President Biden warned Israeli Prime Minister Benjamin Netanyahu Thursday that the US would reconsider its support for Israel’s war against Hamas in the Gaza Strip if stronger protections aren’t put in place for civilians — following the “unacceptable” airstrike that killed seven aid workers, including an American, earlier this week.

During the half-hour call with Netanyahu, the White House said, Biden “made clear the need for Israel to announce and implement a series of specific, concrete, and measurable steps to address civilian harm, humanitarian suffering, and the safety of aid workers.

“He made clear that US policy with respect to Gaza will be determined by our assessment of Israel’s immediate action on these steps,” the readout added.

Officials did not specify what about US policy might be different, but National Security Council spokesman John Kirby told reporters the administration wanted to see improvements in the humanitarian situation in the “coming hours and days.”

“If we don’t see changes from their side, there’ll have to be changes from our side, but I won’t preview what that’ll look like,” he said while still referring to the Jewish state as a “friend and ally” of the US.

Kirby added that Biden had been “shaken” by Monday’s attack on a three-car convoy carrying relief workers with World Central Kitchen in northern Gaza. American Jacob Flickinger was among those killed in the attack.

The Israel Defense Forces chief of staff apologized for the strike early Wednesday, saying it stemmed from a “misidentification” and “shouldn’t have happened.”

It was not immediately clear whether Netanyahu had apologized privately to Biden for the deadly mishap.

Meanwhile, the New York Times reported Wednesday that Biden had told a gathering of Muslim community leaders the previous evening that first lady Jill Biden had urged him to more forcefully advocate for a halt to the fighting in the Hamas-controlled enclave.

When an attendee told Biden his wife had disapproved of him coming to the White House because of the president’s support for Israel, according to the report, Biden said he understood and added that the first lady had urged him to “stop it, stop it now” in reference to the Middle Eastern war.

Biden also told Netanyahu “that an immediate cease-fire is essential to stabilize and improve the humanitarian situation and protect innocent civilians,” the White House said.

The leaders also discussed the need to reach an agreement on hostage negotiations with Hamas, which is believed to hold about 130 captives — including several Americans — alive or dead, and Iranian threats against Israel.

Earlier this week, Iranian leaders vowed to hit back after an Israeli airstrike destroyed Iran’s consulate in Damascus, Syria — killing 12 people, including two elite Iranian generals. Iran’s President Ebrahim Raisi said Wednesday the attack “will not remain without answer.”

There was no immediate reaction to the call from the Israeli government, with Netanyahu coming under increasing pressure to call an early election amid criticism over his conduct of the war.

Following the president’s call with Netanyahu, US Secretary of State Antony Blinken echoed Biden’s remarks in Brussels, where he had gone to mark the 75th anniversary of the founding of NATO. 

“Despite important steps by Israel to allow assistance into Gaza, results on the ground are woefully insufficient and unacceptable,” Blinken said. “Unlike Hamas, Israel is a democracy and democracies place the highest value on human life.

“This week’s horrific attack on World Central Kitchen workers was not the first incident, but must be the last,” he added. 

World Central Kitchen, founded by restauranteur José Andrés to provide immediate food relief to disaster-stricken and war-torn areas, has called for an independent investigation into the IDF airstrike, which also killed three British nationals along with relief workers from Australia and Poland, as well as their Palestinian driver.

Despite the uproar over the erroneous airstrike, the Biden administration has proceeded apace with arms transfers and deliveries to Israel, many of which were approved years ago but are only now being fulfilled.

On Monday, the White House’s list of munitions transfers included the sale to Israel of more than 1,000 500-pound bombs and more than 1,000 1,000-pound bombs.

At the White House, Kirby confirmed that the US “haven’t really sent emergency aid and military assistance to Israel” since the Gaza war was in its earliest months.

The WCK strike is the latest blow to Biden and Netanyahu’s already tense relationship.

Biden privately called Netanyahu a “bad f–king guy” in February, according to sources close to the president, and the two went weeks without speaking following Biden’s Feb. 8 comment that the Israeli response to Hamas’ Oct. 7 attack that killed an estimated 1,200 people — including 33 Americans — had been “over the top.”

The president also allegedly hung up the phone on Netanyahu back in December while criticizing the prime minister’s handling of the war and lack of progress on the hostage exchange deal.

While the Biden administration has reaffirmed that the US backs Israel –for now — in its war against Hamas terrorists, Sen. Chris Coons (D-Del.) said the attack on aid workers justifies a review of whether the US will place conditions for delivering future aid to Israel.

“I think we’re at that point,” Coons, a member of the  Senate Foreign Relations Committee, told CNN just before Biden’s call with Netanyahu. “I think we’re at the point where President Biden has said — and I have said and others have said — if Benjamin Netanyahu, Prime Minister, were to order the IDF into Rafah at scale, they were to drop thousand-pound bombs and send in a battalion to go after Hamas and make no provision for civilians or for humanitarian aid, that I would vote to condition aid to Israel.”
