending Hamas control over Gaza, even as the death toll in Gaza reached 10,000, according to the Hamas-run health ministry.
